本文利用径流过程的灰色模型,建立了洪水过程退水段的预报程序。经实际使用,效果良好,现介绍如下。1.模型简介一次洪水过程,按峰顶可将其划分为涨水段AC和退水段CB,见附图。经研究表明,退水段具有指数曲线规律。 In this paper, we use the gray model of runoff process to establish the forecasting program of the flood section of the flood process. After the actual use, the effect is good, are presented below. 1. Introduction to the model A flood process, according to the peak can be divided into the water section of the AC and the backwater section CB, see photo. The study shows that the backwater section has an exponential curve.
