Dynamic pressures on curved front seawall models under random waves

摘要

The shoreline erosion is a major problem that persist world wide and seawall still remain as one of the most widely adopted coastal protection structure. The design of an efficient seawall should be such that overtopping is minimized even during coastal flooding and extreme events by maintaining its crest elevation as low as possible. This can be obtained with curved front face sea walls. Two such curved configurations have been chosen for the study. The experimental investigation on dynamic pressure variation along the surface of the seawall models placed over a bed slope of 1 in 30 and subjected to the action of random waves following the PM spectrum were conducted. The results on the variations of dynamic pressures on the seaward face of both the models along the relative depth are compared and discussed.
