Tsunami wave speed deep vs shallow water

WebTherefore, a wave’s size depends on wind speed, wind duration, and the area over which the wind is blowing (the fetch). This variability leads to waves of all shapes and sizes. ... An … WebThese waves are called shallow water waves. For large kH, which will occur for short wavelength waves, the function can be approximated by a line with slope = 0. In this case, where , the phase speed is approximately. The dispersion relationship is , which has first derivative, These waves are called deep water waves.
