| Abstract: | According to continuity equation of Saint_Venant, and based on the old corresponding rising difference model, the paper developed a new model of channel flood realtime forecasting. It has only one parameter, which estimated by recursive least square estimation with variable forgetting factors. The new model needs data of only one survey station. The authors applied it to middle reaches of the Yangtze River, the results are satisfactory. |
| Keywords: | rising difference model flood forecasting least square method |
