13. IMPACT OF LAND USE CHANGE ON THE WATER BALANCE IN A REPRESENTATIVE WATERSHED IN THE SEMIARID OF THE STATE OF PERNAMBUCO USING THE SWAT MODEL
ABSTRACT The Brazilian semiarid region present high rainfall variability and long dry periods. Thus, the main springs and streams are generally intermittent, and both native vegetation and human activities have a strong influence on hydrological processes and the water yield in the watershed. The aim of this study was to investigate the impacts of reforestat

14. Phosphorus and thermotolerant coliforms’ loads in Brazilian watersheds with limited data: considerations on the integrated analysis of water quality and quantity
RESUMO Análises integradas dos aspectos qualitativos e quantitativos de ambientes aquáticos robustecem a tomada de decisão, que se vincula ao gerenciamento dos recursos hídricos e à promoção dos serviços ecossistêmicos. Contudo, as possíveis vantagens desta integração ainda esbarram em aspectos básicos, como elevadas incertezas devido ao monito

15. Incertezas na simulação hidrológica em pequenas bacias por meio do modelo SWAT
ABSTRACT Hydrological modelling is one of the main tools in water resources management application. However, several factors make it difficult to extrapolate the estimated parameters in basins with large contribution areas to smaller basins. This research analysed the uncertainties of flow simulations in small basins. The methodological process involves the

16. Reproduction, feeding and migration patterns of Prochilodus nigricans (Characiformes: Prochilodontidae) in northeastern Ecuador
ABSTRACT The black prochilodus, Prochilodus nigricans, is an important food fish distributed throughout aquatic habitats of the Ecuadorian Amazon. We sampled gonad weight, body condition, and feeding of this species to address the question of whether changes in these biological parameters are related to hydrological variation and migration patterns. High fre

17. REGIONALIZATION OF MAXIMUM AND MINIMUM FLOW IN THE TELES PIRES BASIN, BRAZIL
ABSTRACT In a watershed there is space and climate variability within its catchment area, causing changes in water qualitative and quantitative characteristics. Thus, the hydrological data collected from a specific basin may be extrapolated to neighboring basins with similar physical characteristics, using techniques of hydrological regionalization. This stu

18. Hydrological Modeling of Tributaries of Cantareira System, Southeast Brazil, with the Swat Model
ABSTRACT The lack of hydrological data in Brazil is the main limitation for structuring hydrological models, which are able to assist water resources management. Therefore, studies are needed to evaluate the performance of models without on-site calibration. Within this context, the aim of this study was to calibrate the SWAT hydrological model for the Caman

19. Assessment of sábalo (Prochilodus lineatus) fisheries in the lower Paraná River basin (Argentina) based on hydrological, biological, and fishery indicators
This study assesses the change in fish exploitation patterns of the sábalo fisheries of the lower Paraná River basin based on hydrological, biological, and fishery indicators. From historical catch records, we recorded a shift from a lightly and moderate exploited status before 2001 to a heavily exploited one, as a result of the development of sábalo expo

20. Ecophysiological responses to the effect of annual management on an endemic viviparous fish in central plateau of Mexico
Studies on the biological aspects of fish typically focus on species that currently have commercial value, causing species that lack such market value to be ignored. This is the case of several freshwater fish, specifically of several members of the Goodeidae family. In the State of Querétaro there are several species of this family characterized for being

21. Análise da influência dos fatores naturais e antrópicos na disponibilidade hídrica no alto curso do Córrego Três Marcos: subsídios para gestão integrada das águas superficial e subterrânea
A presença da água em nosso planeta é determinante para a existência das condições essenciais para origem e a manutenção da vida sobre sua superfície. O presente estudo buscou a análise do uso e ocupação do solo e a sua influência na disponibilidade hídrica no alto curso do córrego Três Marcos. A escolha do alto curso do córrego Três Marcos

22. Análise de medidas de controle de inundações a partir da avaliação de cenários de uso e ocupação do solo na bacia hidrográfica do Córrego do Gregório, São Carlos - SP / Analysis of flood control measures from the assessment of land use scenarios in the Gregorio stream basin, São Carlos - SP
O processo de urbanização vem ocorrendo na maioria das cidades brasileiras de forma desorganizada. Desse modo, um problema recorrente que afeta diversos municípios brasileiros são as inundações. A falta de um planejamento que levasse em consideração a drenagem urbana no início do desenvolvimento das cidades acaba criando condições para que as inun

23. MONITORING THE FLUCTUATION OF THE WATER TABLE IN UNCONFINED AQUIFERS FOR EVALUATION OF THE POTENTIAL RECHARGE IN OUTCROP ZONE OF THE GUARANI AQUIFER SYSTEM IN CACEQUI - RS/BR / MONITORAMENTO DA FLUTUAÇÃO DOS NÍVEIS DE ÁGUA EM AQUÍFEROS FREÁTICOS PARA AVALIAÇÃO DO POTENCIAL DE RECARGA EM ÁREA DE AFLORAMENTO DO SISTEMA AQUÍFERO GUARANI EM CACEQUI - RS
This research aimed to estimate the recharge and groundwater water table fluctuation in areas with withdrawals of groundwater and surface water related to the variation of groundwater levels and rainfall events. The two areas of study was inserted within the Cacequi Municipality, which is located in the Rio Grande do Sul state, southwestern Brazil, in the Gu

24. Species of the Hoplias aff malabaricus complex (Characiformes: Erythrinidae): An investigation of coexistence in a Neotropical floodplain
This study assessed the coexistence of three species of thraira present in the Upper Paraná River floodplain, using population structure as an investigation tool. The species were designated as: Hoplias sp. 1, introduced after the construction of the Itaipu reservoir, and Hoplias sp. 2 and Hoplias sp. 3, native species that have been identified as Hoplias a
