註釋Field data from a large number of tidal inlets on sandy coasts of the United States were analyzed and a relationshp was established between the tidal prism and the minimum flow cross section of the entrance channel. Other variables make it difficult to determine the effect of grain size on the prism-area relationship. Generally, detailed sampling of bottom sediment is not available, but a summary of samples in the Golden Gate and its approaches shows little range in grain size. This finding indicates flow resistance in that vicinity may be controlled more by form resistance of ripples and sand waves than by grain size alone. To evaluate the effect of grain size more precisely, tests were repeated with different size sand grains and the results of the tests compared. Test procedures and results are presented. (Author).
