Abstract

The current and persistent flood scenarios and their consequences show the complexity and size of the problem. Despite the technical developments in metropolitan environments, the persistence of floods points out to two types of limitations: in flood forecasting models and policies of control, combating and mitigation. Considering that the discussion must involve, necessarily, the understanding and analysis of the natural attributes of watersheds and the sort of occupations in metropolitan areas, this project intents to develop an integration effort between theses both spatial spheres, through the application of anthropogenic geomorphology combined with the hydrological model Ven Te Chow - SCS. Our objective is to analyze the variability of responses from Ven Te Chow - SCS according to the introduction of morphological (original and anthropogenic) obtained by cartography of geomorfological evolutions. For realizantion of this goal, we propose, firstly, the approach of anthropogenic geomorphology, based on historical cartography, for the reconstitution of the original morphologies and new forms produced by the urban occupation, generating disturbance mappings with varying degrees of susceptibility of floods. And secondly, the application of the hydrologic model Ven Te Chow in several different scenarios in the same basin reconstructed in the previous phase, those determining the increase of runoff and peak flow in the various sectors of the hydrographic basin. Thus, we hope to contribute to the urban geomorphological and hydrological knowledge, especially in their applied areas, and constitute an important link between these two specialties.
