Rôle des ouvrages de conservation des eaux et du sol dans la lutte contre les inondations

Hamza A., Hamou H.

Different measures should be adopted in order to reduce the impact of floods. For countries like Tunisia characterized by the irregularity of their climate (floods, drought), perfect control of the flow of rivers with violent and frequent floods requires global planning schemes for water and soil conservation. The inventory of the rainy events of 1990 has shown the urgency of the protection against floods of the southern branch of wadi of Zeroud and of the watersheds of wadis of Leben and Baïech. Everything summarized in the foregoing section depends on the relief, the encasement of tributaries and of thalwegs as well as on the texture of the soil. This leads to the optimization of the density of water and soil conservation structures with various aims, in connection with the lamination of the flood and its dispersion and with the conservation of the soil after the passage of the flood.
