Associated Damage Assessment to Flooding in City Blumenau

Floods are among the main types of phenomena associated with socio-economic and environmental damage. Although it occurs public investment and advances in hydro meteorological monitoring and warning systems, the damage is recurring because there are high risks involved. This shows the vulnerability of the city against floods and at the same time, the skills of those affected in live with the risks, while not having conditions Ark them. This study examines the damage related to the historical events of 1983, 1984, 1992 and 2001 in the city of Blumenau (SC), located in southern Brazil. Initially, two approaches have been developed for this evaluation. The first approach was statistically resulting from the application of 387 questionnaires in interviews with residents and merchants of flood areas, and the second approach was economic damage. The results of the two approaches were used in the composition of an evaluation model of tangible damage associated with floods and floods in the city of Blumenau, called MAVEN. The results calculated by the model were considered good, although it presents results with significant discrepancies when applied to extreme hydrometeoro logical events such as the environmental disaster of November 2008, characterized as a result of landslides in large proportion due to the large volume of rainfall without above. One of the results of the model was the need to characterize in detail the input data, since the spatial and temporal peculiarities tend to prevent optimal performance of the MAVIN model. The main conclusion was that the standardization of an evaluation model of damage points (type of MAVIN) can provide greater certainty in determining public policy to minimize future damage and provide good benefits to actuarial calculations for resizing purposes of disaster risks addressed to Insurance Companies.
