1. Methodology for the construction of an urban flood hazard chart
RESUMO Os eventos de inundação são uma das principais causas de prejuízos econômicos e de perdas de vidas humanas em todo o mundo. Infelizmente, a sua ocorrência tem se tornado cada vez mais frequente e de maior magnitude. Para minimizar os riscos aos quais a população está exposta, torna-se necessário investir em ferramentas que auxiliem no proces

2. Geomorphology-based unit hydrograph models for flood risk management: case study in Brazilian watersheds with contrasting physiographic characteristics
ABSTRACT Heavy rainfall in conjunction with an increase in population and intensification of agricultural activities have resulted in countless problems related to flooding in watersheds. Among the techniques available for direct surface runoff (DSR) modeling and flood risk management are the Unit Hydrograph (UH) and Instantaneous Unit Hydrograph (IUH). This

3. Análise da vulnerabilidade e gestao de risco a desastres por inundacao em municipios do Vale do Açu/RN
As inundações são fenômenos que acontecem frequentemente deflagradas por chuvas rápidas, excessivas ou intensas e de longa duração. Os problemas ocasionados por este fenômeno irão depender, por exemplo, do grau de ocupação das áreas do entorno dos corpos hídricos pelas populações, bem como, da frequência com que as inundações ocorrem. São

4. 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

5. 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

6. Land evaluation of the Maputo province (Mozambique) : a case study of the Changalane and Mazimunhama hydrographic basins / Avaliação de terras da provincia de Maputo (Moçambique) : o caso das bacias hidrograficas de Changalane e Mazimunhama
The study area consists of the sub-basins of the Changalane and Mazimunhama rivers, tributaries of the Tembe river, situated in the Maputo province of Southern Mozambique. The region is recognized by the national and provincial authorities as being under pressure from: agricultural use, deforestation due to uncontrolled exploitation of forests, forest fires

7. As vozes dos que vivem à âmargemâ dos rios urbanos : uma anÃlise do contexto socioambiental da ocupaÃÃo urbana, atravÃs dos discursos da populaÃÃo
The research aims to interpret the political, economic and social context of the residents who live on the banks of rivers in urban poor households, constituting slums in areas subject to flood risk and water related diseases, where poverty affects the occupation of unhealthy and cheap spaces. The research relates environment degradation, loss of quality of

8. Sistema Web-GIS participativo associado a indicadores de gestão descentralizada de risco de inundações / A participatory web-GIS system associated to decentralized flood risk management indicators
This dissertation presents the development and application of an interactive web-GIS in which internet users map flood risk collaboratively by filling up a geotagged form with questions on flood hazard, exposure and vulnerability. Flood risk was also assessed through the use of a set of environmental risk indicators proposed by Mendiondo (2008). The two meth

9. Hidrossolidariedade como princípio de gestão participativa de risco de inundações por associação de bacia / Hydrosolidarity as a principle of participative management of flood risk for basin association
Throughout the XXI century, a culture of solidarity within a river basin is based on legal aspects. In Brazil, it is legitimated by the Federal Constitution of 1988, article 225, caput, "Everybody is entitled to a ecologically-balanced environment, as well of common using by the people and essential to a healthy life quality, being imposed to the Public Powe
