Abstract: |
Grand Yoff, like many localities of niayes area, in Senegal, has experienced devastating floods in 2005, 2009 and 2012. The Senegalese authorities have long opted for the emergency solution what is to set up pumps to relieve populations rainwater invading. But since October 2012, the State of Senegal has established a Ministry of the Restructuring and Spatial flood zones (MRAZI) to ensure the well-being of people living in these areas. The state has also pledged to take measures to reduce the risk of flooding by raising regulatory, and to get financial means in order to achieve structuring networks that could bring lasting solutions to the fight against floods. The EPA SWMM software used for the simulations shows that the existing system was outdated and some structuring works made recently are at risk of overflowing with a decennial rain Kiefer type. |
