13. Dinâmica não-linear em sistemas hidrológicos.
Recentemente, pesquisas em sistemas complexos têm conduzido a novas abordagens e aplicações da modelagem dinâmica não-linear. As recentes alterações no enfoque de estudo de problemas hidrológicos como administração de recursos hídricos, transporte de poluições, infiltração de água no solo, etc., necessitam, principalmente, de uma modelagem pr

14. 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

15. Application of the hydrologic model SWMM in the evaluation of different levels of catchment discretization for rainfall-runoff simulation / Aplicação do modelo hidrológico SWMM na avaliação de diferentes níveis de detalhamento da bacia hidrográfica submetida ao processo de transformação chuva-vazão
For the last years, the distributed hydrological models have been recognized by allowing the incorporation of the spatial variability of catchment characteristics for rainfall-runoff simulation. However, due to this ability, the distributed models tend to be mathematically complex and to require many parameters to be measured or estimated. Although the liter

16. Ecologia e modelagem da distribuição dos sítios de nidificação do jacaré-açu (Melanosuchus niger) em uma área de várzea da Amazônia Central, Brasil
The black caiman, Melanosuchus niger, is primarily an Amazonian species, its largest populations are associated mainly with interior várzea areas, but its nesting ecology related with these hydrologic dynamic environments is still poorly understood. The objectives of this study were related to the generation of information on the nesting ecology of this spe

18. 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.

19. Recuperação de perfis verticais de propriedades óticas inerentes a partir da radiação emergente da água / Reconstruction of vertical profiles of inherent optical properties from upwelling water radiances
The current work proposes a metodology for the reconstruction of inherent optical properties of natural waters, vertical profiles of the absorption and scattering coefficients, from multispectral radiometric data of the radiation emerging from water. The radiative transfer direct model is solved by the LTSN method and bio-optical models are employed to corre

20. Water resources integrated modeling supported by a geographic information system / Modelagem integrada de recursos hídricos com apoio de um sistema de informações geográficas
The relative or complete lack of water has been directing various actions in order to solve this problem. The national water resources politic (Law 9.433/97) with its five instruments for water resources planning and management can be considered the main action. Among these instruments, it is found the information system that has as purpose to collect, store

22. Propostas para gestão integrada dos recursos hídricos na bacia hidrográfica do rio Jardim DF.
The management of the water resources should be based on technical, scientific, political and cultural criteria. The administration of the water should consider a participative approach, involving the administration and the development of the control actions, including the participation of users, planners legislators in all of the levels, being necessary an

23. Abordagens qualitativa e quantitativa de micro-bacias hidrográficas e áreas alagáveis de um compartimento do Médio Mogi-Superior/SP / Qualitative and quantitative approaches to the hydrographic microbasins and floodable areas of a compartment of the Mid-Upper Mogi Guaçu river, SP, Brazil
The search for tools that contribute to enhance the interpretation of information about the diverse uses of soil and their consequences on aquatic bodies is an important task, since the qualities of soil and water have always affected human civilization. The goal of the present work was to quantify, by a first approximation and based on existing data, the er

24. Forecasting models for flood in real time at Nova Era county - MG / Modelos de previsão de enchentes em tempo real para o município de Nova Era MG
A bacia do rio Doce é frequentemente atingida por inundações, causando prejuízos econômicos, perdas humanas e materiais. Em decorrência desta problemática, a CPRM (Companhia de Pesquisa de Recursos Minerais) de Belo Horizonte criou, em 1997, o Sistema de Alerta Contra Enchentes da Bacia do Rio Doce, no intuito de minimizar os impactos oriundos das inu
