The importance of hydrological simulations in the climate change context : Tiete river basin study case

In the follow decades the world will face a huge challenge with the climate changes. Many are the studies that show changes in the variability of precipitation and temperature in the XX century. In this context, some countries present great vulnerability and more intense studies are necessary to better understand and predict the future events, as as the occurrence of drougths, floods and water availability. Brazil is one of these countries because of its agriculture economy, the depedency of hydropower plants in its energetic system and the presence of intense population agglomerates next to coastal areas and in regions with vulnerability to drougths and floods. There is still some challenges in predict the impacts in this territory and the use of hydrological models with a better resolution are fundamental. In this context, a model developed in Politecnico di Milano, the FEST-WB was used to made preliminar simulations in Tiete River Basin. It was possible to reach some conclusions and understand better the main challenges of making such studies.
