AbstractABSTRACT The Shatt Al- Arab River between the Sindibad and Umm Al-Ressass islands has been selected as a study area. Four stations were selected to study the bank stability. The geometric dimensions of the banks were measured, laboratory tests comprises; cohesion, internal friction and weight density at the four depths 0-50, 50-100, 100-150 and 150-200cm. Shear stress of each depth has been calculated. The results showed that there are variations in the soil properties of the stations. Soil texture is silty clay. It has been also found that there are variations in the values of natural moisture content, weight density. All of the bank slopes which are selected for this study are in the stable state, but they vary in the degree of stability. Cohesion and for a lesser extent the height of the bank slope play a major role in the determination of bank stability of Shatt Al- Arab. Some equations have been found in this study in order to know the stability state under different conditions which affect the bank slope stability.
