  Ouagadougou is highly exposed to the risk of natural disasters such as flooding as a result of poor urban planning, the physical environment and climate change. The aim of this study is to use remote sensing and Geographic Information System (GIS) tools combined with multi-criteria analysis using Saaty's AHP method to map flood-prone areas in the municipality of Ouagadougou. The methodological approach adopted is a combination of GIS and Saaty's AHP analysis method. Seven decision criteria considered to be risk factors were selected. These are the hydrographic network, altitude, slope, rainfall, soil types, land use and soil moisture index. These various factors were mapped and classified using the open source software QGIS; standardised, prioritised and aggregated in a GIS environment and analysed using the AHP method. The results obtained show the map of different f.. View More»
