Numerical models are frequently used to simulate water flow in hydraulic engineering. shallow water equations are basic governing equations with assumption of the velocity distribution uniformly in vertical, so they have some limitations on the simulation of some plane flows, such as wind - induced flow, curve river flow and flow nearby the submerged dikes. 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
在水利工程中經常需要採用數學模型模擬水流的流態，淺水方程是進行平面流態模擬計算的基本控制方程，但因其忽略了流速垂線分佈的不均勻性，在模擬某些平面流態（如風生流動、河灣水流、潛壩等工程附近的流動）時存在一定的局限性。 -
