1. ESTRATIGRAFIA GPR E MORFOGÊNESE QUATERNÁRIA NO SEMIÁRIDO BRASILEIRO
Resumo O Parque Nacional da Serra da Capivara desponta como estudo de caso para pesquisas do Quaternário e de geomorfologia no nordeste semiárido brasileiro. Trabalhos anteriores no vale da Serra Branca, uma das principais unidades geomorfológicas do parque, revelam o predomínio de espessos depósitos coluviais, sugerindo flutuações climáticas episód

2. Metals and dissolved organic carbon (DOC) of surface waters in two adjacent watersheds in the eastern Amazon
Resumo A intensificação do uso da terra na região da “Zona Bragantina”, uma área da Amazônia Oriental brasileira, acelerou as mudanças de paisagem da floresta primária para uma mistura de diferentes usos da terra: floresta (vegetação ripária), floresta secundária, pastagem, terra agrícola anual, terra cultivada perene, solo descoberto e veget

3. Environmental services in watersheds with small declivity: fluvial marine plains
Resumo Planícies fluvio-marinhas abrigam ambientes com reduzida declividade, porém com ofertas diferenciadas de atributos ambientais que podem constituir relevantes serviços ecossistêmicos nas suas bacias hidrográficas, que podem ser transformadas em oportunidades para o desenvolvimento de pagamento de serviços ambientais. O estudo espacializou parte d

4. Landscape Ecology in a Watershed of the Ocoy River, Western Parana State, Brazil
ABSTRACT This study evaluated the landscape structure of a watershed located in a region considered strategic for the implementation of the Paraná River Biodiversity Corridor. Based on land-use/land-cover mapping, four different scenarios were generated: 1) real situation, 2) considering the edge effect, 3) without Permanent Preservation Areas (APPs), and

5. Ichthyofauna of streams of the Rio Sapucaí basin, upper Rio Paraná system, Minas Gerais, Brazil
Resumo: A bacia do Rio Sapucaí, no Estado de Minas Gerais, Brasil, é uma das muitas bacias hidrográficas do sistema do alto Rio Paraná. Levantamentos de ictiofauna nessa bacia, em geral, são escassos. Além disso, rios de pequeno porte e córregos da região têm sido alvos de ações antrópicas (e.g., poluição) - o que sugere que mais estudos ictiol

6. Does the landscape surrounding streams affect the occurrence of freshwater crabs? A case study of the genus Aegla (Crustacea: Decapoda: Anomura) in subtropical basins
ABSTRACT Changes in the landscape where watersheds are located may affect the stream biota in different ways. In order to explore this idea, we collected freshwater crabs of the genus Aegla Leach, 1820 in subtropical region of southern Brazil. We also measured a number of landscape features and physico-chemical variables in the collection streams and surroun

7. Performance of a Distributed Hydrological Model Based on Soil and Moisture Zone Maps
ABSTRACT The scarcity of field data to develop soil maps through a pedological survey is one of the main limitations to using distributed hydrological models, especially in small and medium-sized watersheds. The aim of this study was to compare a distributed hydrological model prediction to a soil map based on a pedological survey and a moisture zone map obt

8. Aproveitamento de água de chuva no meio urbano e seu efeito na drenagem pluvial
There is an increasing interest from the society in rainwater harvesting and use in urban areas, due to the benefits that this practice provides, such as: economic, environmental and urban flooding control. This interest may be perceived by the emergence of government regulations and increased availability of specific products in the domestic market for the

9. FLUTUAÇÃO DOS NÍVEIS DE ÁGUA SUBTERRÂNEA EM MICROBACIAS HIDROGRÁFICAS DO RIO VACACAÍ-MIRIM / GROUNDWATER LEVELS FLUCTUATION IN VACACAÍ-MIRIM RIVER SMALL WATERSHEDS
The intention in this work is to study (locally) the fluctuation system of groundwater levels in two small watersheds. We selected Rancho do Amaral and Rincão do Soturno small watersheds for being representative of the first order streams which compose the Vacacaí-Mirim river watershed headwaters. Both are located at the border of Paraná Sedimentary Basin

10. MODELING OF WATER, SEDIMENT AND PHOSPHORUS LOADS IN AN AGRICULTURAL WATERSHED IN SOUTHERN BRAZIL / MODELAGEM DO ESCOAMENTO, DA PRODUÇÃO DE SEDIMENTOS E DA TRANSFERÊNCIA DE FÓSFORO EM BACIA RURAL NO SUL DO BRASIL
Areas under intensive tobacco crop cultivation have been impacting the water balance and increasing soil erosion in Southern Brazil. Application of large amounts of mineral fertilizers, higher than the tobacco requirement, contributes to excessive phosphorus loads in soil and water bodies. The assessment of potential environmental impacts due to changes in l

The studies for small reservoirs in the semiarid northeast are still scarce, mainly in relation to water quality. This research aimed to discover the dynamic processes that occur in small reservoirs, to evaluate the multiple uses, the trophic state and water quality in small reservoirs representing the settlement on May 25. Carried out the systematic monitor
