Abstract: | An explicit numerical algorithm for solving two-dimensional system of shallow-water equations is presented. The algorithm is based on the control volume method with recording mass and momentum fluxes through the faces of the volume with the use of an approximate solution of the Riemann problem. A numerical solution is compared with analytical solutions for a flow over a bottom step and with data of laboratory experiments in a flume with a sloped bed or a bed with an obstacle.__________Translated from Vodnye Resursy, Vol. 32, No. 3, 2005, pp. 282–294.Original Russian Text Copyright © 2005 by Prokof ev. |
