大阪市内河川の高潮遡上に関する水理模型実験 ―防潮水門建設に伴う高潮の堰上高―

Abstract

Constructions of five storm surge gates, which prevent storm surges running up inrivers and canals in Osaka City, were planned a year ago in order to protect Osaka Cityfrom the disaster of inundation. However, there was a care of piling-up of water bystorm surges at the down stream side of the gates. This study is to give a reasonableand quantitative estimation of the piling-up of water.At first, reproductivity of the past storm surges was tested in a hydraulic model ofthe main rivers in Osaka City, which was proved to be successful. After this test, the effect of the storm surge gates on piling-up of water by storm surges was investigatedby the model.
