名古屋港および明石川河口付近における潮流の二,三の特性

Abstract

The disasters at coasts are caused not only transient phenomena, I. E., storm surge andtsunami, but also by local scour and deposit by steady coastal currents and by artificialchange of coastal line.This study has been carried out to obtain some fundamental data of them, I. E., this studyis on coastal flow and the related phenomena at Nagoya Harbour and the coast near AkashiRiver. At the two regions, coastal f1ow consists mainly of tidal currents. Bottom frictions andeddy viscosities are calculated and derived from the data of tidal observations at the regions, which seem to show some characteristics associated with tidal currents.
