河流泥沙数学模型的研究分析

Study on the Mathematical Modei of River Sediment

泥沙数学模型是预测水沙运动和河床演变的重要手段之一。对一维数学模型、二维数学模型的基本原理、计算方法、关键技术处理等方面分别进行研究,分析黄河泥沙数学模型的应用,指出泥沙数学模型的发展方向。

The mathematical modei of river sediment is the important method for predicting the movement of river sediment flow, river evolution and regulation laws. This article makes study on the calculation formula and the key technology for 1 - D mathematical modei and 2 - D mathematical model. It also analyses the application for the mathematical modei in re-lation to the Yellow River and points out the direction that the mathematical modei might follow in development.
