随着黄河清水来源区基流的减少、中下游地区耗水量的增加，使近十几年黄河下游中小洪水、高含沙洪水出现机率增加，从而导致一些迎送溜关系较好的控导工程对河势的控导作用明显削弱。小浪底水库建成后，将改变进入下游的水沙及洪水过程，中小洪水持续时间将更长，今后游荡性河道如何整治是一个非常重要的课题。本文通过模型和原型资料的对比，对已建整治工程布局中存在的问题及工程对中小水的适应性等进行了分析，同时对新形势下游荡性河段河道整治设计流量、设计河宽及新型河道整治工程状况下排洪河宽的计算等问题进行了分析和初步评议。
With the decrease of base flow in the source region of the Yellow River and the increase of water consumption in the middle and lower reaches of the Yellow River, the probability of medium and small floods and high silt floods in the lower reaches of the Yellow River increased in the past decade, resulting in some good control projects The role of river control significantly weakened. After the completion of Xiaolangdi Reservoir, it will change the process of entering and leaving the water and sediment into the lower reaches. The duration of small and medium-sized floods will be longer. It is a very important issue for how to regulate the wandering river in the future. Based on the comparison between the model and the prototype data, this paper analyzes the existing problems in the layout of the rehabilitated works and the adaptability of the project to small and medium-sized water. At the same time, this paper analyzes the design flow, New type of river regulation project under the condition of flood discharge river width calculation and other issues were analyzed and preliminary comments.
