针对黄河吴堡龙门区间(吴龙区间)洪水陡涨陡落的洪水特性和多支流的水系特点,采用马斯京根分段连续演算法模拟黄河吴龙区间洪水过程,建立了基于先合后演法的洪水演算方案,给出了分段初始流量确定方法,并制定了支流洪水处理方案,采用实测期与预报期实测洪水资料率定和检验参数,结果表明洪水模拟精度较高。 Aiming at the characteristics of flood and steep falling of the Yellow River Wulong gantry (Wu Long interval) and multi-tributary water system, the Muskingum section continuous algorithm is used to simulate the flood process of the Yellow River Wu Long section, This paper presents a method of initial flow calculation of sub-section, and develops a scheme of flood treatment of tributaries. The flood data rate and test parameters measured in actual and forecast periods are used. The results show that flood simulation accuracy is high.
