波高と潮位の出現頻度を考慮した沿岸掃流漂砂量の鉛直分布関数の算定

Depth distribution of expected longshore bedload transport was shown by easy function of beach slope and wave parameter at the wave breaking point. It was calculated from the bedload transport based on physical calculation of regular wave and flow, by the probability operation using the occurrence rate of wave height and tide level. Moreover, the variances of the depth distribution of longshore bedload transport by tidal range, mean wave height, wave period and wave direction were shown. For use of actual prediction, it is necessary to use the depth distribution after consideration of the seasonal or monthly occurrence rate of wave height and wave direction.
