The aim of this study was to test whether the richness observed and the biomass per trophic group of fish assemblages vary depending on the order (1st and 2nd) of the streams located in three different basins of the Upper Paraná River Basin, Central Brazil. Samples were collected between April and September, 2009, in 27 streams of the Meia Ponte, Piracanjuba and Santa Maria River basins. A total of 4,879 specimens were collected distributed in 59 species and 19 families. The statistical analyses carried out indicate that the observed richness and biomass of omnivore fish were influenced by the interaction of two factors: stream order and basin. The 2nd order streams located in the Santa Maria basin presented significant differences in the observed richness and omnivore biomass when compared to i) 1st order streams in the same basin (only richness) or in the Piracanjuba and Meia Ponte basin; ii) 2nd order streams in the Piracanjuba (only omnivore biomass) and Meia Ponte Rivers basins. Results are discussed considering the influence of geomorphic processes on fish assemblages and food availability.

AIM: The main objective of the study was to evaluate the limnological characteristics of rivers flowing through urban and rural areas in the upper Uruguay River basin in western Santa Catarina (SC), Brazil. METHODS: Sampling sites in the tributaries were selected along the longitudinal gradient and the different use of the soil in adjacent areas. Samples were collected bimonthly from March 2005 to August 2006. The following were analysed: depth, pH, electrical conductivity, dissolved oxygen concentration (DO), water temperature, chemical oxygen demand (COD), total alkalinity, ammonia, nitrite, nitrate and phosphorus were analysed. RESULTS: In most of the rivers analysed, we found a continuum from the spring to the river mouth that was characterised by a gradual increase in electrical conductivity, COD, phosphorus, alkalinity, nitrite and nitrate. However, an alteration from this pattern was found in rivers passing through urban areas. This deviation was due to high organic matter input poured into the rivers from these areas. CONCLUSIONS: Degraded riparian forest was observed along most of the bodies of water, which facilitates the entry of pollutants. Although the studied area suffers from intense farming activity (agriculture and livestock) and has the highest concentration of swine livestock in the country, the rivers that were most altered from their natural state were those that were influenced by sewage and industrial effluents from urban development.

Los caudales ecológicos se definen como el régimen fluvial en un cuerpo de agua que permite mantener el funcionamiento del ecosistema acuático en condiciones naturales. La legislación ambiental en México – Ley de Aguas Nacionales (LAN), Ley General del Equilibrio Ecológico y Protección Ambiental (LGEEPA) –, en concordancia con la legislación de países europeos, establece la necesidad de definir caudales en las corrientes superficiales perennes que permitan, ante los diversos usos que se le da al agua que circula por ellas, la existencia o permanencia de la fauna acuática. En el río Valles, localizado en el estado de San Luis Potosí, México, se ha presentado en diferentes años mortandad de peces en la época de estiaje, ello como consecuencia del incremento en las extracciones de agua para uso doméstico y agroindustrial, así como por las descargas de aguas residuales al río. Debido a lo anterior los usuarios, representados en el Comité de Cuenca del río Valles, han establecido, en dos zonas, un nivel de referencia que ha disminuido la mortandad de peces; sin embargo, aún se tienen efectos nocivos en la fauna acuática. En tal sentido, los objetivos de esta investigación fueron estimar los caudales ecológicos en el río Valles con el método Tennant y analizar la variación espacio-temporal de los mismos. Se fijaron dos puntos (Micos y Santa Rosa) y dos períodos (1960-1975 y 1976-2000) de análisis; los resultados muestran que los caudales medios anuales están disminuyendo, generando un decremento en los caudales ecológicos del 10 %. De acuerdo a los resultados se pueden inferir condiciones ecológicas adversas de marzo a mayo en el tramo Micos-Santa Rosa-El Pujal.

We report macro and meso palaeobotanical records from the Zarzal Formation, in the Cauca River Depression, and the Quindío-Risaralda Basin between the Western and the Central Cordilleras of Colombia. The fossils correspond to leaves and seeds obtained from layers of mudstones, diatomites, and tuffaceous sandstones deposited in the inter-Andean valleys of Cauca and La Vieja rivers, separated by the Serranía Santa Bárbara ridge between the Valle del Cauca and Quindío departments. The sediments of the Pleistocene Zarzal Formation were deposited in a fluvial-lacustrine environment, with volcanic influence originated in the Central Cordillera to the east of the depositional area. The study here presented allowed the identification of thirteen morphotypes of leaf impressions grouped in six Angiosperm families: Poaceae?/Cyperaceae? and Araceae of the Monocots group, Melastomataceae, Fabaceae and Lauraceae belonging to the Eudicots group and one family of Lycopsida: Thelypteridaceae. On the other hand, very well-preserved silicified micro-seeds were grouped in eight morphotypes, belonging to the botanical groups Cyperaceae and Asteraceae. The fossils found allowed us to identify two types of plant associations that exhibit paleofloristic richness. In the Cauca River Basin, an autochthonous to parautocthonous plant association could correspond to a sub-Andean gallery forest, whilst in the La Vieja River Basin a parautocthonous plant association indicates a swamped floodplain. Keywords: paleoflora, leaves, seeds, Cauca River, La Vieja River, lacustrine deposit.

This paper describes the success of an ad hoc citizen group in developing an integrated water resource plan for the Santa Fe River in the high desert of New Mexico. Much of the time the Santa Fe River, which runs through the centre of town, is dry because of impoundments for water supply. Water management responsibilities in the area are divided between eight government agencies. Each agency has its own narrowly perceived agenda for managing that aspect for which it is responsible. It was apparent that a holistic approach to water management was sorely needed. An ad hoc citizen committee was formed without government support (either technical or financial), to attempt to bring some rational planning to the use of existing water resources in the growing community.

Annotation:
The Black-collared Hawk (Busarellus nigricollis) is a buteonine with a wide distribution through neotropical region. It has preference for aquatic habitats, where it feeds on fishes. It has few records for southern Brazil. In Rio Grande do Sul (RS) State, it is rare, and the only documented record is a collected specimen in Santa Cruz do Sul, more than seventy years ago. Here we report new documented records for western and central region of RS. The first one was a juvenile observed in December 2020 at the Wetland of Butuí-mirim. The second one was an immature observed on April 2021 at Butuí River. Both observations were made in São Borja, and reaffirm its occurrence in the Butuí River Basin. The third record was in the central region of RS in June 2022, and its occurrence may be associated to the low Jacuí River. The regional status of the Black-collared Hawk is unclear. It was considered threatened in the past, but now it is regarded as not applicable for evaluation. The Butuí River Basin has many wetlands in the course of its rivers, although some were drained and converted into rice fields. Future actions should be considered regarding the conservation of the wetlands of Butuí River Basin.

Geomorphologic methods document poorly exposed tectonically active structures in the first study to determine quantified ages for Quaternary Age fluvial terraces at Santa Cruz Creek. GPS surveys of three flights of terrace surfaces and a stream gradient profile reveal deformation at the Baseline/Los Alamos fault zone and Little Pine fault. Optically Stimulated Luminescence (OSL) dating was employed to determine ages for the terraces. The formation age of Terrace 1 is 19.3 ka with an incision rate of 1.63 to 1.82 mm/yr, Terrace 2 was dated at 32.9 ka with incision rate of2.02 to 1.82 mm/yr. Based on incision rates an estimated age of 44.0-47.0 ka was calculated for Terrace 3. Offsets in T-2 and T-3 were used to calculate a short term faulting rates of .91 mm/yr and a long term faulting rate of 0.67 to 0. 73 mm/yr for the Baseline/Los Alamos fault.

A two-phase study of the Upper Santa Cruz River Basin consisting of a hydrologic assessment and the application of a computer model to the area is presented. Groundwater occurs in Older and Younger Alluvium units, is held under unconfined conditions, and is of good quality. The Finite-Difference Three-Dimensional Groundwater Flow Model (MODFLOW) is applied to the study area in order to simulate the hydrologic system. A water budget and conceptual model is developed to aid in model input and calibration. A steady-state analysis for the system is performed for 1965 in order to calibrate model parameters and produce initial conditions for the transient analysis. A transient analysis is performed to verify model response over the period 1965-1980 in which stresses to the system are changing. Model-produced trends and water levels are consistent with observed data, indicating the model's utility for predictive analysis of the system.

A utilização massiva dos recursos naturais na atualidade, gera como uma de suas consequências, uma vasta depreciação dos componentes bióticos e abióticos que compõe o planeta Terra. A Bacia Hidrográfica do Rio Santa Maria possui uma diversidade fisiografica e constantemente vem sofrendo alterações ocasionadas pelas atividades antrópicas. Há uma demanda, por parte de educadores, técnicos e gestores da região, de informações ligadas a questão ambiental, de forma espacializada e georreferenciada. O presente trabalho possui como objetivo geral analisar e elaborar uma proposta de zoneamento geoambiental, utilizando métodos de mapeamentos automáticos na definição dos parâmetros naturais que servem como base para o estudo e zoneamento geoambiental. A metodologia está baseada na proposta metodológica para zonemanento Geoambiental desenvolvida por Trentin e Robaina 2005, porém como inovação nesse trabalho, optou-se por utilizar a avaliação do relevo através dos Geomorphons os quais serviram de base para a definição de compartimentos do relevo que cruzados com informações referentes a solo e litologias, originaram um mapa com informações fisiográficas. Através da interpolação do mapa fisiográfico com o mapa de uso e ocupação se obteve o mapa geoambiental. Nos resultados foram apresentadas informações sobre a morfometria da área em estudo, também foram definidas três unidades litológicas, três unidades simplificadas de solo, quatro compartimentos de relevo, quatorze unidades fisiográficas, seis classes de uso e ocupação do solo, ainda sete Sistemas e doze Unidades Geoambientais com isso foi possível definir e discutir sobre as potencialidades e suscetibilidades. A elaboração do zoneamento geoambiental, com base na definição de potencialidades e suscetibilidade, são delimitadas a partir de caracteristicas homogeneas da área de estudo, é uma importante ferramenta para avaliação e compreensão das alterações ambientais. Dessa forma, foi elaborado um diagnóstico, no qual foram apresentadas caracteristicas naturais e antrópicas da Bacia Hidrográfica do Rio Santa Maria.

The Santa Maria River Basin has a physiographic diversity and is constantly undergoing changes caused by anthropic activities. There is an existent demand, by educators, technicians and managers of the region, of information related to different topics in a spatialized and georeferenced. The present work has as general objective to analyze and elaborate a proposal of geoenvironmental zoning, using automatic mapping methods in the definition of the natural parameters that serve as the basis for geoenvironmental study and zoning. The methodology is based on the methodological proposal for Geoenvironmental zonemanento developed by Trentin and Robaina 2005, but as innovation in this work, it was decided to use the evaluation of the relief through the Geomorphons which served as the basis for the definition of relief compartments that crossed with Information on soil and lithologies, originated a map with physiographic information. Through the interpolation of the physiographic map with the map of use and occupation the geoenvironmental map was obtained. The results were presented with information on the morphometry of the study area, three lithologic units were defined, three simplified soil units, four relief compartments, fourteen physiographic units, six use classes and soil occupation, seven systems and twelve units Geoenvironmental with this it was possible to define and discuss about the potentialities and susceptibilities. The elaboration of geoenvironmental zoning, based on the definition of potentialities and susceptibility, are delimited from homogeneous characteristics of the study area, is an important tool for evaluation and understanding of environmental changes. In this way, a diagnosis was elaborated, in which natural and anthropic characteristics of the Santa Maria River Basin were presented.

Resumo: Os Comitês de Gerenciamento de Bacias Hidrograticas têm sido objeto de uma série de estudos de caso, que apresentam as particularidades da formação, representação e atuação destes Comitês sem situá-Ios em um contexto maior. Neste trabalho procura-se mostrar uma visão geral da importância dada aos problemas ambientais a partir das últimas décadas do século XX, e, em especial, a importância assumida pelas questões de manejo, recuperação e conservação dos recursos hídricos no Brasil. São apresentados de modo detalhado o Sistema de Gerenciamento de Recursos Hídricos do Brasil, de 1997, e de Santa Catarina, de 1994, a fim de mostrar o papel dos Comitês de Gerenciamento de Bacias Hidrográficas nestes Sistemas. Tratando de modo mais específico, foram apresentadas as potencialidades e as dificuldades da atuação e o trabalho dos 16 Comitês de Gerenciamento de Bacias Hidrográficas no Estado de Santa Catarina, dentro da metodologia do Sistema de Gerenciamento de Recursos Hídricos que as idealizou. Por fim, são apontadas as contribuições que a Geografia pode dar ao processo de gestão de recursos hídricos no Brasil.

Stakeholder participation is a foundation of good water governance. Good groundwater governance typically involves the co-production of knowledge about the groundwater system. Models provide a vehicle for producing this knowledge, as well as a boundary object around which scientists and stakeholders can convene the co-production process. Through co-production, stakeholders and scientific experts can engage in exchanges that create system knowledge not otherwise achievable. The process involves one-way transfer of information, active two-way conversations, and integration of multiple kinds of knowledge into shared understanding. In the Upper Santa Cruz River basin in Arizona, USA, the University of Arizona Water Resources Research Center (WRRC) convened a project aimed at providing scientific underpinnings for groundwater planning and management. This project, entitled Groundwater, Climate, and Stakeholder Engagement, serves as a case study employing the first two stages of knowledge co-production using a hydrological model. Through an iterative process that included two-way communication, stakeholders provided critical input to hydrologic modeling analyses. Acting as a bridging organization, the WRRC facilitated a co-production process, involving location-specific and transferability workshops, which resulted in new knowledge and capacity for applying the model to novel problems.

O avanÃo dos processos de desertificaÃÃo e degradaÃÃo da terra tem se manifestado de forma crescente no semiÃrido brasileiro, muitas vezes ocasionados pela utilizaÃÃo indiscriminada dos recursos naturais, seja para manutenÃÃo do sistema produtivo vigente, ou atà mesmo pela falta de informaÃÃo no manuseio desses recursos. A pesquisa faz uma anÃlise da sub-bacia hidrogrÃfica do Riacho Santa Rocha, localizada no baixo curso do Rio Banabuià cuja Ãrea total à de 675 kmÂ. Como objetivo geral tem-se a anÃlise dos sistemas ambientais da sub-bacia, em carÃter de diagnÃstico, com intuito de estabelecer subsÃdios para futuras intervenÃÃes. A concepÃÃo utilizada para a discussÃo foi pautada nos estudos integrados, com Ãnfase na anÃlise sistÃmica do ambiente. Do ponto de vista metodolÃgico o trabalho foi dividido em seis etapas: anÃlise de material bibliogrÃfico, cartogrÃfico e imagens de satÃlites; produÃÃo de mapas para auxÃlio no campo; trabalhos de campo para a comprovaÃÃo dos dados; correÃÃo e adequaÃÃo do material cartogrÃfico produzido para o contexto da pesquisa; aplicaÃÃo de questionÃrios e dos indicadores geobiofÃsicos de desertificaÃÃo. A partir da metodologia empregada foram delimitados cinco sistemas ambientais: planÃcie ribeirinha e Ãrea de inundaÃÃo sazonal; tabuleiros interiores com coberturas colÃvio-eluviais detrÃticas; sertÃes pediplanados de Morada Nova; sertÃes moderadamente dissecados de Jaguaretama e cristas residuais e inselbergs. Percebeu-se que a utilizaÃÃo dos recursos naturais nÃo à uniforme ao longo da sub-bacia hidrogrÃfica, obedecendo Ãs potencialidades e limitaÃÃes de cada sistema ambiental. Os sistemas ambientais caracterizados pelos sertÃes ainda sÃo as Ãreas mais vulnerÃveis à desertificaÃÃo do ponto de vista geoambiental, ainda mais as Ãreas historicamente utilizadas para a subsistÃncia local. Mesmo com cenÃrios desanimadores, ainda se constatou uma melhora das condiÃÃes de vÃrias comunidades, fruto da melhor acessibilidade aos recursos e dinamicidade econÃmica. Apesar dessa variÃvel positiva, essas Ãreas ainda sÃo esquecidas e desprovidas de assistÃncia por parte do poder pÃblico local.
The advance of desertification and land degradation has manifested increasingly in the Brazilian semiarid region, often caused by the indiscriminate use of natural resources, is to maintain the current production system, or even the lack of information in the management of this resource. The research examined the sub-basin of the creek Santa Rock, located in the lower course of the river and Banabuià with a total area of 675 km Â. As a general objective has been the analysis of the sub-basin environmental systems in diagnostic character, in order to establish a basis for future interventions. The design used for the discussion was based on integrated studies, with emphasis on the systemic analysis of the environment. From the methodological point of view the work was divided into six stages: analysis of publications, cartographic and satellite images; production of maps to help in the field; fieldwork for verification of data; correctness and adequacy of cartographic material produced for the research context and questionnaires. From the methodology used five environmental systems were defined: riverine plain area and seasonal flooding; interior trays with colluvial - eluvial covers detrital; pediplanados hinterlands of New Street; hinterlands moderately dissected Jaguaretama and residual inselbergs and ridges. It was noticed that the use of natural resources is not uniform throughout the sub-basin, according to the potentialities of each environmental system. Environmental systems characterized by hinterland are still the most vulnerable areas from the point of view geoenvironmental, further areas traditionally used for local livelihoods. Even with disappointing scenarios was also found an improvement of the conditions of various communities as a result of better access to resources and economic dynamism. Despite this positive variable, these areas are still neglected and deprived of support by the local government.

For over a century of mineral coal exploration in the Santa Catarina Carboniferous Basin, many environmental damages caused by this activity are accounted, such as water pollution, vegetation destruction and disabling of large areas. In coal mining, the pyrite (iron sulfide - FeS2) contributes effectively to the acid drainage formation and metal solubilization in aquatic envoronment. So that, the selection of proper analytical techniques is needed for the quantification of a specific metal, and it is important to have an idea of the concentration in a given sample (expected concentration) using certified reference samples. Therefore, this study was conducted in two chapters: Chapter I presents and discusses the digestion analytical methods for Fe and Pb and reading for Zn in sediment and the procedures used for its validation; and Chapter II presents the characterization and results discussion regarding the presence of metal caused by coal mining activities in the matters of water and sediment of the Palmeiras River, located in the Tubarão Basin. Lower temperature variations and higher Fe and Pb recovery rates was observed in the digestion performed at a shorter time. The use of least squares background correction (LSBC) for Zn readings allowed to obtain values that are more accurate. In the water, there were increase in Ca, Mg, Fe, Al, Mn, Zn, and Pb concentrations, due to the coal mining, while in the sediment, there were a reduction of Al, Mn, Zn, Cu and Pb concentrations, enabled by solubilization due to the low pH of the water
Ao longo de mais de um século de exploração de carvão mineral na Bacia Carbonífera Catarinense, são muitos os danos ambientais provocados por essa atividade, como a poluição dos recursos hídricos, a destruição da vegetação e a inutilização de áreas extensas. Na mineração de carvão, a pirita (sulfeto de ferro - FeS2) contribui de forma efetiva para a formação de drenagens ácidas e a solubilização de metais no meio aquático. Neste contexto, a seleção de técnicas analíticas apropriadas faz-se necessária, para a quantificação de um determinado metal, e também é importante ter uma noção da concentração em determinada amostra (concentração esperada), com a utilização de amostras de referência certificadas. Portanto, o estudo foi desenvolvido em dois capítulos: no Capítulo I são apresentados e discutidos os métodos analíticos de digestão para Fe e Pb e de leitura para Zn em sedimento e os procedimentos utilizados para sua avaliação; e no Capítulo II foi efetuada a caracterização e a discussão dos resultados referentes à presença de metais resultante da atividade mineradora de carvão, nos compartimentos água e sedimento, do Rio Palmeiras, localizado na Bacia do Tubarão. Observouse menores variações de temperatura e maiores taxas de recuperação de Fe e Pb na digestão realizada em menor tempo. O uso da correção de fundo por mínimos quadrados (LSBC) nas leituras do Zn possibilitou a obtenção de valores mais acurados. Na água, ocorreu aumento das concentrações de Ca, Mg, Fe, Al, Mn, Zn, e Pb em função da mineração de carvão, enquanto que no sedimento, ocorreu a diminuição das concentrações de Al, Mn, Zn, Cu e Pb, propiciada pela solubilização devida ao baixo pH da água

<em>Abstract.</em>—We assessed the structure of periphyton, benthic macroinvertebrate, and fish assemblages and their associations with environmental variables at 17 sites on streams of the highly urbanized Santa Ana River basin in Southern California. All assemblages exhibited strong differences between highly urbanized sites in the valley and the least-impacted sites at the transition between the valley and undeveloped mountains. Results within the urbanized area differed among taxa. Periphyton assemblages were dominated by diatoms (>75% of total taxa). Periphyton assemblages within the urbanized area were not associated with any of the measured environmental variables, suggesting that structure of urban periphyton assemblages might be highly dependent on colonization dynamics. The number of Ephemeroptera, Trichoptera, and Plecoptera (EPT) taxa included in macroinvertebrate assemblages ranged from 0 to 6 at urbanized sites. Benthic macroinvertebrate assemblages had significant correlations with several environmental variables within the urban area, suggesting that stream size and permanence were important determinants of distribution among the species able to survive conditions in urban streams. Only 4 of 16 fish species collected were native to the drainage. Fish assemblages of urbanized sites included two native species, arroyo chub <em>Gila orcuttii </em>and Santa Ana sucker <em>Catostomus santaanae, </em>at sites that were intermediate in coefficient of variation of bank-full width, depth, bed substrate, and water temperature. Alien species dominated urbanized sites with lesser or greater values for these variables. These results suggest that urban streams can be structured to enhance populations of native fishes. Continued study of urban streams in the Santa Ana River basin and elsewhere will contribute to the basic understanding of ecological principles and help preserve the maximum ecological value of streams in highly urbanized areas.

Flowing from the Picos de Europa mountain range into the Bay of Biscay (in a SW–NE direction), the River Sella is the main dividing axis of the highly mountainous territory of Asturias, northern Spain, with peaks up to 2,500 metres. The first known human traces in the Sella river basin date back to the Middle Palaeolithic and include remains of thirteen Neanderthal individuals found in the cave of El Sidrón. Archaeological remains dating to the Upper Palaeolithic and the Epipalaeolithic are frequent throughout the region. The adoption of the Neolithic way of life in Asturias was modest. The polished axes found in large numbers and mostly manufactured with rocks imported from other regions, are one of the main sources of evidence to study the Asturian Neolithic. The most noticeable archaeological evidence for this period is, however, the megalithic phenomenon, the earliest monuments dating to the beginning of the fourth millennium BC. Unlike the usual concentrations of barrows and dolmens in other areas of northern Iberia, these constructions are often found on high ground, strategically overlooking the main stretches of well-travelled pathways. The most prominent Asturian megalith, Santa Cruz (Cangas de Onís), however, differs from the pattern outlined above, as it was placed on a fluvial terrace, on a location often flooded by the Sella and Güeña rivers, which meet here (Blas Cortina 1997a; 1997b). The low altitude and the fair conditions of the optimal Holocene would have provided the basis for a densely forested environment throughout the fifth and fourth millennia bc. Historically, the most populated town of this region has been Cangas de Onís, located in the confluence of the Sella and Güeña rivers, where the best agricultural land is also found. These apt conditions also extend to the adjoining valley of Güeña, home to the sites of Covadonga and Abamia, which bear witness to the interweaving of prehistoric memory and Medieval affairs that will be discussed in this chapter.

The Southern California Coast Range domain is a mountainous region with subparallel ridges aligned north–south, or more precisely north, northwest–south, southeast, and with intervening valleys that are controlled by strike-slip faulting. It extends about 400 km from the Golden Gate at the entrance to San Francisco Bay south to the Transverse Ranges that have east–west trending ridges. The domain corresponds to a physiographic region about 400 km long and 100 km wide that is bound by the Pacific Ocean on the west, the Great Valley of California on the east, on the north by the drainage outlet of the Sacramento and San Joaquin Rivers through the Carquinas Straight and San Pablo Bay, and on the south by the Transverse Ranges. Ridges in the Southern California Coast Ranges generally have nearly level crests (Page et al. 1997), but they range considerably in height up to about 1500 m on some of the higher peaks. No streams from the Great Valley cross the Southern California Coast Ranges to the Ocean; the Great Valley drains through the Carquinez Straight and Golden Gate at the north end of these ranges. The larger streams in the Southern California Coast Ranges drain from the Santa Clara Valley, Salinas Valley, and Cuyama Valley to the San Francisco, Monterey, and San Luis Obispo bays. Only relatively small streams drain to the Great Valley, but some of them have large alluvial fans in the valley. There are many Tertiary-faultbound valleys and basins among the mountain ranges. Some of the more prominent basins are the Santa Maria basin, Carrizo Plains, Paso Robles basin, and Watsonville basin. Serpentine is scattered in relatively small bodies throughout the domain and is concentrated along some of the major faults and in the New Idria area (locality 3-12). Climates range from cool and foggy along the coast to warm inland, with hot and dry summers inland from the fog belt.

<em>Abstract.</em>—The Santa Ana River basin is the largest stream system in Southern California and includes a densely populated coastal area. Extensive urbanization has altered the geomorphology and hydrology of the streams, adversely affecting aquatic communities. We studied macroinvertebrate and periphyton assemblages in relation to two categorical features of the highly engineered hydrologic system—water source and channel type. Four water sources were identified—natural, urban-impacted groundwater, urban runoff, and treated wastewater. Three channel types were identified—natural, channelized with natural bottom, and concrete-lined. Nineteen sites, covering the range of these two categorical features, were sampled in summer 2000. To minimize the effects of different substrate types among sites, artificial substrates were used for assessing macroinvertebrate and periphyton assemblages. Physical and chemical variables and metrics calculated from macroinvertebrate and periphyton assemblage data were compared among water sources and channel types using analysis of variance and multiple comparison tests. Macroinvertebrate metrics exhibiting significant (<EM>P </EM>< 0.05) differences between water sources included taxa and Ephemeroptera-Plecoptera-Trichoptera richness, relative richness and abundance of nonchironomid dipterans, orthoclads, oligochaetes, and some functional-feeding groups such as parasites and shredders. Periphyton metrics showing significant differences between water sources included blue-green algae biovolume and relative abundance of nitrogen heterotrophic, eutrophic, motile, and pollution-sensitive diatoms. The relative abundance of trichopterans, tanytarsini chironomids, noninsects, and filter feeders, as well as the relative richness and abundance of diatoms, were significantly different between channel types. Most physical variables were related to channel type, whereas chemical variables and some physical variables (e.g., discharge, velocity, and channel width) were related to water source. These associations were reflected in correlations between metrics, chemical variables, and physical variables. Significant improvements in the aquatic ecosystem of the Santa Ana River basin are possible with management actions such as conversion of concrete-lined channels to channelized streams with natural bottoms that can still maintain flood control to protect life and property.

Atribui-se aos empreendimentos hidrelétricos o conceito de energia limpa, mas na prática não é isso que se vê, visto que, a instalação de seus lagos e a interação com as características originais do local de instalação geram impactos ambientais, causando problemas físico-territoriais e de ordem socioeconômica. Neste estudo busca-se compreender a questão das transformações recentes da rede de cidades em regiões de bacias hidrográficas brasileiras, de grande valor energético e, portanto, suscetíveis a implantação de hidrelétricas, com foco no desenvolvimento de seus balneários e seu potencial turístico. Neste contexto são analisadas as transformações recentes da cidade de Palmitos e do Balneário de Ilha Redonda, discutindo os limites e potencialidades de sua relação com a gestão local através dos mecanismos propostos pelo Consórcio Foz do Chapecó Energia, responsável pela implantação da usina hidrelétrica Foz do Chapecó, na bacia do rio Uruguai, em Santa Catarina. The concept of clean energy is attributed to the hydroelectric enterprises, but in practice that is not found, since the installation of its lakes and the interaction with the original features of the installation place generate ambient impacts, causing physical, territorial, social and economic problems. This study aims to understand the recent transformations in cities in Brazilian hydrographical regions basins that have great energy value and, therefore are susceptible to hydroelectric plants implantation, focusing on the development of its healthresorts and its tourist potential. In this context the recent transformations in the city of Palmitos and in the Ilha Redonda Health-resort are analyzed, discussing the limits and potentialities of its relation with the local management through mechanisms proposed by the Foz do Chapecó Energy Consortium, responsible for the implantation of the hydroelectric plant Foz do Chapecó in the Uruguay river basin, in the State of Santa Catarina.

The state of Santa Catarina, Brazil, has its largest urbanization on the Atlantic slope, consisting of independent river basins that flow to the coast. The development of relatively close cities and complementary economic activities consolidated a multipolarized urban network. In this context, the Itajaí-Florianópolis axis has witnessed an accelerated demographic growth, due to the various economic activities then present (industry, commerce, services, logistics, etc.) which are added to the tourist activities of the last decades. Based on these questions, the article carried out a spatial analysis of this area, from a historical perspective of urban growth in the coastal territory of Santa Catarina. It sought to understand how the pre-existing urban fabric is articulated with recent urban structures, originated from a model of tourism urbanization. The analyzes showed that the Itajaí-Florianópolis axis presents a movement towards metropolization along the main highway that connects the Santa Catarina urban network, the BR-101. Keywords: metropolization, tourism urbanization, coastal territory, Itajaí-Florianópolis axis. O estado de Santa Catarina, Brasil, apresenta a sua maior urbanização na vertente Atlântica, constituída por bacias hidrográficas independentes que vertem para o litoral. O desenvolvimento de cidades relativamente próximas e de atividades econômicas complementares consolidou uma rede urbana multipolarizada. Neste contexto, o eixo Itajaí-Florianópolis tem presenciado um acelerado crescimento demográfico, decorrente das diversas atividades econômicas então presentes (indústria, comércio, serviços, logística, etc.) que se somam às atividades turísticas das últimas décadas. Tomando como base essas questões, o artigo realizou uma análise espacial desta área, sob uma perspectiva histórica do crescimento urbano no território costeiro catarinense. Buscou-se compreender de que modo o tecido urbano preexistente se articula com as estruturas urbanas recentes, originadas a partir de um modelo de urbanização turística. As análises indicaram que o eixo Itajaí-Florianópolis apresenta um movimento em direção à metropolização ao longo da principal rodovia que conecta a rede urbana catarinense, a BR-101. Palavras chaves: metropolização, urbanização turística, território costeiro, eixo Itajaí-Florianópolis.

O município de Florianópolis tem apresentado um elevado crescimento demográfico desde 1970. Nos últimos 45 anos, sua população passou de cerca de 150.000 para 470.000 habitantes. A Bacia do Itacorubi, onde se localizam os bairros do Itacorubi, do Santa Mônica, do Córrego Grande, do Pantanal e da Trindade também acompanhou este crescimento, e concentra atualmente cerca de 55.000 moradores. Nesta região existem 28espaços públicos de lazer, incluindo parques, praças e áreas verdes de lazer, e excluindo os canteiros do sistema viário. O objetivo desta pesquisa foi constituir um banco de dados sobre estes espaços utilizando o sistema de informações geográficas (SIG), incluindo variáveis como forma, funções, área, limites, dentre outras. O método está dividido em três partes: estabelecimento das variáveis de investigação, levantamento de dados in loco, a partir da técnica da observação sistemática e tratamento de dados e armazenados em SIG. Como resultado tem-se o banco de dados e o detalhamento dos procedimentos em uma das praças analisadas (Praça Jardim Albatroz). Numa pesquisa futura, pretende-se identificar quais as correlações entre as diversas variáveis mais importantes, como base para a elaboração de um conjunto de diretrizes projetuais. The city of Florianopolis has presented a high demographic growth since 1970. Over the past 45 years, its population has increased from around 150,000 to 470,000 inhabitants. The Itacorubi River Basin, where the districts of Itacorubi, Santa Mônica, Córrego Grande, Pantanal, and Trindade are located, have also followed this tendency, concentrating currently around 55,000 residents. In this region, there are 28 recreational public spaces, including parks, squares, and green areas, but notflowerbeds and lawns. The objective of this research is to create a database on these areas using a geographic information system (GIS) software, including variables such as form, functions, equipments, area,date of creation, among others.The method is divided into three parts: establishment of research variables, on-site data collection, from the systematic observation technique and data processing and storage in GIS. As a result, this paper presents the database and the details of procedures of the analyzed venue (JardimAlbatroz Square). In a following research, it is expected to identify the most important correlations amongthe variables, as a basis for a set of projective guidelines.
