| 摘 要： | 在ECOMSED数值模式的水动力模块基础上,引入了动边界处理技术,建立了数值试验,并采用单一斜坡地形和圆形浅滩斜坡地形对该技术进行了验证。数值试验结果显示,改进后的水动力计算模式可成功再现由涨落潮引起的潮间带漫滩现象,而且模拟得到的水面线较为光滑,且未产生零水深和负水深。

| Abstract: | On the basis of the hydrodynamic module of ECOMSED program,an inundation scheme was developed.Two numerical experiments,including a single-slope beach and a sloping circular shoal,were applied to test the proposed inundation scheme.The results show that the inundation phenomenon caused by tidal flood and ebb process can be successfully reconstructed by the usage of this scheme,and the water surface profile obtained by simulation is smooth,which do not generate zero/negative water depth. |
