| Abstract: | In this paper, the boundary-integral equations of plane, free overfall are derived by using the Riemann-Hilbert mixed boundary value problem technique and conformal mapping. Numerical calculation shows that the calculation in the physical plane is superior to those in the auxiliary plane. This numerical procedure demonstrates good convergence with a small calculating time, and the results agree well with those empirically measured. |
