Extensive Model of Stability Analysis of Riverbanks

Riverbank erosion, land loss and associated sedimentation arc river engineering and water resources management problems of global significance. The ability to predict riverbank stability on eroding rivers is the prerequisite of developing a channel width adjustment model and is essential for estimating riverbank erosion and associated sedimentation. In this research. a detailed model for stability analysis of riverbanks is introduced. Contrary to most available models developed based only on one type of planar or rotational failure, the new model ineludes both these types of failure, providing the ability to analysis bank stability using other available methods and compare the results. Furthermore. this new, unique model has the ability to analyze riverbank stability against cantilever failure. The most suitable analysis method was first selected based on bank material characteristics and stratification and the height and slope angle of the riverbank. The stability of the riverbank was then analyzed based on probable failure methods. The application of the new model providing examples of different types of failure is described
