| The variations of water surface elevation due to bridge are studied using one_dimensional dynamic wave equation. The preissmann scheme is used to solve the dynamic wave equation and the bridges was treated as internal boundary conditions. Main causes of bridge backwater are the proportion of the contracted area due to bridge, roughness coefficient and discharge coefficient. The effect of discharge coefficient in weir flow condition is comparatively small. This model is verified by applying to the Suyoung River. which suffered a severe damage by typoon Gladys. The rise of water level through bridge is 1.53-1.08m in the reach of 4.25-6.20km from the downstream of river. The simulation results of the model have good agreements with the observed data. |
