  • Descrição: Today, society is in a state of frequent change, and this is not different in the disaster risk management field. Responses to social disasters, which were previously treated isolated, are increasingly demanding planning and decision in face of great complexity. In the case of flood events, climate projections combined with urbanization trends show an increase in their intensity. Social aspects, such as the social memory of past events, can play an important role in reducing flood damage through the voluntary displacement of people outside risk areas or the resilience improvement. Such factors demonstrate that the risk analysis must be carried out dynamically, considering that the human-water system co-evolves, to reduce flood risk. The first hypothesis in this study is explored in the second chapter and is that the flood risk can be reduced by keeping the memory of past events alive for longer periods in flood-prone areas. The second hypothesis, explored in the third chapter, is that climate change scenarios and social aspects can be incorporated in long-term risk analysis, improving the risk reduction measures planning. Thus, this study conceptually developed a Socio-Hydrological Observatory for Water Security (SHOWS) that aggregates climatic, social, and hydrological information for flood risk analysis. To this end, a socio-hydrological model was applied using historical data and climate projections for the years between 1940 and 2099 to estimate flood risk in a Brazilian catchment. These results served as a basis for identifying strategies to reduce risk through social and environmental measures and for the elaboration of the observatory model.
