台風7617号による鏡川下流部の流量,水位と潮位との関係

Abstract

Kochi City had suffered from a flood caused by the heavy rain fall accompanied with7617 typhoon, September, 1976. The River Kagami is one of the important rivers inKochi City which includes Kochi Harbour and Urado Bay in Shikoku District, westJapan.This paper reports an estimate of the flooding discharge at the down reach of theRiver Kagami to relate the flooding vestiges on the bank of the River Kagami withthe the estimated discharges of the other rivers and of the estimated tidal currents inUrado Bay. The effect of the flooding discharge is also evaluated to separate thepredicted astronomical tide level at Katsurahama in the mareograms which are obtainedin Urado Bay.
