Because a storm surge caused by typhoon 9918 occurred during spring tide, a very serious storm surge disaster occurred along the Inland Sea in Yamaguchi Prefecture on September 24,1999. Field investigations were made at 29 seadikes sites which had been damaged, concentrated especially in the western part of Yamaguchi Prefecture. The total length of the damaged seadikes reached about 2.4 km. At Nishioki in Onoda and at Oki-ube in Ube, the seadikes underwent remarkable destruction due to joint breakage, and consequently the operations of the Yamaguchi-Ube airport and an oil company were completely shut down. These observations suggest the necessity of examining the storm surge brought about by typhoon during spring tide, and calculating effects of the resulting wave force on seadikes.
