Description :
Riverbank erosion, associated sedimentation and land loss hazards are a land management problem of global significance and many attempts to predict the onset of riverbank instability have been made. In this paper, a rational, physically based method to predict the location of tension cracks on the floodplain behind the eroding bank ace is presented and tested. A case study is used to illustrate the computational procedure required to apply the model. Improved estimates of failure block geometry using the new method may potentially be applied to improve predictions of bank and floodplain land loss.
