| Abstract: | A formula is deduced for the velocity induced by the vortices in two-dimensional shallow water flows and it is used to correct the Biot-Savart law. The dynamic characteristics of vortex motion in two dimensional shallow water flows are analyzed and the comparison of vortex motion in shallow water flows with the vortex motion in compressible flows are made. |

| Keywords: | two-dimensional shallow water flows compressible flow vortices velocity induced by the vortices |
