Contribution of Geographic Information Systems for the Mapping of Flooding Factors in Yaoundé: The Case Study of Mfoundi Upstream Watershed

摘要

Built on a hilly relief, the city of Yaoundé is exposed to flooding since three decades. They caused human, material and environmental damages. Efficient management of this phenomenon by public authorities should go through a proper control of variables contributing to this hazard. Through various GIS applications based on multi temporal maps and primary data, we developed a detailed mapping of the main natural and human factors responsible for this phenomenon.
