Evaluation Method of Suction Rate of Backfilling Materials from a Coastal Dike or a Seawall

摘要

Evidence shows that coastal dikes and seawalls could be damaged ordestroyed by coastal scours and the suction of backfilling materials. Asthe impacts of coastal erosion and global warming become severer, it isnecessary to be able to predict the suction rate of backfilling materialsfrom underneath a dike or a seawall with sufficient accuracy.Therefore, this research paper proposes a method that can predict thesuction rate of backfilling materials from a dike or a seawall. Thefindings show that the estimates of the suction rate using the proposedmethod were very similar to the measured field data. This factindicates that the proposed method can predict the rate of suction withsufficient accuracy.
