Texto completoTerrestrial laser scanning (TLS) is based on lidar technology, which although developed in the early 1960s, has only recently been incorporated into the study of geological outcrops. The main aim of this thesis is to take advantage of the potential of the TLS to provide new tools and methodologies focused on solving the main limitation found by the geologists when working in fluvial outcrops: acquire the degree of stratigraphic control required to detect, understand and characterize the high degree of spatial and temporal heterogeneity of fluvial successions. TLS data from 8 outcrops of the Huesca Fluvial Fan (Early Miocene, northern Spain) were acquired to this purpose. In addition, several detailed stratigraphic columns were measured and lithological samples from different types of sandstone bodies were collected. Based on this, the most relevant results obtained are as follows: * A comprehensive characterization of the fluvial facies that includes the petrological and petrophysical properties of the sandstone bodies. * A simple method using the VO to correct the heights and thicknesses of the sedimentary bodies measured in the stratigraphic columns. The main factors that may have influenced the measurements made with the Jacob’s staff have been studied and discussed. * A new method leading to obtain a virtual datum is presented in response to the need for further correlation procedures, especially in the absence of suitable datums. This virtual datum enables to achieve highly accurate and semiautomatic correlations within fluvial VO’s. Moreover, all the sedimentary successions of the outcrops can be automatically subdivided into the desired stratigraphic intervals (which can be later isolated) by only moving the virtual datum vertically. * The virtual datums were also used to establish a new procedure that leads to infer the relative stratigraphic positions of distant outcrops (more than 10 Km apart) inside the entire fluvial sequence. * A facies modelling has been performed using a new method to extract in a semiautomatic way the surfaces of the outcrop that belong to paleochannel exposures.

Texto completoThe present study aims to provide a solid background for river-floodplain restoration based in the response of aquatic communities, to changes in hydrological connectivity, environmental factors and human pressure across the floodplain of a Mediterranean river.The lateral hydrological connectivity was found to be the key factor structuring the habitats and aquatic communities of the Middle Ebro floodplain, while turbidity, salinity and nutrient status were secondary drivers. These factors created a template for the aquatic community development that enabled predictions about the taxonomic and functional patterns in those aquatic communities more likely to occur under particular conditions. In the Middle Ebro River, there are very few possibilities of new wetlands creation, while the diversity and functionality of the remaining ones are threatened by the limited hydrological connectivity. The objective of floodplains restoration should thus consist in re-establishing a wide range of wetland types in accordance with the river-floodplain potential of sustainability.

Texto completo"Diatoms of the Ebro basin: Biodiversity and ecological state of water" TEXT: The aim of this PhD thesis is to contribute to the taxonomic knowledge of the epilithic diatom flora from the rivers of the Ebro basin and to determinate the water quality status in the studied area using benthic diatoms as indicators. The studied area is located inside the Water Quality Surveillance Network of the Ebro Water Agency, CHE (NE Spain). It includes the Ebro and Garona rivers and all the rivers and streams which run into them in the Spanish territory, mostly over a calcareous and sedimentary substrata. A total of 408 epilithic diatoms samples were collected from different environments and ecoregions within the limits of the network of the Ebro Water Agency, CHE (NE Spain) during the summers of 2005 (197 sites) and 2006 (211 sites). Epilithic diatom were sampled, and then treated to prepare permanent diatoms slides following the standard methods (European Committee for Standardization 2003, 2004). The number of taxa identified in the material studied amounted to 499 (492 a specific or infra specific level), belonging to 91 different genera. 361 taxa are presented in 751 light microscope micrographs regrouped in 25 plates. We noticed the presence of species considered rare or exotic for European freshwaters (Coste & Ector, 2000) such as Diadesmis confervacea; Achnanthidium catenatum, Reimeria uniseriata, Navicula kotschyi, Gomphoneis minuta and Didymosphenia geminata. A few diatoms species presented teratological forms have been detected in some localities. However, we could not find a direct relationship of these forms occurrence and any particular cause. In order to evaluate the water quality assessment, three diatoms indices were applied (Specific Pollution Index IPS, Biological Diatom Index BDI and European Index CEC). All of them correlated significantly with water physical and chemical variables, but SPI achieved better correlations, and is therefore to be the best diatom index to be applied in the Ebro basin, although in some cases it did not properly reflected special situations in this basin as calcareous headwaters. According to the cluster and canonical correspondence analyses, nutrient enrichment (from the headwaters to the mouth), environmental variables and impacts were to be the most important variables structuring diatom communities in the Ebro basin.

Texto completoEl Delta de l’Ebre representa l’àrea humida més important de Catalunya, la segona àrea més important d’Espanya (després del Parc Nacional de Doñana) i una de les zones estuarines més importants d’Europa. Tot i la seva recent colonització humana, està considerat com una àrea fortament impactada. El principal objectiu de la present tesi doctoral va ser avaluar els efectes de dues de les activitats humanes dutes a terme a les llacunes costaneres del Delta de l’Ebre: les pesqueries artesanals i la gestió de l’aigua. A més a més, aquest estudi ha permès investigar l’actual condició de la comunitat piscícola (tant a nivell de composició com d’estructura), desconeguda durant les últimes dècades. Tres objectius específics sota l’objectiu general van ser assolits: (i) estudiar la selectivitat de malla de les xarxes ganyeres i la seva possible aplicació com a eines de gestió en combinació amb estudis de maduresa sexual; (ii) construcció d’un model tròfic per tal d’avaluar l’impacte global de les pesqueries artesanals en l’ecosistema i (iii) analitzar l’impacte de la gestió de l’aigua derivada del cultiu d’arròs a la zona. El conjunt de resultats obtinguts en aquesta tesi doctoral posen de manifest: (i) la inadequació de l’actual sistema de gestió de les pesqueries artesanals pel que respecta l’espècie vulnerable Atherina boyeri. L’enfocament seguit de combinar els estudis de selectivitat de malla amb els estudis de maduresa sexual varen ser d’utilitat per establir noves mesures de gestió per a l’espècie; (ii) una disminució gradual de l’esforç pesquer com la millor estratègia de gestió, assegurant conjuntament la sostenibilitat de la pesca i la conservació de les llacunes costaneres del Delta de l’Ebre i (iii) l’actual esquema de gestió de l’aigua a les llacunes costaneres ha causat la inversió del cicle hidrològic, ha augmentat la presència d’espècies d’aigua dolça (majoritàriament espècies introduïdes) i ha alterat la composició d’espècies de la comunitat piscícola.

Texto completo"Els parlars del Baix Ebre. Estudi geolingüístic" es una investigación que describe el catalán de cada una de las poblaciones del Baix Ebre. En el marco de la dialectología, y desde el punto de vista de la geolingüística, los datos registrados a través de la encuesta dialectológica pasada a diversos informantes de cada población sirven para analitzar la llengua catalana coloquial de la comarca. Los resultados se organizan y presentan en los diferentes niveles lingüísticos: fonética, morfología, sintaxis i léxico. Aparte de la descripción de las hablas del Baix Ebre en su totalidad, los objetivos fundamentales de la investigación han sido establecer las relaciones y paralelismos lingüísticos existentes entre las diferentes hablas, determinar las áreas dialectales intracomarcales y precisar la classificación dialectal del catalán de la comarca. Por otro lado, las características que han sido descritas en los cuatro niveles lingüísticos nombrados, y que reflejan la variación interna de la comarca, se representan cartográficamente a través de un total de 1209 mapas. Este corpus de mapas constituye el "Atles Lingüístic del Baix Ebre" (ALBE), que pone en evidencia la variación lingüística del Baix Ebre, teniendo en cuenta su situación central en el bloque occidental de la llengua catalana. Además de la introducción, la metodología, una descripción geográfica y histórica de la comarca y un apartado en el que se presentan los estudios lingüísticos previos referentes al Baix Ebre, completan el trabajo un listado alfabético de todas las palabras recogidas en el nivel léxico y un anejo con un etnotexto de cada población, como ejemplo del habla coloquial de cada una de las veintitrés localidades de la comarca.
"Els parlars del Baix Ebre. Estudi geolingüístic" is a research assignment meant to make a proper description of the Catalan dialect spoken in each of the towns and villages in the Baix Ebre County Council. Keeping in mind both dialectology and geolinguistics, all data were gathered by means of surveys to people from each community, whose given information has been properly used to analyse the colloquial speeches of the region. The final results have been organised and presented according to several different language levels, such as: phonetics, morphology, syntax and vocabulary. In addition to the proper description of the Baix Ebre dialect as a whole, the main objectives of our research were to settle the existing parallels and linguistic relationship among the different speeches in order to determine the different dialectal areas and, mainly, specifying its dialectal classification of this regional Catalan. The main features described in the four linguistic levels mentioned above, which are mirroring the region's inner variation, have been properly mapped by means of 1209 maps. All these maps have constituted the "Atles Lingüístic del Baix Ebre" (ALBE), in which the linguistic variation in the Baix Ebre region has been recorded, taking into account its central location in the frame of the Western bloc of the Catalan language. To begin the assignment, an introductory preface, methodology and a proper geographical and historical description of the region have been presented. It also includes a section to mention the previous linguistic studies regarding the Baix Ebre region and an alphabetical list with all the words contained (lexical richness). Finally, you will find an outstanding annex with an ethnographic text from each town or village. These are proper samples of the colloquial speech of each of the twenty-three localities (municipalities and also villages) of the region.

Texto completoThe Ebro Delta is one of the largest in the Iberian Peninsula and the Mediterranean sea. The Fangar bay, focus of this study is about 12Km2 with depth values ranging between 0 and 8 meters. Displays of fresh water from irrigation canals in the delta waters belonging to rice fields (inputs that are influenced and / or dependent cycle of rice cultivation). In addition there are contributions from some brackish lagoons, water from rain, groundwater and water exchange of oceanic origin. The characteristics of water bodies and their dynamics throughout the year in the bay, are very important to explain the possibilities of growing and the most suitable techniques for their management. We seek to contribute at knowledge and a better understanding of the behavior of the bay, linking biotic and abiotic factors measured, with the help of statistical tools and current models. During the period October 1986 to November 1987 were sampled monthly at three points of the bay's Fangar, distributed in parallel to the coast three stations were chosen as representative points in the bay (mouth, middle and bottom Bay), where one of them matches the aquaculture of bivalve molluscs present in this area. All stations were sampled to 3 levels deep: at 30 cm depth (surface), another intermediate level at 2 m (middle), and at 4 m (bottom). The samples consisted of direct measurement of parameters such as temperature, salinity, oxygen in the stations and depths established, and collect sea water samples for analysis in the field and in the laboratory for nitrates, nitrites, ammonium, phosphate , chlorophyll a, b and c, phaeopigments, particulate carbon and nitrogen, protein, carbohydrates and particles. We found strong seasonal changes in the bay, both natural origin and anthropogenic (rice, aquaculture activities, etc.). We found the great importance of the contributions of dissolved inorganic nutrients in freshwater from the drainage channels of rice fields to the bay. In this appearance, the Fangar bay would be a very singular and unique. The bay would behave like an estuary, with periods of very dynamic and others more static, these deviations would be given by freshwater inputs, as well as meteorological and oceanographic factors in the different seasons. Changes were studied throughout the year under the conditions of salinity and temperature, nutrients and biomass, which is more pronounced compared to those observed at open sea, confirming a dynamic. The tiem residence in the bay during some periods range between 3 and 6 days, when the influences of weather or tidal type are minimal. We propose mixed models for the oscillations of the parameters chlorophyll-a and "total chlorophyll" which are statistically robust and that provide insight into the relationships between biotic and abiotic parameters measured in the bay and explain the variations of chlorophyll-a and "total chlorophyll”. The study provides important ecological knowledge and the dynamics of the bay, and for management improvements and shellfish culture that develops in the area.

Texto completoThe zebra mussel, Dreissena polymorpha (Pallas, 1771), is known to be one of the worst freshwater invasive species worldwide. This successful invasive bivalve is native to the Ponto-Caspian region and has been introduced throughout Europe and North America. It was first discovered in the Iberian Peninsula in the lower Ebro River in 2001. Since its invasion the zebra mussel has spread throughout most of the Ebro river basin and other catchments of the Iberian Peninsula. The high ecological and economical impacts caused by the zebra mussel have promoted the study of this specie. In the case of the Ebro river basin studies are still scarce. The present PhD thesis focuses on the study of zebra mussel populations established in the lower Ebro River, between the Mequinenza reservoir (Zaragoza) and the beginning of the estuarine area (Tarragona). Throughout the present study information on the structure, distribution patterns and population dynamics of the zebra mussel present in the Mequinenza, Ribarroja and Flix reservoirs, was obtained for a full year. Planktonic and sessile larval stages were studied, and their relationship with reservoirs’ environmental variables were analyzed. Most studies on the zebra mussel are focused on lentic systems, such as reservoirs or lakes, where populations reach higher densities. However, the habitat preferences of this species in lotic systems are poorly known. Therefore, in this PhD thesis the relationship between environmental and water physicochemical parameters and the abundance and distribution of the zebra mussel in the lower Ebro River, from the Flix reservoir to the limit of the salt wedge was assessed. Moreover, the filtration rate of the zebra mussel inhabiting this river stretch was calculated. This parameter was determined because of its importance in both the zebra mussel populations’ auto regulation and the potential effects on colonized water bodies. Finally, a population dynamics model to simulate the zebra mussel abundance over time was developed. The construction of this model was performed with both bibliographic information and own data generated in the present PhD thesis.

Adolescence is legally identified in Brazil as a period between 12 and 18 years of age, which are experienced biopsychosocial level transformations. If adolescents present behavior in conflict with the law, educational measures may be applied in open or closed. Monitoring the family and adolescent in the fulfillment of socio-educational measures amid open to provide Services to the community and Assisted Freedom takes place through the Centro de Referência Especializado de Assistência Social (CREAS). The present research is characterized as descriptive, qualitative measures, and aimed to assess the parental style and food insecurity of seventeen families of teenagers in fulfillment of socio-educational measure on the CREAS of County of Dois Vizinhos, State of Paraná, considering these as factors that promote impacts on regional development and in the performance of public policies. The application of Parental Styles inventory to teens and their mothers, and in these, the implementation of Escala Brasileira de Insegurança Alimentar (EBIA) to know the percentage of food insecurity of these families. The results show that teens have assessed their mothers with a below-average parenting style in ten cases (58.8%), it was noted in the assessment of mothers about their own conduct. On average between the results of teenagers and mothers compared, only one family (5.9%) achieved great result, five families (29.4%) were classified as at risk, and four families (23.5%) in regular situation. Applying the Wilcoxon test identified that the answers of the adolescents and their mothers in relation to parental style did not show significant variation, with exception to the moral behavior, where there was no difference between the perception of the teenagers and their mothers. The results of the application of EBIA pointed to the existence of 24% of the surveyed families in situation of food security. Mild food insecurity was observed in 24% of households, moderate for 35% of families and serious in 17% of families surveyed. The degrees of food insecurity are high compared to other samples of the population, however, no similar studies have been found. Identifies this way parental style and food insecurity are variables that make up the framework of vulnerability to which are subjected teenagers in conflict with the law, requiring the joint performance of public policies to overcome the hazard identified
A adolescência é legalmente identificada no Brasil como um período entre os 12 e os 18 anos de idade no qual são vivenciadas transformações a nível biopsicossocial. Caso o adolescente apresente comportamento em conflito com a lei, podem ser aplicadas medidas socioeducativas em meio aberto ou fechado. O acompanhamento da família e do adolescente em cumprimento de medida socioeducativa em meio aberto de Prestação de Serviços à Comunidade e Liberdade Assistida se dá através do Centro de Referência Especializado de Assistência Social (CREAS). A presente pesquisa caracteriza-se como descritiva, de cunho qualitativo, e teve como objetivo avaliar o estilo parental e a insegurança alimentar de dezessete famílias de adolescentes em cumprimento de medida socioeducativa no CREAS do município de Dois Vizinhos, estado do Paraná, considerando estes como fatores que promovem impactos no desenvolvimento regional e na atuação das políticas públicas. Foi realizada a aplicação do Inventário de Estilos Parentais aos adolescentes e às suas respectivas genitoras, e nestas, a aplicação da Escala Brasileira de Insegurança Alimentar (EBIA) para conhecer o percentual de insegurança alimentar destas famílias. Os resultados apontam que os adolescentes avaliaram suas mães com um estilo parental abaixo da média em dez casos (58,8%), o mesmo foi observado na avaliação das mães sobre suas próprias condutas. Na média entre os resultados dos adolescentes e das genitoras comparados, apenas uma família (5,9%) alcançou o resultado ótimo, cinco famílias (29,4%) foram classificadas como de risco, e quatro famílias (23,5%) em situação regular. A aplicação do teste de Wilcoxon identificou que as respostas dos adolescentes e de suas genitoras em relação ao estilo parental não apresentaram variação significativa, com exceção à variável de comportamento moral, a qual houve diferença entre a percepção dos adolescentes e de suas genitoras. Os resultados da aplicação da EBIA apontaram para a existência de 24% das famílias pesquisadas em situação de segurança alimentar. A insegurança alimentar leve foi observada em 24% das famílias, moderada para 35% das famílias e grave em 17% das famílias pesquisadas. Os graus de insegurança alimentar são elevados se comparados a outras amostras da população, todavia, não foram encontrados estudos semelhantes. Identifica-se desta forma que o estilo parental e a insegurança alimentar são variáveis que compõem o quadro de vulnerabilidade ao qual estão submetidos os adolescentes em conflito com a lei, demandando a atuação conjunta das políticas públicas para a superação das situações de risco identificadas.

Texto completoResearch has its origin in two main worries. On the one hand, the concern about upgrading language and literature teaching approaches and on the other hand, the will to contribute to strengthen the process of formation of the Ebre area literature and the inclusion of literary productions related to the Ebre lands into the language and literature curriculum. The fact that referring to literary works from our area in class increases the students concern about the subject is an evidence that I have experienced along my career as a teacher of Catalan language and literature, but there are few mentions to them and no research or syllabus design to support the prosecution of this project. In the previous years, every new step in the didactics of literature has been turning into a historicist knowledge repertoire, into isolated literary comments or text writing or into a textual typology depending on grammar and language rules, which has made us feel the need to promote and focus in a new literary teaching approach based on productions of literature from authors nearby. Our project comes from an analysis that takes us to the theory of complexity as a perspective to define a reflective practice method supported by constructivist contributions which is linked to the cultural geography and the didactics of heritage as disciplines that help us design our plan. The main goal is basing a proper practice of literary education while we approach the literary fact and studies -literary theory, review and comparative literature- to see and outline those models that can contribute as supporting elements in a didactics of literature that aims the development of educational teaching. Considering all these, we lay out the perspective of localised literature, work on an educational system of the intertext reading from several didactic proposals and we analyze and assess them throughout a qualitative based methodology that provides us reflection on the prosecution and modulation of our project.

Texto completoToday's Swedish power grid has a major need for renovation and upgrading, which gives a big investment requirement over the next few years. This makes it important to find new entrepreneurs in addition to those already available today. Find a way to become more attractive and interesting for these entrepreneurs. This report highlights two methods that outsourcer have to relate to. First method is Electrical Building Rationalization (EBR) and the other method is general material and work description (AMA). The system of EBR is a secure system based on long-term statistics from installations, renovations and maintenance. There the advantages of standardized components are that they are cost-effective and create a quality of work performed. AMA is a reference tool for building projects from scratch. It's freer in its structure when planning a facility. One does not need relate to more strict approach. This report looks at the differences in EBR / AMA and looks at what are good changes to attract new actors in the market.

Texto completoThe Ebro delta, the third largest delta in the Mediterranean Sea, is a site of high economic and environmental impact, and with a variety of wetlands. In this thesis we have collected the most representative Peracarida species with stable populations in the Delta, with the aim of studying the life cycle for almost two years. The species selected to perform this work were following: Mesopodopsis slabberi, Hemimysis lamornae mediterranea, Gammarus aequicauda, Ericthonius brasiliensis and Monocorophium insidiosum. We studied the annual evolution of these populations, reproductive cycle, demography, sex-ratio fecundity and the significant sizes, among other population parameters. It has been shown that the longevity of individuals changes throughout the year. The winter generation shows larger sizes and longer lifespan while summer generations display smaller size and less longevity. The species studied are iteroparous and multivoltines and the size of the female is related to the number of eggs and in the two Mysida species also related to the size of eggs. Females of all species show an annual average size that matches with the minimum size of the female ovate in winter and the maximum size ovate in summer. Furthermore the eggs size keeps an inverse relationship with temperature (except in Ericthonius brasiliensis), such that winter females produce larger juveniles, with more survivability. Growth and reproduction in the laboratory allowed us to complete information about the ecological and reproductive strategy to Hemimysis lamornae Mediterranea and Gammarus aequicauda. So we studied the influence of salinity on the growth and reproduction of Gammarus aequicauda, with or without previous acclimatization, and it has been shown that this species can grow in a wide range of salinities, from 40 to 2 PSU For Hemimysis lamornae mediterranea (first record on the Iberian Peninsula), the average of incubation time (intramarsupial stages) in laboratory conditions was 11 days (20° C) and sexual maturity reached between 14 and 20 days. The growth rate is faster in youth stages, declines with age, showing a maximum of 0.152 mm per day.

CAPES
O Brasil conta na atualidade com marco legal para a promoção e garantia da Segurança alimentar e nutricional - SAN, integrando a criação do sistema de segurança alimentar – SISAN em todos os níveis de governo e a política nacional de SAN. O desafio de construir um sistema de SAN municipal envolve informações e conhecimento sobre a situação a ser enfrentada e seus determinantes, e estes são geralmente deficientes ou inexistem em municípios menores. No Brasil, por outro lado, há uma tendência de focalizar os territórios no enfrentamento de problemas sociais, entendendo-se ser esta uma forma de promover maior impacto na alteração das condições de vida das pessoas. A criação dos Consórcios de Segurança Alimentar e Desenvolvimento Local – CONSADs atende a este objetivo. Este estudo, avaliou a situação de segurança alimentar e seus determinantes em municípios baianos integrantes do CONSAD Vale do Jiquiriçá, contemplando uma metodologia direta, pela aplicação em domicílios da Escala Brasileira de Insegurança Alimentar – EBIA e de um questionário sócio-econômico. A amostra domiciliar constituiu-se de 2.002 domicílios, em oito municípios do CONSAD. Encontrou-se insegurança alimentar em 70,3% dos domicílios, com predomínio da insegurança grave e moderada (36,0%). A IA mostrou-se fortemente associada as variáveis, renda familiar per capita, número de moradores por domicílios, indicador ambiental. Conclui-se que com as avaliações realizadas compôs-se um quadro capaz de orientar a ação pública na direção da SAN de uma forma geral, para todo o município, e considerando as condições de vida nos domicílios particulares, conformando também uma base para o desenho do SISAN e possibilitando o acompanhamento e avaliação do realizado.

Texto completoEls efectes dels principals impactes antropogènics de l'ecosistema fluvial del tram baix del riu Ebre s'estudien al llarg dels cinc capítols d'aquesta tesi, utilitzant la comunitat de macroinvertebrats bentònics com a bioindicadors. Depenent del tipus d'estrès, tenint en compte principalment la contaminació per metalls pesants i organoclorats i les alteracions hidrològiques, s'han considerat diferents aproximacions. Concretament, l'estudi se centra en la taxonomia i els trets biològics de la comunitat, la bioacumulació de contaminants, i els estudis poblacionals i relacionats amb el cicle biològic d'espècies clau com l'Ephoron virgo (Ephemeroptera: Polymitarcyidae). Els resultats evidencien una resposta ecològica important, i demostren que aquests efectes actuen a diferents nivells d'organització, incloent comunitats, poblacions i individus.

Texto completoEl principal procés en l'escenari a llarg termini que pot causar importants canvis en zones costaneres amb poca elevació (per exemple, el Delta de l'Ebre), és l'Elevació del Nivell del Mar. Degut a això, es reproduïxen tres escenaris d'elevació del nivell del mar per a determinar àrees potencialment inundables, tenint en compte el paper de les estructures interiors -com canals, dics i carreteres- en la prevenció d'inundacions.
L'escenari extrem o episòdic, s'associa a processos amb períodes de retorn molt amplis i que no presenten una periodicitat en el temps. En aquest cas, es van identificar les àrees inundables associades a tempestes costaneres amb períodes de retorn de 10, 50, 100 i 500 anys. Per a la determinació d'aquestes àrees, es va identificar la resposta morfodinámica de la costa i la distribució de la inundació a la part posterior de la platja.
Així mateix, es va dur a terme una avaluació dels danys i pèrdues associades a la inundació. Per a això es van emprar els valors dels serveis ecològics de l'ecosistema. I es va implementar un indicador de Vulnerabilitat Costanera a l'Erosió per Tempestes.
Esta tesis propone un marco metodológico para la determinacion de Areas con Riesgo a Inundaciones y la Evaluación de Daños por Tormentas Costeras, en dos escalas de trabajo: una a largo plazo relacionada con la Elevacion Relativa Nivel del Mar y una episódica/extrema relacionada con eventos de tormenta. La incorporación de la respuesta morfodinamica de la costa a eventos de tormenta es una parte fundamental de esta propuesta. Este marco metodológico fue aplicado en el Delta del Ebro.
El principal proceso en el escenario a largo plazo que puede causar cambios importantes en zonas costeras con poca elevación (por ejemplo, el Delta del Ebro), es la Elevación del Nivel del Mar. Por lo anterior, se reproducen tres escenarios de elevación del nivel del mar para determinar áreas potencialmente inundables, teniendo en cuenta el papel de las estructuras interiores -como canales, diques y carreteras- en la prevención de inundaciones.
El escenario extremo o episódico, se asocia a procesos con periodos de retorno muy amplios y que no presentan una periodicidad en el tiempo. En este caso, se identificaron las áreas inundables asociadas a tormentas costeras con periodos de retorno de 10, 50, 100 y 500 años. Para la determinación de estas àreas, se identifico la respuesta morfodinámica de la costa y la distribución de la inundación en la parte posterior de la playa.
Así mismo se llevo a cabo una evaluación de los daños y perdidas asociadas a la inundación. Para lo cual se emplearon los valores de los servicios ecológicos del ecosistema. Y se implemento un indicador de Vulnerabilidad Costera a la Erosión por Tormentas.
A methodological framework for Flood Hazard Mapping and Damage Assessment to Coastal Storms was proposed in this thesis in two working scales: A long-term scale related to Relative Sea-Level Rise, and an episodic/extreme scale related to storm events. The incorporation of coastal response to storm events in this framework is a basic part of this proposal. This methodological framework was aplied to the Ebro Delta.
In terms of the long term scale, the Relative Sea Level Rise is the main process that can cause important changes in low-lying coastal areas, such as Ebro Delta. Three possible scenarios of sea level rise were reproduced to determine potentially flood areas considering the paper of the inner structures - like channels, docks and highways - in the floods prevention.
The extreme/episodic scenario is associated to processes that have very large return periods and do not exhibit a periodicity in the time. Flood areas associated to coastal storms with return periods of 10, 50, 100 and 500 years were identified. For this aim, the coastal morphodynamic response and the backbeach flood distribution were studied.
Additionally, an evaluation of the lost and damages associated to flood was carry out. For this study, the values of the ecological services of the ecosystem were used. An indicator of Coastal Vulnerability to the Erosion by Storms was also implement.

Texto completoPara ensayar Ia aplicabilidad del método de balance de Ia deposición atmosférica de ion cloruro y del balance de agua en el suelo con el código Visual Balan para Ia estimación de Ia recarga media multianual se ha elegido el área de Ia Vall Baixa de I'Ebre. Se trata de un área costera de clima mediterráneo semiárido emplazada al noreste de Ia península Ibérica, entre Tortosa y Morella. El sistema acuífero es hidrodinámicamente complejo. Comprende Ia Plana de La Galera, entre los ríos Ebro y La Sénia, y parte de los Ports de Beseit-Tortosa , un elevado macizo montañoso carbonático. La precipitación media anual es de 550 mm .a-1 en Ia Plana de La Gal era y 11 00 mm .a-1 en los Ports de Beseit-Tortosa. Para refinar los resultados obtenidos mediante esos dos métodos se ha definido un modelo conceptual de funcionamiento a partir de Ia información geológica-hidrogeológica y con el apoyo de técnicas hiodrogeoquímicas e isotópicas ambientales del agua, considerando y evaluando el efecto que tiene Ia escorrentía superficial que s e produce en Ia zona montañosa. A partir de Ia definición del modelo hidrogeológico conceptual y del estudio global del funcionamiento hidrológico del macizo de los Ports de Beseit-Tortosa en todo su ámbito geográfico e hidrogeológico , mas alía de Ia zona del estudio (vertiente NW, cuenca del rio Matarraña) y vertiente SE, Plana de La Galera, ha sido posible hacer una estimación de Ia escorrentía superficial ocasional media que se produce obteniendo una magnitud de 105 ± 20 mm .a-1 en un periodo de 15 años de datos. La recarga media anual en el periodo de datos según el balance de agua en el suelo en Ia Plana de La Galera varia entre 215 y 240 mm .a-1, con una desviación estándar entre 20 y 25 mm .a-1, según Ia sub-zona, yes de 500 ± 60 mm .a-1 en los Ports de Beseit-Tortosa. El balance de Ia deposición atmosférica de ion cloruro en Ia Plana de La Galera proporciona valores de Ia recarga media multianual de 130-175mm .a-1 con una desviación estándar de 35-70 mm .a-1 yen los Ports de Beseit-Tortosa de 315-36 mm .a-1 con una desviación estándar de 150-160mm .a-1. Los coeficientes de variación se sitúan en torno al 0,1 para el balance de agua en el suelo yal 0,35 con el balance de Ia deposición atmosférica de ion cloruro. Con este coeficiente de variación los valores obtenidos por el balance de agua en el suelo están dentro del rango esperable de recarga media anual producida según el balance de Ia deposición de cloruros. La relación recarga-pluviometría es típica de climas semiáridos, con un umbral media de pluviometría para que exista recarga de 240-300 mm.a-1 en Ia Plana de La Galera y entre 56-108 mm.a-1 para los Ports de Beseit-Tortosa, lo que muestra una capacidad mayor de recarga en colas altas en años secos. La distribución anual y mensual de Ia recarga se concentra en los meses de octubre, diciembre, enero y mayo con máximos que reflejan que Ia ocurrencia de recarga se produce, en buena parte, debido a eventos de precipitación extraordinarios; el1% de las lluvias diarias de mayor magnitud produce el 70% de Ia recarga. Las entradas al sistema se estiman en unos 285 hm3.a-1 que es Ia suma de Ia recarga por precipitación, Ia recarga por escorrentía superficial y los retornos de riego. Las salidas por bornbeo y las descargas s subterráneas, tanto al margen derecho del rio Ebro como al Mar Mediterráneo en Ia franja literal de Ia Plana de Alcanar, han sido estimadas entre 120-320 hm3.a-1, estas últimas muy difíciles de cuantificar, pero que enmarcan bien Ia evaluación de Ia recarga.

Texto completoAquesta tesi estudia l'impacte que les plantes clor-àlcali de Flix i Montsó han tingut en el tram baix de la conca del riu Ebre. Primerament avalua la dispersió atmosfèrica dels contaminants emesos a Flix. En segon lloc estudia la mobilitat dels sediments contaminants dipositats a l'embassament de Flix aigües avall del riu i l'impacte en l'activitat agrícola d'aquest tram de riu. Finalment caracteritza els residus de DDT del tram baix de la conca del riu Ebre i determina l'origen d'aquest pesticida, actualment prohibit a l'Estat espanyol.
Dispersió atmosfèrica de contaminants emesos per la planta de Flix (Capítol 2)
S'ha avaluat la dispersió atmosfèrica de COPs mitjançant l'anàlisi d'aquests contaminants en vegetació. S'ha observat que l'activitat industrial que es desenvolupa a Flix actua com a font de contaminació atmosfèrica de COPs. S'ha obtingut un model de distribució per a cada contaminant que ha permès determinar un radi d'influència per a cadascun d'ells. La dispersió de cada contaminant va estretament lligada a les seves propietats físico-químiques.
Impacte de la planta de Flix en l'activitat agrícola del tram baix de la conca del riu Ebre (Capítol 3)
S'ha estudiat el contingut de COPs en 85 finques agrícoles regades amb aigua del riu Ebre des de Flix fins a la desembocadura i s'ha avaluat la transferència de COPs d'aquests sòls a la part comestible dels productes agrícoles que s'hi cultiven. S'han observat nivells de COPs en els sòls agrícoles molt variables però en general les concentracions són baixes. Els sòls amb nivells més alts són aquells que estan situats a prop del llit de riu o bé aquells que es reguen amb quantitats molt elevades d'aigua. La presència de COPs a la part comestible dels productes agrícoles no està directament lligada a la presència de COPs en el sòl a on s'han cultivat. Els nivells de COPs dels productes agrícoles provenen de la incorporació directa de la part aèria de la planta.
Mobilització dels contaminants de l'embassament de Flix aigües avall del riu Ebre (Capítol 4)
S'han analitzat mostres de sediments fluvials del mateix embassament de Flix i d'aigües avall fins al Delta de l'Ebre. S'han observat concentracions molt altes de tots els COPs estudiats excepte els HCHs als sediments de l'entorn de Flix i en cap cas s'observa una disminució de les concentracions respecte les campanyes anteriors. Existeix mobilització i transport dels sediments contaminats de Flix aigües avall d'aquest punt i s'han mantingut constants durant aquest període de temps.
Origen dels residus de DDT de la conca del riu Ebre (Capítol 5)
El DDT és un producte sintètic amb propietats insecticides. El seu ús i producció està restringit des de la dècada dels 70, encara que la prohibició total a l'Estat espanyol no va tenir lloc fins l'any 1994. Tanmateix, actualment encara es detecten quantitats importants de DDT i els seus productes de degradació, DDE i DDD, en sòls, aire, aigua, etc. S'han analitzat els nivells dels isòmers de DDT en mostres de sòls i sediments del tram baix de la conca del riu Ebre per tal de fer una caracterització d'aquests residus. A més s'ha determinat la composició enantiomèrica de l' o,p'-DDT d'aquests sòls per conèixer el seu estat de degradació. S'han identificat almenys dues fonts de contaminació per DDTs relacionades amb l'activitat industrial de Flix i Montsó. A més a més s'han identificat àrees amb aportacions recents de DDT, algunes d'elles relacionades amb l'ús de l'acaricida dicofol.
Persistent Organic Pollutants (POPs) are compounds which have shown to be toxic, persistent, bioaccumulable in animals and humans and with capacity of worldwide atmospheric transport, reaching remote areas where they have never been produced or used. In some specific areas such as the Ebre river basin, contamination by POPs is very high, mainly due to the industrial activity from two chlorine-alkali plants situated in Flix (Tarragona Province, Catalonia) and Monzón (Huesca Province, Aragón).
The present PhD thesis is devoted to assess the impact that this chlorine-alkali plants has had in the lower course of the Ebre river basin. Firstly it evaluates the atmospheric emissions to the environment from the chlorine-alkali factory in Flix. Secondly it studies the mobilization downstream of the polluted sediments placed in Flix water reservoir and the impact of these industrial discharges in the agricultural soils irrigated with water collected downstream. It must be remembered that agriculture encompasses one of the main uses of river water in the Ebre river basin. Finally, the thesis is addressed to characterize the DDT residues in sediments and soils of the lower course of the Ebre river basin and to determine the origin of this pesticide that is currently banned in Spain.
