14. 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

15. INTERMITTENT AND CONTINUOS FLOODING IN RICE: WATER USE, AGRONOMIC EFFICIENCY AND IMAZETHAPYR, IMAZAPIC AND FIPRONIL DISSIPATION / IRRIGAÇÃO CONTÍNUA E INTERMITENTE EM ARROZ IRRIGADO: USO DE ÁGUA, EFICIÊNCIA AGRONÔMICA E DISSIPAÇÃO DE IMAZETHAPYR, IMAZAPIC E FIPRONIL
Every anthropogenic activity causes environmental impact in some extent. Rice paddy fields area are pointed out as an activity with high potential of pollution due to the large amount of water used to maintain the flooding and the intensive use of pesticides and nutrients that can be transported to the environment. Though, there are other irrigation manageme

21. 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
