Abstract: This study aims to assess the vulnerability to flooding of the population living along the Tile river. A survey sheet for semi - directed and observational interviews with targets and actors is used. Excel software and Flood Vulnerability Index (FVI) formulas allowed us to process our data and arrive at the following results: 209 households were surveyed, 30% of which were considered fair and 70% poor, while 29 % of households recorded physical disabilities.189 people out of 209 (90%) prefer to take refuge with close relatives and neighbors; 4% have shelters both at the military camp and schools, 3% in schools and hospitals and finally 3% in the military camp and hospitals.66% have no means of defense against floods while 34% of households have protective walls.56% believe that the floods come from high rainfall and an anarchic occupation of flood plains; 28% believe that flooding is due to blocked gutters and agricultural activities; 14% to the obstruction of gutters and illegal constructions in flood plains and 2% to the obsolescence of the gutters.
