COMPARATIVE STUDY OF STORM SURGES IN A BAY INDUCED BY TYPHOONS WITH QUICK INVERSION IN WIND DIRECTION. (2014). Coastal Engineering Proceedings, 1(34), currents.24. https://doi.org/10.9753/icce.v34.currents.24

Abstract

Three events of storm surge which yielded different tidal departures in the head of Mikawa Bay, Japan are compared and discussed from the viewpoint of response to the wind forcing. The mechanism of sudden sea level rise is investigated based on the data of wind, sea level and velocity obtained in the period of three different Typhoons which passed near the bay. The magnitude of preceding east wind which gives rise to the sea level in Ise Bay and quick inversion in wind direction from east to west are key factors to the development of large tidal departure in the head of Mikawa Bay. The propagation of surge waves as a free long wave is confirmed through the velocity profile data and also tested using a 2D simple numerical model.
