25. CALIBRATION AND VALIDATION OF THE SWAT HYDROLOGICAL MODEL FOR THE MUCURI RIVER BASIN
ABSTRACT Hydrological models are becoming more and more widespread, mainly due to their capacity to simulate the impact of environmental changes on water resources. In this way, the aim of this study was to calibrate and validate the SWAT model for the soil and climatic conditions of the Mucuri River Basin, located in the Northeast region of the States of Mi

26. 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

27. Modeling Root Growth, Crop Growth and N Uptake of Winter Wheat Based on SWMS_2D: Model and Validation
ABSTRACT Simulations for root growth, crop growth, and N uptake in agro-hydrological models are of significant concern to researchers. SWMS_2D is one of the most widely used physical hydrologically related models. This model solves equations that govern soil-water movement by the finite element method, and has a public access source code. Incorporating key a

28. INTRODUCING A CAUSAL PAR( p ) MODEL TO EVALUATE THE INFLUENCE OF CLIMATE VARIABLES IN RESERVOIR INFLOWS: A BRAZILIAN CASE
ABSTRACT The Brazilian electricity energy matrix is essentially formed by hydraulic sources which currently account for 70% of the installed capacity. One of the most important characteristics of a generation system with hydro predominance is the strong dependence on the inflow regimes. Nowadays, the Brazilian power sector uses the PAR(p) model to generate s

29. 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

30. Efeitos da espacialização da cobertura florestal e da profundidade dos solos na produção de água de uma bacia hidrográfica / Effects of the spatial distribution of forest cover and the soil depth in water yield of a watershed
Several works related to the theme of water production are being made, having in common the association of forest cover with runoff in watersheds. However, no studies were found where the places where this land cover has optimum effect, because it is dependent on climatic and physiographic conditions of each watershed. The objective of this study is to evalu

31. Dinâmica espaço-temporal das áreas variáveis de afluência da bacia do córrego do Cavalheiro / Spatio-temporal dynamics of variable source areas of Cavalheiro\ s watershed
As áreas variáveis de afluência (AVAs) são dinâmicas, apresentando expansão das áreas saturadas durante os eventos de chuva, geralmente próximas aos cursos d\ água e, no momento que a chuva cessa, estas áreas saturadas se contraem. O escoamento superficial ocorre nessas áreas devido ao excesso de saturação, provocado pelo aumento do volume d\ á

32. Caracterização ambiental e estimativa da produção de cargas difusas da área de drenagem da represa de Itupararanga, SP / Environmental characterization and estimative of diffuse pollution of Itupararanga watershed, SP
The use of satellite images has improved the study of the land use dynamics. Land cover mapping have become fundamental tools in the assessment of landscape changes caused by human action and its influence on regional and urban planning. Computation tools such as Geographic Information Systems and hydrological models have supported these findings. The hydrol

33. Métrica para avaliação da inconsistência hidrológica de terrenos representados por MDE / Metric for evaluate the hydrological inconsistency of terrains represented by DEM
This paper presents a method to evaluate the hydrologic inconsistencies in terrain represented by digital elevation model. This method becomes important because of the widespread use of GIS in the hydrology area and hydrological consistency of digital terrain models have received attention of many researchers. Currently checking the model hydrologic consiste

34. Regionalização de potencial hidrelétrico com escassez de dados : aplicação Moçambique
Hydroelectricity (hydropower) is one branch of water resources engineering, which uses water (river flows) producing electricity. A hydroelectric undertaking, besides providing electricity and its comfort, it also allows the establishment of other productive activities, which provides a good economic and social development of the population (social responsab

A forma como a mancha urbana de São Paulo se adensou e expandiu durante o século XX demonstra que, em vários momentos, interesses econômicos para ocupação indevida das planícies fluviais foram mais fortes do que alternativas técnicas que reservavam espaços nessas áreas para o amortecimento de grandes cheias. O padrão de projetos passou a ser o de

36. Modelagem hidrológica da bacia hidrográfica do rio Bengalas, Nova Friburgo, RJ, utilizando o potencial de geotecnologias na definição de áreas de risco de inundação.
This research focuses on the hydrological study using the potential of geotechnology into runoff modeling of the Bengalas Basin, whose main river, with same name, crosses the city of Nova Friburgo - RJ, in a south-north orientation. This city, one of the most important in "Região Serrana", suffers often with floods and landslides, which, historical data and
