Abstract
Recentry it has been necessary the purification of mooring basin water in fishing ports for new use, such as stock of fishes in living or intermediate breeding. The authors proposed a new method for interchanging sea water in which fresh sea water is drawn into the port by raising the mean water level through the wave breaking process over the submerged mound. A hydraulic model test was executed to prove this method to be useful for interchanging sea water and to present appropriate profile and plane designs such a structure .
