My trainer told me to get some practice in the shoalingwater, but I was still afraid and my foot retreated the moment it touched the water.
教练让我先去浅水区练习，可我还是非常害怕，脚一碰水就像触电似地缩了回来。

The maximum value of positive and negative horizontal velocity increases gradually with the decrease of the water depth in the shoaling process.
另者，孤立波的边界层速度于浅化过程中正向与负向的极值速度有逐渐增加的趋势产生。

In the course of the propagation of deep water waves to the shoal water zone, the distribution of the surface elevation and the wave spectrum will be changed due to shoaling effect.
