AbstractThe work reported in this research presents numerical investigations on the effect of cut-off inclination angle on exit gradient and uplift pressure head under hydraulic structure and determines the optimum location and angle of inclination of cut-off. This problem is solved using the finite element method by using (ANSYS 11.0). It is concluded that using downstream cut-off inclined towards the downstream side with Ө less than 120� is beneficial in increasing the safety factor against the piping phenomenon. The results are evaluated graphically in non-dimensional form.
