波高是指相邻的波峰和波谷间的垂直距离。通常以H表示,如图。在工程、预报等应用中,通常根据上跨零点定义波高。对于定点观测的海浪波面记录中,波高为上路零点一侧的显著波峰与另一侧的显著波谷间的高度差。
On the flume experiment, Wave Height Sensor is used to measure the wave height and period at different locations. NDV is used to measure the scour depth real time and three dimensional instantaneous velocities.
水槽试验中,用浪高仪测量不同位置的波高、波周期,通过分析这些数据,了解波浪在斜坡前的反射、传播过程中的变形和墩柱前的反射、绕射,分析波浪场的改变对局部冲刷的影响。

海啸可能达到的波高向来很难估计-海浪可能根本无法到达,或者可高达超出海平面10米。

仙台市是日本宫城县一个人口接近一百万的城市,被一波高达20英尺的巨浪袭击后,又被一波33英尺高的巨浪冲击。
Sendai, a city of 1 million in Miyagi prefecture, was struck by a wave 20 feet high and then another 33 feet high.
为减少码头前沿的反射波高,巧妙地在卸荷板和胸墙中设置进、出水孔和消浪室。
Water inlet&outlet and wave breaking chambers are arranged for relieving slab and breast wall to reduce the reflected wave height alongside the berth.
And all we mean by constructive interference is that literally those two waves add together, such as the maxima are now twice as high, and the minima are now twice as low.
相干相长,相干相长也就是,说两个波加在一起,所以最大值变成2倍那么高,最低值变成2倍那么低。
And what is plotted below is the actual wave function, so you can see it starts very high and then the decays down.
下面这画的是,波函数,你们可以看见它开始非常高,然后衰减下来。
Then you get successively deeper, II through IV, slow, irregular, high amplitude delta waves, and then once you reach stage IV you start going up again, up through stage III and II.
然后睡得越来越深,从第二到第四阶段,慢,不规则,高振幅的δ波,等你到达第四阶段,你又开始返回,第三阶段和第二阶段。
