Resumen ∙ El Pato de los Torrentes (Merganetta armata) es un ave especialista de ríos de aguas rápidas que se distribuye por la cordillera de los Andes desde el sur de Argentina y Chile hasta Venezuela. Aquí aportamos nueva información sobre eventos de dispersión a través de un registro casual y seguimiento de ejemplares anillados en Argentina. Nuestras observaciones sugieren eventos de dispersión crepusculares y nocturnos, un juvenil fue registrado volando de noche sobre tierra firme, a 300 metros del cuerpo de agua más cercano. Las distancias de dispersión fueron en general bajas (2–9 km). Sin embargo, un macho anillado se desplazó entre 22 y 84 km de distancia, dependiendo de si la ruta empleada fue volando sobre tierra firme o realizada siguiendo cursos de agua, respectivamente. Es necesario estudiar la capacidad dispersiva de esta especie para determinar el potencial de aislamiento genético entre poblaciones y probables barreras geográficas.Abstract ∙ Observations on dispersal events of Torrent Ducks (Merganetta armata) The Torrent Duck (Merganetta armata) is a white‐water river specialist distributed along the Andes from southern Argentina and Chile to Venezuela. Here we provide new information on dispersal based on ringed individuals and occasional records from Argentina. Our observations suggest nocturnal or crepuscular dispersal events, a juvenile was recorded flying at night on land, 300 m away from the nearest shore. Dispersal distances were in general low (2–9 km). However, one ringed male dispersed between 22 and 84 km, depending on whether it flew over land or followed watercourses, respectively. It is necessary to study the dispersal ability of this species to determine the potential for genetic isolation between different populations and likely geographical barriers.

Abstract ∙ Feathers are one of the defining characteristics of birds and serve a critical role in thermal insulation and physical protection against the environment. Feather structure is known to vary among individuals, and it has been suggested that populations exposed to different environmental conditions may exhibit different patterns in feather structure. We examined both down and contour feathers from two populations of male Torrent Ducks (Merganetta armata) from Lima, Peru, including one high‐altitude population from the Chancay‐Huaral River at approximately 3500 m a.s.l. and one low‐altitude population from the Chillón River at approximately 1500 m a.s.l.. Down feather structure differed significantly between the two populations. Ducks from the high‐altitude population had longer, denser down compared with low‐altitude individuals. Contour feather structure varied greatly among individuals but showed no consistent difference between populations. These results suggest that the innermost, insulative layer of plumage (the down), may have developed in response to lower ambient temperatures at high elevations. The lack of observable differences in the contour feathers may be due to the fact that this outer plumage layer is more important as waterproofing than insulation.Resumen ∙ La estructura del plumón del Pato de los Torrentes (Merganetta armata) varia entre bajas y grandes altitudes en los Andes El plumaje es una característica que define a las aves y cumple roles críticos en el aislamiento térmico y protección física del ambiente. Se sabe que la estructura de las plumas varía entre individuos, y se ha sugerido que poblaciones expuestas a diferentes condiciones ambientales pueden exhibir diferentes patrones en la estructura de las plumas. En este estudio se examinaron tanto el plumón como las plumas de contorno de machos adultos del Pato de los Torrentes (Merganetta armata) de dos poblaciones, una en el río Chancay‐Huaral a 3500 m s.n.m. y otra en el río Chillón a 1500 m s.n.m., ubicadas en Lima, Perú. La estructura de plumón difiere significativamente entre las dos poblaciones. Los patos de la población a mayor altitud presentan un plumón más largo, y denso que sus congéneres de menor altitud. La estructura de las plumas de contorno varía ampliamente entre individuos, pero no muestra diferencias significativas entre poblaciones. Estos resultados sugieren que las diferencias entre las capas interiores de aislamiento del plumaje (plumón), pueden haberse desarrollado como respuesta en ambientes de bajas temperaturas a grandes elevaciones. En cambio, la ausencia de diferencias detectables en las plumas de contorno puede deberse al hecho de que esta capa externa es más importante en la impermeabilización que en el aislamiento.

El Pato de los Torrentes (Merganetta armata) es una especie poco conocida que habita ríos de montaña de aguas rápidas desde el sur de Argentina y Chile hasta Venezuela. Debido a que la especie habita en ríos de gran porte, donde es muy dificultosa y arriesgada su captura, se presenta un nuevo método, utilizando la fotoidentificación. Utilizando las líneas de la cabeza de los machos de la especie, que presentan diseños únicos, se pueden generar bancos fotográficos que permitan monitorear individuos a los largo del tiempo. El método ha sido puesto a prueba teniendo en cuenta la estabilidad del patrón entre mudas, la comparación de fotografías de numerosos ejemplares salvajes y de pieles de museos y la capacidad de distintos observadores para distinguir diferentes ejemplares y a los mismos ejemplares en diferentes años.

Full textAbstract:
Vargas Llosa aborrece de ese afán tan telúricamente latinoamericano de trasladar a la literatura torrentes de palabras exóticas. Aplica un bisturí para extraer del léxico real tan sólo algunos términos y algunas maneras de hablar que dan un ligero color local a la narración sin que ésta se vuelva incomprensible. En un brevísimo fragmento de la novela, sin embargo, parecería a primera vista una concesión excepcional a ese «folclorismo» del que tanto trataba de distanciarse: los piuranos llaman a eso de tal modo y a eso otro de esta otra manera. Un análisis riguroso descubre que es parte de la ficción y que al incorporar algunos de los vocablos aparentemente registrados por el novelista, la lexicografía peruana ha caído en una pequeña y muy ingeniosa trampa.

Full textAbstract:
In this work, the model of development of the P2P file exchange network organized by a torrent tracker is considered. The model is constructed on the basis of ordinary differential equations. The phase variables describing a status of a torrent tracker and the network organized by it (in first approximation is the number of the users of the tracker who are actively participate in information exchange, and the number of active torrents) are defined, the factors influencing the change of users number and the number of torrents are analyzed. On the basis of the analysis the system of differential equations, in first approximation describing evolution of the file exchange network organized by the torrent tracker — a hard dynamic model of evolution of the torrent tracker is written. Equilibrium points of hard model of evolution of the tracker are investigated, their possible quantity and type is described. All configurations of the general provision, possible in a hard model of evolution of the torrent tracker are described. The phase portrait of the hard model is represented. On the basis of the analysis of the hard model the system of differential equations describing evolution of a file exchange network with accounting of dependence of new users inflow intensity on a total quantity of potential audience of the torrent tracker, and also dependences of speed of torrents extinction on the number of users falling on one torrent — a soft dynamic model of evolution of a torrent tracker is written. Equilibrium points of a soft model of tracker evolution are investigated, their possible quantity and type is described. All configurations of the general provision, possible in a soft model of evolution of the torrent tracker are described. Phase portraits of each configuration are represented. The ratio of parameters necessary for the stability of the tracker a stable status is received. The influence of different administrative measures on a stock of the tracker stability in whole is analyzed. The need of support of torrents by administration at highly specialized torrent trackers with small potential audience is shown.

In the foothills of Shiwalik Himalaya, torrents are the prominent seasonal land features and characterized by high sediment ladder flash flow during monsoon period. These torrents have low banks and thus the flow frequently over tops the banks and causes floods in foot hill region to agricultural plain area. In present study, morphological, water and soil characteristics were studied with special references to torrential behavior and flow mechanics of torrent at Sabhawala watershed in Doon Valley of Garhwal Himalaya. The torrent gradient had varied from 1-75 to 2-62 % with flow velocity was 0.30 - 0.95 ms-1, occurred in Sabhawala watershed. Different forms of soil texture of torrent were observed and pH slightly alkaline consisting organic matter (%) as 0.24-0.95 in different zones of torrent The present study will provide resource based data for remedial measurement of torrent in other watersheds of Himalayan region.

Objetivos: analizar la emergencia de la agroecología como una narrativa glotopolítica agroalimentaria en América Latina. Metodología: se seleccionaron investigaciones sobre agroecología publicadas entre 2011 y 2018 y se deconstruyeron a través de un acercamiento lexicométrico para distinguir conceptos superlativos agroecológicos por medio de nubes semánticas. Resultados: se obtuvieron torrentes semánticos a nivel de regiones y países, que mostraron la complejidad sistémica de la agroecología latinoamericana. Limitaciones: se requieren más instrumentos metodológicos para ampliar el análisis semántico. Valor: el acercamiento a la complejidad semántica agroecológica de América Latina usando consorcios epistemológicos diversos es pertinente en estos tiempos en que la agroecología emerge dentro de las narrativas institucionales de reguladores globales del sistema agroalimentario. Conclusiones: el campo semántico de la agroecología es un área de contingencias entre una plétora de actores sociales locales, regionales y globales que luchan por determinar la propia narrativa de la sustentabilidad del sistema agroalimentario y, por lo tanto, incidir en la biopolítica mundial.

Full textAbstract:
Este estudio reporta las cantidades de material leñoso de gran tamaño (large woody debris o LWD) y los efectos asociados sobre la morfología del cauce y la hidráulica del flujo en dos cuencas de montaña de la zona “templada-cálida con lluvias invernales” de la Cordillera de los Andes, en Chile. Las cuencas analizadas del río Toro y del torrente Tres Arroyos (área de drenaje de 9 y de 11 km2, respectivamente) se ubican en la Región de la Araucanía, Chile y se caracterizan por una cobertura forestal de bosques nativos de Nothofagus y Araucaria. Cantidad, características y dimensiones de los residuos leñosos (>10 cm de diámetro, >1 m de largo) fueron examinados en los canales, así como sus efectos sobre la morfología del cauce, sobre su hidráulica y sobre el almacenamiento de sedimento; se realizó además, un monitoreo del desplazamiento de los troncos durante un periodo de un año para determinar el grado de movilidad de las piezas leñosas. Los resultados demuestran que existen grandes diferencias en la abundancia d LWD en los cauces de las dos cuencas estudiadas, posiblemente debidas a las diferentes alteraciones naturales que ocurrieron en las laderas de las cuencas. En el torrente Tres Arroyos se encontraron volúmenes medios de 700 m3ha-1, mientras que en el río Toro los valores registrados son de solamente 117 m3 de residuos leñosos por hectárea de superficie del cauce. Esta diferencia se puede justificar con el hecho que la primera cuenca fue afectada por incendios entre los años 1930 y 1940 seguidos por deslizamientos y flujos de detritos, mientras que la segunda, a pesar que sufrió un incendio que quemó toda la superficie forestal de la cuenca, todavía no representa grandes deslizamientos y aportes de detritos leñosos al cauce, probablemente a causa del corto plazo entre el incendio (2002) y la fecha de las mediciones (Enero 2006). La consecuencia de estas diferencias de volúmenes se refleja en la morfología de los cauces: el Tres Arroyos presenta grandes acumulaciones y altos log-steps que entregan al canal un macro-perfil a escalones. Se estimó que las acumulaciones de LWD en el tramo estudiado del Tres Arroyos disipan el 27% de la energía potencial total de la corriente de agua, y que existen 2000 m3 de sedimentos depositados en el cauce principal aguas arriba de acumulaciones de LWD, que corresponden aproximadamente al 100% del aporte anual total de sedimentos de la cuenca. Por el contrario en el río Toro la influencia morfológica de los LWD es muy limitada por la total ausencia de log-steps o valley-jams.

Full textAbstract:
This paper reconsiders the anteriority of Robert Torrens’s theory of natural wage to that of David Ricardo. Ricardo was influenced by Torrens’s thinking when writing the chapter on “Wages” of the Principles. For many historians of economic thought, this influence is limited to Torrens’s focus on the socio-cultural aspect of necessity goods, which determine the natural price of labor. While this interpretation is consistent with that of Ricardo, we argue that the anteriority of Torrens to Ricardo more generally focuses on the method used by the latter to justify the indexation of money wages on the money price of subsistence goods. Finally, this paper shows that the tribute paid to Torrens by Ricardo paradoxically explains posterity’s misunderstanding of his theory.

Las direcciones de magnetización remanente de los 24 flujos de lava del volcán Iztaccihuatl muestran polaridad magnética normal, sugiriendo que el presente cuerpo del volcán se formó durante el periodo de Brunhes Chron. Esta juventud relativa de la montarla ha sido substanciada por medio de recientes pruebas de K-Ar para comprobar la edad geológica. Los análisis de dispersión de V. G. P. conceden una estimación de la desviación secular de 14.20°. Este valor es semejante al predicho en la latitud de Iztaccihuatl por recientes modelos de variación secular y a una media de variación paleosecular determinada por la distribución mundial de los torrentes de lava. La concordancia de la cantidad estimada de dispersión con la esperada indica que la erupción de las lavas de este volcán ocurrió probablemente durante un intervalo de tiempo bastante grande, como para haber obtenido un ejemplo representativo de variación secular; lo que significa que el volcanismo se extendió por un periodo de tiempo más corto que el de Brunhes Chron pero más largo o comparable a la escala temporal de la variación secular. La media de V. G. P. en el volcán Iztaccihuatl es estadísticamente indistinguible del polo geográfico.

Devido aos impactos ambientais negativos causados pelo uso intensivo do solo, expansão urbana e industrial e à importância dos recursos hídricos para manutenção das diversas formas de vida na Terra, tornam-se necessários dados para o planejamento e a gestão ambiental de bacias hidrográficas. Objetivou-se analisar a morfometria da bacia do ribeirão da Laje, uma das principais fontes fornecedoras de água para o abastecimento público da população urbana de Rio Verde (GO), apoiado em geotecnologias e obras de autores consagrados. A área de estudo apresenta variáveis morfométricas, geologia, solos e precipitação pluviométrica predominantemente favoráveis à sua conservação e à recarga de água. Entretanto, a forma alongada e possíveis ocorrências de chuvas intensas na cabeceira sujeitam a bacia hidrográfica às torrentes eventuais, podendo causar prejuízos ambientais e econômicos; a amplitude altimétrica máxima, as maiores declividades, a densidade hidrográfica, densidade de drenagem, Nitossolo Vermelho, Neossolo Litólico e a predominância de agricultura intensiva são favoráveis à perda de solos. Este estudo irá subsidiar o planejamento e a gestão ambiental dessa bacia hidrográfica, além de servir de base para outros trabalhos locais e de outras regiões, contribuindo para a disponibilidade hídrica em quantidade e qualidade adequadas aos usos múltiplos.

Full textAbstract:
Slushflows have been investigated in various regions of the Earth for more than forty years. Most of the observed events occurred in mountainous drainage basins at high latitudes, so relatively few observations and measurements are presented in the scientific literature. This particularly holds for slush torrents which are major slushflow events reaching supercritical flow velocities. Thus, information on dynamical features of slush torrents are rather limited, and most results are based on qualitative observations. On June 3,1995, during a field campaign in the Kärkevagge, a drainage basin in Swedish Lapland, a slush torrent could be observed and documented by a time series of photographs and by video recordings. Quantitative results from a photogrammetric analysis of the photographs show that the first wave front of that slush torrent reached peak velocities of more than 40 ms−1. A second wave front was able to reach even higher velocities due to the fact that the first wave had almost completely removed all snow from the transport path. Consequently, the viscosity of the flow was significantly reduced. To the author's best knowledge, these results are the first quantitative measurements of a slush torrent during its movement.

Se ha realizado una primera aproximación a la ocupación, durante época islámica, en el suroeste de Mallorca. Para ello, se ha utilizado desde la información documental disponible y la toponimia hasta métodos arqueológicos como la excavación y la prospección del territorio. El análisis espacial realizado ha mostrado una distribución de asentamientos rurales nucleada en torno a alquerías, puntos de captación de agua y asentamientos en altura. Estos diversos elementos materiales se articulan en valles que ofrecen grandes posibilidades agropecuarias y con abundantes recursos hídricos que son gestionados, en ocasiones, a través de enclaves estratégicos. Las distintas zonas de explotación se hallan individualizadas por accidentes geográficos que delimitan el territorio y su extensión. Sin embargo, los distintos núcleos de población aparecen vinculados mediante la captación de agua de los mismos torrentes y una red de caminos que comunica los diferentes asentamientos campesinos de toda la comarca. Finalmente, se ha podido consignar una serie de yacimientos con características muy singulares, que parecen asociarse a funciones relacionadas con contextos históricos concretos, como la conquista cristiana de la isla en 1229. Estos yacimientos aparecen indirectamente citados en las crónicas cristianas y árabes que relatan la conquista de Jaime I y los momentos previos a la misma, dando una idea de su importancia geoestratégica en la defensa de la isla.

Full textAbstract:
In the post-Fordist world, cities emerged as increasingly contested terrains upon which capital and ordinary citizens struggled to control the urban process. Henri Lefebvre discerned this contestatory dynamic early on and in response developed the ‘urban’, a concept that cleaves a critical pathway towards a host of material, cultural and ideological processes that attach to capitalist modernity. Around the same time, the Spanish novelist Gonzalo Torrente Ballester was working to sketch the contours of his magnus opus La saga/fuga de J.B. Torrente would eventually come to recognize the roles that the urban process and the socio-spatial dialectic play in mediating contemporary urban life. The present article thus carries out first a close reading of Torrente’s personal journals to detail the ascendency of the ‘urban dominant’ as a central structuring component of his fictional writings. Thereafter, the critical analysis of La saga/fuga de J.B. will reveal that the ‘urban dominant’ stands concealed at the heart of this notoriously complicated novel. This urban cultural studies reading of La saga/fuga de J.B. will argue that, like Lefebvre, Torrente denounces capital’s static conception of space at the same time that he draws upon historical movements of urban protest for textual inspiration. And what will eventually emerge is that, beyond a master of the metafictional novel, Torrente was also an astute observer of everyday life in the urban context.

Los materiales usados tradicionalmente para diques en restauración hidrológico-forestal provocan un impacto visual permanente. Para conseguir integrar la obra en el paisaje, se propone la construcción de diques de tierra compactada con paramento aguas abajo revegetable, los cuales se construyen con materiales procedentes del propio terreno. Esta construcción en tierra no se ha utilizado en España para corregir cárcavas o torrentes, pero sí para balsas de agua y grandes presas, obras longitudinales contra avenidas y otro tipo de construcciones o edificaciones. En este trabajo se propone una modificación del perfil clásico de los azudes de tierra, para poder reducir el volumen de obra, construyendo un perfil vertical aguas arriba, con un núcleo impermeable basado en la construcción de muros tapiales, y un perfil inclinado aguas abajo y revegetable. El tipo de muro tapial permite usar materiales y métodos constructivos tradicionales de la zona, respetando el medio ambiente, mientras que la revegetación del paramento aguas abajo asegura su integración en el paisaje. La comprobación del dique al vuelco, deslizamiento y resistencia del terreno aseguran su estabilidad y garantía. La comparación del coste de ejecución con el de otros perfiles clásicos (hormigón, mampostería gavionada) muestran la viabilidad de este tipo de obra para la corrección de zonas acarcavadas, en zonas de baja escorrentía y cuencas de materiales finos.

Full textAbstract:
Gonzalo Torrente Ballester’s novella, Ifigenia (1950) has been read consistently as a critique of the consolidating Francoist state of the 1940s and an early example of his ‘demythologizing’ technique. This article seeks to open discussion on aspects of the text that have not attracted critical attention to date. It traces the unacknowledged legacies of Euripides’ Iphigenia in Aulis in the text, most visible in both authors’ emphasis on the capacity of language for deceit. Drawing on Hannah Arendt’s The Origins of Totalitarianism, it argues that Torrente’s Ifigenia should be read not only in the context of post-Civil War Spain but also in the wider socio-political context of post-Second World War Europe. It argues that the consistent suppression of expression of emotion throughout the text produces an absence of tragedy in Torrente’s retelling of the myth, and outlines how this relates to the post-war contexts of Spain and Europe.

Full textAbstract:
La correction torrentielle des torrents les plus actifs a été lancée en France par la politique de restauration des terrains en montagne de 1882 sur la base de travaux pionniers plus anciens. Elle a d'abord mis à profit la correction active des hauts bassins par la lutte contre l'érosion à la source mais a aussi accompagné le développement de la protection passive des enjeux par le piégeage et la canalisation des écoulements dans les zones aval. Cette lutte contre l'érosion et les risques torrentiels induits fait toujours l'objet d'investissements publics pour entretenir les systèmes de protection existants et, si nécessaire, en construire de nouveaux. Les contextes environnementaux, socio-économiques et techniques d'implantation et de gestion de ces systèmes de protection ont évolué. Il y a donc matière à s'interroger sur l'usage actuel qui est fait des ouvrages de correction torrentielle et des plages de dépôts, ouvrages spécifiques au contexte torrentiel. Cet article rappelle en premier lieu un historique de leur émergence. La seconde partie liste les fonctions de ces ouvrages : quels effets qualitatifs pouvons-nous espérer de ces structures à la lumière de plus de 150 ans d'expérience ? La dernière partie donne quelques perspectives concernant l'usage de ces ouvrages : pourquoi faut-il maintenir une part de correction active malgré les difficultés associées ? Qu'est-ce qui peut justifier d'abandonner ou de détruire certains ouvrages ? Quelles nouvelles approches semblent émerger dans la conception de ces ouvrages, et plus particulièrement des plages de dépôt modernes.

In order to reduce the ecological damage and economic loss caused by mountain torrent disasters in the flooded basin, it’s very important to realize the self-repair of the ecosystem in a short time. Based on the analysis of the causes of mountain torrents, this paper summarizes three main parts of ecological restoration in the river basin, including rainwater storage, Sedimentation and wetland conservation. Taking a research base in Wenling, Zhejiang Province as an example, this paper also discusses the design methods of the landscape inside mountain torrent basins based on ecological restoration from these parts above. Finally, these methods were obtained and applied in design practice, providing more solutions and theoretical references for the ecological restoration design in the future.

The study conducted in arid areas of Dera Ghazi Khan occasionally affected by hill torrents (Suri-Lund, Vidore, Sakhi-Sarwar, Mithawan) coming from Koh-e-Suleman range. The study found that hill torrent water is used for agriculture, domestic and livestock. The management of this water significantly affects on income, crop yield, soil fertility, health conditions and living standard of farmers. The local cost effective methods to store this water include wah, dubba and bundh but most of water is wasted as they are insufficient. The water distribution mechanism fosters cooperation and helps to form new relations with co-farmers. The study suggested that government and NGOs should help people to construct concrete diversions, bundhs, ponds and dams to manage hill torrent water.

This paper analyzes how Robert Torrens's system of prices is applied to the aggregate economy. His personal interpretation of Say's Law is articulated with a numerical illustration and the Hawkins-Simon conditions to exemplify how the correct supply of the ingredients of capital is presented as a necessary condition for the full clearing of markets. Next, the possible causes of a shortage in effectual demand are discussed. The quantitative illustrations developed by Torrens are carefully reviewed to show how the monetary factors play a crucial role during the general glut, as well as the appropriate policy measures to stabilise the economy. The final comments reflect on the originality of Torrens's theoretical work.

Full textAbstract:
In Canada, debris torrents (also referred to as channelized debris flows) occur in parts of British Columbia, Alberta, and the Yukon. At least 17 deaths and an estimated $100 million of damage to bridges and property can be attributed to this natural hazard. The debris mainly comprises large boulders, rock fragments, gravel- to clay-sized material, tree and wood mulch—materials that accumulate in the mountain creeks. To be susceptible to a debris torrent, a creek must have a drainage area within a critical range, a profile that is sufficiently steep, an accumulation of debris, and some form of triggering mechanism. The most common triggering mechanism is an extreme water discharge, which may result from a very intense rainfall or a temporary damming of the creek. In western Canada, the resulting torrents involve masses of debris, typically less than 50 000 m3, that travel down creeks at speeds between 3 and 12 m/s.Several passive and active forms of mitigation can be used to reduce the impact of debris torrents on creek crossings and neighbouring residents. Passive mitigation methods include avoidance of the area, relocation of structures and facilities, land use restrictions, and some form of warning system. Active mitigation methods include remedial measures to remove or counter the causes, and various forms of designed protection. Constructing check dams near the headwaters of the creek and stabilizing the valley slopes that border the creeks are examples of remedial measures. Constructing debris barriers or clear span bridges with adequate clearance are examples of designed protection.Howe Sound, north of Vancouver, British Columbia, has had a relatively high number of debris torrents. Recently, several major studies have addressed the extent of the hazard and recommended mitigative measures for this area. Many of the examples presented in this paper are drawn from this case history. Key words: debris flows, debris torrents, slope stability, Southern Canadian Cordillera, Howe Sound, geological process, design considerations.

Abstract. Debris flows represent a major threat to infrastructure in many regions of the Alps. Since systematic acquisition of data on debris-flow events in Switzerland only started after the events of 1987, there is a lack of historical knowledge on earlier debris-flow events for most torrents. It is therefore the aim of this study to reconstruct the debris-flow activity for the Reuse de Saleinaz and the La Fouly torrents in Val Ferret (Valais, Switzerland). In total, 556 increment cores from 278 heavily affected Larix decidua Mill., Picea abies (L.) Karst. and Pinus sylvestris L. trees were sampled. Trees on the cone of Reuse de Saleinaz show an average age of 123 years at sampling height, with the oldest tree aged 325 years. Two periods of intense colonization (the 1850s–1880s and the 1930s–1950s) are observed, probably following high-magnitude events that would have eliminated the former forest stand. Trees on the cone of Torrent de la Fouly indicate an average age of 119 years. As a whole, tree-ring analyses allowed assessment of 333 growth disturbances belonging to 69 debris-flow events. While the frequency for the Reuse de Saleinaz study site comprises 39 events between AD 1743 and 2003, 30 events could be reconstructed at the Torrent de la Fouly for the period 1862–2003. Even though the two study sites evince considerably different characteristics in geology, debris-flow material and catchment morphology, they apparently produce debris flows at similar recurrence intervals. We suppose that, in the study region, the triggering and occurrence of events is transport-limited rather than weathering-limited.

Abstract. Debris flows have been recognized to be linked to the amounts of material temporarily stored in torrent channels. Hence, sediment supply and storage changes from low-order channels of the Manival catchment, a small tributary valley with an active torrent system located exclusively in sedimentary rocks of the Chartreuse Massif (French Alps), were surveyed periodically for 16 months using terrestrial laser scanning (TLS) to study the coupling between sediment dynamics and torrent responses in terms of debris flow events, which occurred twice during the monitoring period. Sediment transfer in the main torrent was monitored with cross-section surveys. Sediment budgets were generated seasonally using sequential TLS data differencing and morphological extrapolations. Debris production depends strongly on rockfall occurring during the winter–early spring season, following a power law distribution for volumes of rockfall events above 0.1 m3, while hillslope sediment reworking dominates debris recharge in spring and autumn, which shows effective hillslope–channel coupling. The occurrence of both debris flow events that occurred during the monitoring was linked to recharge from previous debris pulses coming from the hillside and from bedload transfer. Headwater debris sources display an ambiguous behaviour in sediment transfer: low geomorphic activity occurred in the production zone, despite rainstorms inducing debris flows in the torrent; still, a general reactivation of sediment transport in headwater channels was observed in autumn without new debris supply, suggesting that the stored debris was not exhausted. The seasonal cycle of sediment yield seems to depend not only on debris supply and runoff (flow capacity) but also on geomorphic conditions that destabilize remnant debris stocks. This study shows that monitoring the changes within a torrent's in-channel storage and its debris supply can improve knowledge on recharge thresholds leading to debris flow.

Abstract. On 7 August 2010, catastrophic debris flows were triggered by a rainstorm in the catchments of the Sanyanyu and Luojiayu torrents, Zhouqu County, Gansu Province northwestern China. These two debris flows originated shortly after a rainstorm with an intensity of 77.3 mm h−1 and transported a total volume of about 2.2 million m3, which was deposited on an existing debris fan and into a river. This catastrophic event killed 1765 people living on this densely urbanised fan. The poorly sorted sediment contains boulders up to 3–4 m in diameter. In this study, the geomorphological features of both debris flow catchment areas are analyzed based on the interpretation of high-resolution remote sensing imagery combined with field investigation. The characteristics of the triggering rainfall and the initiation of the debris flow occurrence are discussed. Using empirical equations, the peak velocities and discharges of the debris flows were estimated to be around 9.7 m s−1 and 1358 m3 s−1 for the Sanyanyu torrent and 11 m s−1 and 572 m3 s−1 for the Luojiayu torrent. The results of this study contribute to a better understanding of the conditions leading to catastrophic debris flow events.

Assim, o objetivo central deste estudo foi analisar a morfometria da bacia hidrográfica do Rio Verdinho, que possui uma área de 154.430,19 ha. Essa unidade hidrográfica é importante fonte de água para o desenvolvimento econômico e social do município de Rio Verde, Sudoeste de Goiás. O estudo foi realizado com uso de modelos matemáticos, produtos de sensoriamento remoto e técnicas de geoprocessamento. A área de estudo apresenta variáveis morfométricas, que associadas às formações geológicas, aos solos e à precipitação pluviométrica, são predominantemente favoráveis à conservação e à recarga de água desse sistema. Porém, a forma alongada e possíveis ocorrências de chuvas intensas na cabeceira sujeitam essa unidade hidrográfica às torrentes eventuais, podendo causar prejuízos ambientais, econômicos e outros no trecho médio e baixo da bacia; a amplitude altimétrica máxima, as maiores declividades, a densidade hidrográfica, densidade de drenagem, a presença, em menor percentual, de Argissolo Vermelho, Neossolo Litólico e Nitossolo Vermelho são favoráveis à perda de solos. Os resultados indicam que as ações antrópicas na área de estudo devem contemplar manejo e práticas conservacionistas do solo. Esses resultados subsidiarão o planejamento e à gestão ambiental desse recurso, além de servir de base para outros trabalhos em âmbito local e de outras regiões, contribuindo para a conservação da água em quantidade e qualidade adequadas para os diferentes usos.

This water unit is an important water source for the economical and social development of the municipality of Rio Verde, Southwest of Goiás. The study was accomplished with the use of mathematical models, products of remote sensing and geoprocessing techniques. The study area presents morphometric variables which, associated to geological formations, to soils and rainfall, are predominantly favorable to the water conservation and recharge of this system. However, the elongated shape and possible occurrence of intense rainfall in the river head subject this watershed to eventual torrents, being able to cause environmental and economic damages and others in the mid and lower watershed positions; the maximum altimetric amplitude, the biggest slopes, water density, drainage density, the presence, in a lowest percentage, of Red Argisol, Litholic Neosol and Red Nitosol are favorable to soil loss. The results indicate that the anthropic actions in the study area must contemplate management and conservationist practices of the soil. These results will subsidize the planning and environmental management of this water resource, besides serving as a base to other operations locally and in other regions, contributing to the preservation of the water in quantity and proper quality for different uses.Keywords: Geotechnologies; Mathematical Models; Water Resources

Abstract. The main goals of this study were to identify the alpine torrent catchments that are sensitive to climatic changes and to assess the robustness of the methods for the elaboration of flood and debris flow hazard zone maps to specific effects of climate changes. In this study, a procedure for the identification and localization of torrent catchments in which the climate scenarios will modify the hazard situation was developed. In two case studies, the impacts of a potential increase of precipitation intensities to the delimited hazard zones were studied. The identification and localization of the torrent and river catchments, where unfavourable changes in the hazard situation occur, could eliminate speculative and unnecessary measures against the impacts of climate changes like a general enlargement of hazard zones or a general over dimensioning of protection structures for the whole territory. The results showed a high spatial variability of the sensitivity of catchments to climate changes. In sensitive catchments, the sediment management in alpine torrents will meet future challenges due to a higher rate for sediment removal from retention basins. The case studies showed a remarkable increase of the areas affected by floods and debris flow when considering possible future precipitation intensities in hazard mapping. But, the calculated increase in extent of future hazard zones lay within the uncertainty of the methods used today for the delimitation of the hazard zones. Thus, the consideration of the uncertainties laying in the methods for the elaboration of hazard zone maps in the torrent and river catchments sensitive to climate changes would provide a useful instrument for the consideration of potential future climate conditions. The study demonstrated that weak points in protection structures in future will become more important in risk management activities.

Abstract. Heavy precipitation can mobilize tens to hundreds of thousands of cubic meters of sediment in steep Alpine torrents in a short time. The resulting debris flows (mixtures of water, sediment and boulders) move downstream with velocities of several meters per second and have a high destruction potential. Warning protocols for affected communities rely on raising awareness about the debris-flow threat, precipitation monitoring and rapid detection methods. The latter, in particular, is a challenge because debris-flow-prone torrents have their catchments in steep and inaccessible terrain, where instrumentation is difficult to install and maintain. Here we test amplitude source location (ASL) as a processing scheme for seismic network data for early warning purposes. We use debris-flow and noise seismograms from the Illgraben catchment, Switzerland, a torrent system which produces several debris-flow events per year. Automatic in situ detection is currently based on geophones mounted on concrete check dams and radar stage sensors suspended above the channel. The ASL approach has the advantage that it uses seismometers, which can be installed at more accessible locations where a stable connection to mobile phone networks is available for data communication. Our ASL processing uses time-averaged ground vibration amplitudes to estimate the location of the debris-flow front. Applied to continuous data streams, inversion of the seismic amplitude decay throughout the network is robust and efficient, requires no manual identification of seismic phase arrivals and eliminates the need for a local seismic velocity model. We apply the ASL technique to a small debris-flow event on 19 July 2011, which was captured with a temporary seismic monitoring network. The processing rapidly detects the debris-flow event half an hour before arrival at the outlet of the torrent and several minutes before detection by the in situ alarm system. An analysis of continuous seismic records furthermore indicates that detectability of Illgraben debris flows of this size is unaffected by changing environmental and anthropogenic seismic noise and that false detections can be greatly reduced with simple processing steps.

We analysed the lifecycle of content shared using the BitTorrent network, focusing on torrents retrieved by mobile phone clients using our MobTorrent application. MobTorrent, a complete Bit-Torrent client for feature phones, enables anonymous usage statistics to be collected. Based on statistics collected over the last three years, we analyze how mobile BitTorrent clients are being used. We discuss the success of individual sessions by additionally measuring peer connection download and success ratio statistics.

Protection of land with vegetation is the primary factor in the fight against water erosion with necessary application of biotechnical, technical, administrative and planning measures. One of the first basins to be treated with works for the protection against erosion and torrent control is the Gradasnica River basin. The basic parameters to display the changes of the hydrological status of the land are the state of erosion, the change of erosion-coefficient, annual sediment yield, specific annual sediment discharge through the hydrographic network, the value of the runoff curve number and value of the maximal discharge. Works on protection from erosion and regulations of torrents have influenced the decrease in erosion coefficient values from strong erosion (Z=0.99) to the value of weak erosion (Z=0.40), as well as the reduction of the maximum discharge value from Qmax(1956)=108,12m3/s to the value of Qmax(2014)=87.2 m3/s.

Abstract. Debris flows generally propagate along steep mountain torrents with dynamics primarily governed by gravitational and frictional forces. Thus, debris flows modelling can be successfully performed through the application of kinematic models, which consider only the effects of slope and friction and neglect the remaining terms of the momentum equation. However, the diffusion processes that can be observed in the field, such as the spreading of the debris flow wave as it flows downstream, can not be theoretically predicted by kinematic models, since diffusion is a second-order process neglected in the kinematic approximation. In this paper, this issue is discussed and an application for both a generalized diffusion wave model and a kinematic model is proposed of a debris flow which occurred in an Italian instrumented torrent to identify, in a real case scenario, the effective value of the neglected terms in the kinematic approximation.

In the current era of quantity theorists and inconvertible currencies, the real bills doctrine has received a surprising amount of recent attention (e.g., Sargent and Wallace, 1982; Smith, 1988; Selgin, 1989; Cunningham, 1992). While the real bills doctrine has a long history, the doctrine underwent considerable evolution during the period from the Bullionist debates of the Restriction Period, 1797–1819, to the Banking School versus Currency School debates surrounding the introduction of Peel's Act in 1844. The debates of the Restriction period are significant for being directly concerned with the workings of an inconvertible, real-bills-based paper currency while the later debates involved the real bills doctrine under convertibility. A primary objective of this paper is to explore the views that Robert Torrens held concerning the inconvertible and convertible versions of the real bills doctrine as a rule for central bank policy. Torrens's contributions as an anti-bullionist and, later, as a leading member of the Currency School reflect the importance that both convertibility and bank lending practices have for interpreting the real bills doctrine and the related law of reflux. The apparently paradoxical evolution of Torrens's monetary thought identified by Lionel Robbins (1958) is attributed primarily to the evolution of his views on bank lending practices.

This paper is devoted to the results of our issues exploration increasing efficiency action in extreme circumstances. Long time we study only combat oriented activities but now it is obvious that work with information torrents has the same features of stress as a fight. Our exploration was based on Oleg Bakhtiyarov ideas who study deconcentration of attention phenomenon. We adapted these ideas and combined traditional for our country approaches to hand-to-hand combat and special software. We used two main ideas for experiments. The first one was searching for hidden threats and stealthy attacks with deconcentration and after that was concentration attention on threats and destroying them. This gave us only part-time at deconcentration. We used “plane deconcentration” for searching and “multidimensional deconcentration” for action. The second idea was about using deconcentration for avoiding dangerous situations. That case was about full-time deconcentration. We discovered two types of usage deconcentration indirect or without direct contact with attackers but not only this feature and we need to explore it in the future. We discovered the same features in combat activities and works with information torrents. In addition, the same features were discovered between our data and the other from e-sports. In addition, the same features were discovered between our data and the other from e-sports. All of that gives us opportunities to use the deconcentration of attention methods for tasks that are needed for operators and common people in the information society (searching, detection, distinguishing, and filtration of information torrent) and, of course, for mental hygiene goals.
