2. Flow distribution and trends in the Das Velhas River Basin
Resumo Na gestão dos recursos hídricos se deve buscar a harmonização entre as demandas dos usos múltiplos da água e a disponibilidade hídrica, entendendo-se esta como o quantitativo a ser utilizado de forma ambientalmente sustentável. Distribuições de probabilidade de vazões são ferramentas essenciais para avaliar a disponibilidade hídrica. Os o

5. FUZZY INFERENCE SYSTEMS FOR MULTI-STEP AHEAD DAILY INFLOW FORECASTING
ABSTRACT This paper presents the evaluation of a daily inflow forecasting model using a tool that facilitates the analysis of mathematical models for hydroelectric plants. The model is based on a Fuzzy Inference System. An offline version of the Expectation Maximization algorithm is employed to adjust the model parameters. The tool integrates different inflo

6. 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

7. Impacto das Áreas de Preservação Permanente sobre a erosão hídrica na bacia hidrográfica do Rio da Prata, Castelo-ES / Impact of Permanent Preservation Areas on water erosion in the watershed of River Silver, Castelo-ES
A watershed is the primary unit of water resource management, because their behavior affects the hydrological occurrence and magnitude of water erosion. Hydrologic simulation models, which allow to estimate the hydrology and water erosion, consisting of important management tool to minimize environmental degradation in these units. The Permanent Preservation

8. Análise espacial das características hidrodinâmicas e do uso e ocupação do solo da bacia experimental do Riacho Guaraíra mediante uso de geotecnologias / Spatial analysis of hydrodynamic features and land use and occupation of the Guaraira River experimental basin through geotechnology use.
The sedimentation and erosion problems at the hydrographic basin are seen currently as one of the main problems of modern society and consequently of the urban areas and large Brazilian metropolitan regions. The issue of management and water availability in the hydrographic basin must be treated as an Urban Engineering issue, once that it is in charge of the

9. Avaliação da susceptibilidade erosiva da bacia do rio Carinhanha (MG/BA) por meio da EUPS : equação universal de perda de solos
Mathematical models are suitable for a quick and economical assessment of erosion susceptibility. The Universal Soil Loss Equation (USLE), one of the most well-known and used models, predicts erosion susceptibility based on rainfall erosivity (R-factor), slope length (L-factor), slope-steepness (S-factor), cover and management (C-factor), and support practic

10. CritÃrios para AplicaÃÃo do Programa Produtor de Ãgua - Estudo de Caso no Alto Rio Grande / Criteria for application of the Water Producing Program â Case studies in the Alto Rio Grande, MG.
The creation of mechanisms to compensate, financially, the agricultural producers by preservation actions is very recent in Brazil, and began through the Water National Agency proposal â through the Water Producer Program. The proposed model as well as other models that are recently being applied, aims at offer to the agricultural producers a defined value

12. Técnica de gerenciamento da qualidade hídrica superficial baseada na otimização multiobjetivo / A technic of surface water quality management based on the multiobjective optimization
Problems of water quality management involve many aspirations of the users engaged, those that use water for wastewater dilution or for their consumption. Therefore, it is uncommon that decision-making mathematical models used are expressed in terms of a single objective, like the maximization of economic efficiency. Using a particular water system, one shou
