波による砂床断面変形に関する実験結果 A Study on Sand Slope Section Shape's Changes by Waves Attacking Kubo, Satoshi 1904 久保, 敏 40372057 クボ, サトシ Kataoka, Kei 片岡, 慶 カタオカ, ケイ Fujihara, Masayuki 3527 藤原, 正幸 フジハラ, マサユキ The tests that 1/10 gradient sand slope is attacked by waves for 100 hours, were done by making use of two dimensional tank. As a result of these tests, the following points were made clear. 1) The section shape of this sand slope changes as time goes by. 2 ) The shore side was eroded, and the eroded sand was accumulated at offing side. 3) There is a point in which the depth changes little between eroded and accumulated parts. 4) The depth(h) depends on the wave height(H0) and the wave Length(L0). 5 ) At the section shape, the area of the deposit continues to increase for 100 hours. 6) When the area (S) is expressed by lapse time (t), namely S=A0+A1·t (S: area of the deposit, t: lapse time (hour)), then either A0 and A1 depends on H0, L0 and wave cycle (T). article 水産工学研究所 National Research Institute of Fisheries Engineering 1991-03 水産工学研究所技報. 水産土木 13 15 23 Technical report of National Research Institute of Fisheries Engineering.
