Experimental and numerical modeling to investigate the riverbank’s stability

Abstract The purpose of this paper is to assess the failure mechanism riverbanks due stream flow experimentally and numerically avoid recurring landslides by identifying most dangerous place treating them a suitable method. experiments physical models were carried out study riverbank evaluation their stability in two cases: short-term condition long-term where three tested. Tigris River (Iraq) considered as model terms applied velocity modeled soil banks it was used at same characteristics prototype scale. Also, numerical simulation performed using FLOW-3D program determine distribution identify areas subjected high stress levels through water flow. obtained results are inspecting types that occur under influence specific limits velocity, which have shown good compatibility with type In addition calculating amount erosion, angle, settlement investigated also. experimental work well matched, standard error rate for Froude number ranged between (1.8%–6.6%), depth (2.7%–6.9%).
