13. LASH model: a hydrological simulation tool in GIS framework / Modelo LASH: uma ferramenta de simulaÃÃo hidrolÃgica com base em SIG / Modelo LASH: uma ferramenta de simulaÃÃo hidrolÃgica com base em SIG / LASH model: a hydrological simulation tool in GIS framework
Modelos conceituais de chuva-vazÃo, aplicados a bacias hidrogrÃficas, sÃo ferramentas Ãteis para auxiliar na gestÃo de recursos hÃdricos, possibilitando estimar variÃveis hidrolÃgicas (por exemplo, vazÃo total e produÃÃo de sedimentos) e predizer impactos hidrolÃgicos decorrentes de alteraÃÃes no uso do solo. PorÃm, a maioria dos modelos tem a

15. 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

16. 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-

17. Segurança de barragens: aspectos regulatórios
In this paper are presented socio-environmental considerations about the dams safety being promoting the linking of the trilogy water, living beings and anthrop actions, as well as the evolution of the legal aspects. A study about the resources is done to establish a policy of efficient action which guarantees few risks of accidents involving dams and as the

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. AvaliaÃÃo ambiental e percepÃÃo dos usuÃrios sobre os efeitos das obras de proteÃÃo de costa nas praias da Casa Caiada (Olinda) e Janga (Paulista)
The coastal zones and special the beaches are dynamical and fragile regions in a continuous change. The high population concentration in these areas results in a pressure increment upon natural resources and increased risk of environmental degradation. The coast of the Sate of Pernambuco, is experiencing coastal erosion that has many times being mitigated wi

20. Avaliação e redimensionamento de redes para o monitoramento fluviométrico utilizando o método sharp e o conceito de entropia
Information of the hydrologic regime characteristics of the watercourses in a hydrologic basin are the starting point for developing water resources management actions taking its multiple uses into account. Setting up of such knowledge is carried out by means of information about the river discharges during certain period through the settlement of monitoring

21. Analysis of grant criteria based on minimum flow and flow according to duration curve for water consumptive uses. / Análise dos critérios de outorga de direito de usos consuntivos dos recursos hídricos baseados em vazões mínimas e em vazões de permanência.
Through these ten years of the Water Resources Brazilian Policy, some difficulties have been presented to the water resources management in so far as the management instruments has becoming solid, mainly to the grant of right for using water resources. A problem of those refers to the low water availability in several water basins, where the total water dema

22. Geotechnologies on hydrographic watershed generation: a instrument for hydric polities / Geotecnologias na geração do divisor de bacias hidrográficas: um instrumento para a Política de Recursos Hídricos
In this work geotechnologies are used to obtaining the watershed in a study case. Taking in account that the Law determines that the hydrographic basin must be considered the elementary study unit, different techniques for obtaining the watershed are tested. In the GIS (Geographic Information System) environment has been used the digital elevation model obta

23. 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

24. AvaliaÃÃo da cobranÃa como mecanismo econÃmico alocativo na gestÃo de bacias hidrogrÃficas: o caso da bacia do Rio Pirapama
The increasing concern about the environment and with the water quantity and quality generated some works in some distinct areas interested in the problem. An existing line of studies is focused on the institution of the charging for the raw water uses, as it foresees the National Water Resources Policy which is established in the Federal Law 9433-97, as for
