Coupling effect of suction variation on riverbank stability

Failure of riverbank slope is a common problem in tropical country like Malaysia. Problems are often encountered when calculating the real factor safety of riverbank slope due to varying rainfall intensity and fluctuating of surface water table applied on the slope. In this study, the coupling effec...

description Failure of riverbank slope is a common problem in tropical country like Malaysia.
