洪水演进計算目前常用的有經驗槽蓄法、抵偿河长法和馬斯京根法等,而馬斯京根法应用更为广泛。但馬斯京根法用线性的槽蓄方程来代替曲线方程,造成一定誤差。我們曾将槽蓄方程改用为的冪函数,即 Flood evolution is commonly used in the calculation of the empirical trough storage method, offset the river law and Muskingum method, while Muskingum root method is more widely used. However, the Muskingum method uses a linear tank-storage equation instead of the curve equation, resulting in some error. We have switched the tank equation to a power function, that is
