Abstract: With the rapid development of urbanization，the flood safety of urban rivers is becoming more and more important.In order to improve the river flow and the fluctuation of the water level，the river channel needs to be regulated.Taking the inner river and its northern branch in Hunchun City as an example，this paper uses MIKE21and HEC-RAS models to simulate the current situation and the designed water surface of the river.The results show that under the flood peak flow，the designed river channel significantly reduces the water level，which is more conducive to the flood control safety of the river.In addition，recommendations are made for the suitability of the 1Dand 2Dhydrodynamic models used.

摘要： 随着城市化建设的快速发展,城市河流的行洪安全愈发地更为重要,为改善河道水流不畅、水位局部起伏变化的情况,需对河道进行整治。文中以珲春市内河及其北支为例,分别利用MIKE21和HEC-RAS模型对其现状和设计河道的水面线进行模拟推求。结果表明,在洪峰流量下,设计河道明显降低了水位,利于河道的防洪安全。此外,对所用的一维及二维水动力模型的适用性作出建议。
