Abstract

Field measurements have been carried out at the mouth of the Nanakita River in Japan. The maximum velocity at the throat section was kept constant, 1 m/sec, although the river mouth topography changed much rapidly in a week. It therefore seems that the equilibrium condition at the river mouth can be expressed in terms of the maximum velocity. The wave set-up height measured in the river mouth was also analyzed and was found to be responsible for the intrusion of sand into the mouth.
