![]() The purpose of this paper is to assess the failure mechanism of riverbanks due to stream flow experimentally and numerically to avoid recurring landslides by identifying the most dangerous place and treating them by a suitable method. The results of experimental work and numerical simulation were well matched, where the standard error rate for Froude number ranged between (1.8%-6.6%), and the flow depth between (2.7%-6.9%). In addition to calculating the amount of soil erosion, the failure angle, and the amount of soil settlement at the riverbank model is investigated also. The obtained results in this paper are inspecting of failure mechanism types that occur under the influence of specific limits of flow velocity, which have shown good compatibility with the type of failure in the prototype scale. Also, a numerical simulation was performed using the FLOW-3D program to determine the velocity distribution and to identify the areas subjected to the high stress levels through the water flow. ![]() The Tigris River (Iraq) is considered as a model in this paper in terms of the applied velocity and modeled soil of the banks it was used at the same characteristics in the prototype scale. The experiments and the physical models were carried out to study the failure mechanism of riverbank and evaluation of their stability in two cases: short-term condition and long-term condition flow where three models were tested. The new model can therefore be used to determine the geometrical parameters of the failed blocks of riverbanks subject to planar failure. Based on a comparison of these errors with those derived from a range of existing equations, we show that this represents a considerable improvement relative to prior studies. Based on observations from field and laboratory tests, we found that the new model provides a mean relative error (MRE) of 4%, 23%, and 27% between calculated and observed values of failure plane angle, tension crack depth, and bank-top retreat, respectively. The estimated tension crack depth is then used in a bank stability analysis, from which the failure plane angle can be evaluated. This is achieved by employing a combination of field and laboratory data to first derive a set of empirical curves to estimate the tension crack depth. In this paper we introduce a new analytical method to estimate the failure plane angle. To reliably analyze the stability of riverbanks against planar failures many parameters (including the failure plane angle and the depth of the tension crack) have to be determined.
