For above-mentioned reasons, Extended shallow water equations are developed by introduction of momentum coefficient, correction of convection and bed resistance in equations of motion. One extended shallow water equations for submerged dike are researched emphatically.
为此,本文从水流运动的基本方程、浅水流动这些基础概念出发,通过动量系数的引入,修正二维浅水方程组中动量方程的对流项和底部摩阻项,建立了广义浅水方程的基本形式,并重点研究了一种适用于潜坝平面流态模拟的广义浅水方程。
