A high intensity of rainfall experiences flooding in some areas. Flooding can be caused by several aspects, such as inadequate urban drainage, reduce the porous surface due to rapid development and the topography of the area itself.

Therefore, many things that must be considered by the local government in overcoming the problem of this flood, including improvements of the drainage system, reforestation and create the polders. In this research, it is described the area of the prone area in Padang city with spatial analysis tools which are approached in the Geographical Information System. Based on the topography of the Padang city, inundated areas and flood direction will be presented in case of the heavy rain occurs.
