“…The phenomenon of sediments reaching the dams every year has prompted many researchers who have tried to solve this problem with several methods. In this context, we mention the works of Tixeront [1], Capolini [2], Ghorbel and Claude [3], Heusch [4], Milliman and Meade [5], Sogreah [6], Demmak [7], Colombani [8], Walling [9], Probst and Suchet [10], Lahlou [11], Rais and Abidi [12], Albergel [13], Snoussi et al [14], Merzouki [15], Moukhchane et al [16], Meddi [17], Bouraba [18], Remini and Avenard [19], Remini [20], Terfous et al [21], Ghenim et al [22] Megnounif et al [23], Bouanani [24], Dechemi et al [25], Achite and Touaibia [26], Touaibia et al [27], Marouf and Remini [28], Marouf [29],who have studied some Algerian, Tunisian, and Moroccan basins. In reality, the problem is very difficult, complex and far from being solved with the current theoretical formulas.…”
