Given its geographical location within a fairly humid area generally characterized by a climatic regime marked by brutal and aggressive rains, a hydrographic network conducive to the rapid spread of floods and a geomorphological context favorable to flooding floods, as well as waterproofing of land through various economic and development activities ... the Guigou depression of 1227km2 has been subject for several years, particularly during the last decade (floods of 2001, 2002, 2003, 2005, 2008, 2009, 2010) to the several successive floods generated by the overflowing of the floodwaters of the Guigou wadi and the other tributaries It is in this perspective that this work comes with the objective of achieving a hydraulic model by HEC-RAS allowing to limit, on the one hand, flood zones for each return period and, on the other hand, to propose measures to combat the floods caused by the Guigou wadi.
The hydraulic simulation results enabled us to note that the wadi overflows for all the return periods on a good part of the agricultural constructions and plots, which confirms the observations made during the diagnosis of the sections of the study area, as well define the development plans planned at Wadi Guigou, in order to remedy the flooding phenomenon and protect the center of Timahdite and the Guigou plain.
