Abstract: A huge retreat on Tigris Riverbanks of Numaniyah-Kut reach was recently investigated in Southeast Baghdad, Iraq. Riverbank retreat due to both fluvial erosion and geotechnical failure was recently predicted from bank stability and toe erosion model (BSTEM). The goal of this paper was to compute Tigris Riverbanks stability for three sites (A, B, and C) along Numaniyah-Kut reach using BSTEM with two different scenarios. The first scenario was assumed that the bank layers were varied by three different soil moisture contents. The second scenario was assumed that the whole bank was varied by three different soil moisture contents. Field measurements were performed along Numaniyah-Kut reach included; soil samples, river cross-section surveys, and hydrological measurements. Specimens acquired from the sites were laboratory tests to obtain geotechnical and fluvial parameters in order to apply the two scenarios. Dry and optimum soil moisture contents obtained more erodible banks compared to wet banks. The results also showed that both scenarios indicated that sites B and C were more erodible compared to site A. In general, banks are more erodible and more unstable at downstream of Numaniyah City in compared with upstream of Kut barrage.
