From knowledge of wind resistance coefficients measured over the sea, it is possible to compute the shear stress of a wind field on its surface Where a body of water is relatively shallow, such a shear stress will transport water to the downwind end and so create a high water level or surge Graphs are presented for ready application of the relevant formulae to cases of lakes and Continental Shelves The wind fields of either uniform or triangular horizontal distribution in velocity are included, as well as conditions of stationary or moving fetches Surges from seven typhoons travelling towards Hong Kong are computed and compared to actual records.
