Finally, for a given upstream water discharge, the upcoming sediment flux has been assumed to be in equilibrium with the local hydrodynamics. The value of Qs has been estimated by considering
a relatively straight river reach comprised between Sections 57A and 59B (near the town of Calto) and computing the sediment transport rate by means of the Engelund and Hansen relationship [12]. Fig. 5 shows the sediment transport capacity computed with a grain size equal to 0.35 mm, as indicated by the granulometric analyses carried out by ADBPO [2], and considering the bed topography surveyed in 2005 (Fig. 3).
