| 摘 要： | 针对天然河道中常出现水位随流量变化并导致流动区域发生变化的这种现象，利用ＡＤＩ（ＡｌｔｅｒｎａｔｉｎｇＤｉｒｅｃｔｉｏｎＩｍｐｌｉｃｉｔＭｅｔｈｏｄ）法，融入迎风有限差分格式离散基本方程，利用迭代法求解差分方程组，并采用大清河实测水文资料，对模型进行了验证．证明了该模型能成功地求解出天然河道平面流场的形态以及河道的冲淤状况．

| Abstract: | The flow guautity vaviation leads to the change of water level in the river. so the area that water covers too. The condition the authors utilize the method of ADI(Alternating Direction Implicit Method)and finite difference to solve the basic equation. The mathematical model is verified by the hydrology test data of Daqinghe in Hebei province.The status of the fluid and the erosion or silt in the river are solved by the above methe matical model. |
