| Abstract: | Based on the expanded Saint Venant equation and f inite difference equation, rational coding of river network is conducted. Preiss mann Method is adopted in discretion of the Saint-Venant equation. Computer pro gram is compiled by using three-level solution method of network matrix identif ication to solve the water level Z and discharge Q at different cross s ections. |
