用准一维的浅水波方程研究了波浪在有阻尼海滩及河道上的传播过程，假定阻尼项是线性的，海滩的深度和河道的宽度随沿波浪传播方向是变化的，导出了解析解，解的渐近结果表明摩阻与浅水效应是明显的．
The quasi-one-dimensional shallow wave equation is used to study the wave propagation on damped beaches and rivers. Assuming that the damping term is linear, the depth of the beach and the width of the river channel vary with the wave propagation direction. Analytical solutions are derived, The asymptotic results of the solution show that the friction and shallow water effects are obvious.
