1. Modified NRCS-CN-TUH methods for distributed rainfall-runoff modeling
RESUMO Pela facilidade de aplicação, os métodos CN e Hidrograma Unitário Triangular (HUT) são muito usados em projetos de obras hidráulicas. Este trabalho adapta tais métodos para incorporar a variabilidade espacial das características físicas da bacia hidrográfica. O tempo de viagem (tv) do escoamento é computado do MDE e os métodos CN e HUT s�

2. 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

3. Simulação hidrológica de rios com grandes planícies de inundação
Besides understanding the current hydrologic behavior of a river and floodplain drainage system, it is important to be able to predict its future conditions in light of possible impacts due to anthropogenic activities and climate variability. Mathematical modeling is the ideal tool for this purpose. For large scale hydrologic systems, if the objective is to

4. Flood insurance model based on hydrological simulation as a flood risk management tool / Modelo de seguro para riscos hidrológicos com base em simulação hidráulico-hidrológica como ferramenta de gestão do risco de inundações
Recent disasters caused by extreme hydrological events, occurred in Brazilian cities, have exposed how fragile the current policies are to manage such situation. Often, a lack of resources is observed even for emergency actions, while structural actions commonly consist of palliative and punctual measures that do not promote real solutions considering the wa

5. ESTIMATIVA DE PARÂMETROS HIDRODINÂMICOS DE AQUÍFEROS EM ÁREAS DE EMBASAMENTO ATRAVÉS DE MÉTODOS INDIRETOS / ESTIMATIVA DE PARÂMETROS HIDRODINÂMICOS DE AQUÍFEROS EM ÁREAS DE EMBASAMENTO ATRAVÉS DE MÉTODOS INDIRETOS
The recession represents the period when the rivers flow is maintained predominately by subterranean water return, so establishing the base flux. In hydrographic basins, the recession coefficient (or of drain) can be determined in an indirect manner by several graph methods using series of hydrologic data. From this coefficient is possible to calculate other

6. Procedimentos para aprimorar a regionalização de vazões: estudo de caso da bacia do Rio Grande / Procedures to improve the hydrologic regionalization: study of Rio Grandes basin
The hydrologic regionalization constitutes an efficient instrument to plan and manage the water resources, and it can be used to obtain the hydrological variables, as the maximum, minimum and medium discharges, in a simple and fast way. This technique can minimize the absence of hydrologic information in sites with low or no data availability. However, some

7. Proposta conceitual para a regionalização de vazões / Conceptual proposal for the hydrologic regionalization
The knowledge water availability through hydrographic net is fundamental to management water resources concession use rights. Normally this knowledge is restrict to the places where exist fluviométrica measurement station. Hydrologic regionalization is a technical tool to supply lack of information where there are few or no data availability. From a socio-

8. Modelagem hidrológica dinâmica distribuída para estimativa do escoamento superficial em uma microbacia urbana
- Floods and inundations are serious problems in Brazilian cities as a result of inappropriate urbanization processes. Impervious surface reduces or makes water infiltration impossible, leading to significant increases in surface runoff. Considering this scenario, this work aims at applying a dynamic distributed hydrological model in order to estimate surfac

9. Dinâmica do uso dos recursos hídricos nas bacias do ribeirão Entre Ribeiros e do rio Preto, afluentes do rio Paracatu / Water resources use dynamics in watersheds of Ribeirão Entre Ribeiros and Rio Preto, tributaries of the Paracatu River
From times past, humanity confronts problems of environmental degradation. The environment, which always performed efficiently its function of filtration, today finds itself excessively overburdened by human activities: it suffers the risk of its resources exhausting, not being able in certain situations to recuperate itself and needing the help of man.

10. Land use change and hydrologic behavior analysis in the Preto river and Entre Ribeiros creek basins / Mudanças no uso do solo e comportamento hidrológico nas bacias do rio Preto e ribeirão Entre Ribeiros
The water resources planning and management have the objective to discuss and propose solutions for the watersheds problems looking for the sustainable water use in the urban and rural areas. The relationships between the land use and water resources have been marked by the failure, with environment significant damages, what has transformed in losses for all

Cabuçu de Cima watershed is located at Cabuçus Nucleus of the Parque Estadual da Cantareira, in the county of Guarulhos, on the northeast of the Metropolitan Region of São Paulo. It has 23,8 km2 surface and contributes for homonymous reservoir of the county water producing system (SAAE Serviço de Abastecimento de Água e Energia do Município de Guarulho

12. Análise das relações climato-hidrológicas e das demandas hídricas no alto curso da bacia hidrográfica do Rio Bagagem/MG
The rational searching for rational use of the hidric resources motivated this thesys whose objetctive was to know the climate-hidrologic processes that happen inside a hidrografic basin by the human interference in the environment. The understanding of those processes propitiated subsidies for the understanding of the space organization of the area, mainly
