抄録

Recently the field survey, the model observation, and the numerical simulation are reported for countermeaserment of pollution in Omura Bay. It's seems that the best way for the improvment of pollution in Omura Bay is to introduce the new sea water from outer sea to Omura Bay. The numerical simulation technique is used for the analysis of tide in Omura Bay, the results obtained are as follows. If the flow rate of new sea water introducing is one hundred million tons per a tidal cycle, the mean sea level rises a 15 cm in hight by the introduced water, but the oscillation amplitude of tide is not changed. The tidal current is little change at the center and the north parts in the bay. In the proximity of the introducing point of the new water and south west part, the value of velocity and the phase of tidal current are change. In whole region of the bay, it is seemed that the permanent tidal flow has a little increment, as results of new water introduced.
