摘要

Caoejiang River is a tidal river and its hydrological system is unique as the water-stage continually changes under the interaction of upper reach flood waves and downstream tidal waves. Consequently, the calculation of water-stage in the cross-section of Caoejiang River is very complex. The bi-directional Muskingum water-stage routing model separates the hydrologic processes of the tidal river into upper reach flood and downstream tidal waves, respectively. The Muskingum water-stage routing method was first used to calculate the propagation of the flood and tidal waves and then routed stages are summed by using different weight factors. All the parameters used in the model can be adjusted automatically or determined manually. The model was applied in the Caoejiang River, China, to evaluate the tidal effect on the streamflow of different sections. The results show that the model can be applied successfully with high accuracy and reliability for the water-stage forecasting in Caoejiang River, and few parameters are needed for model calibration, displaying the relative advantage of the model.
