Scour Impact of Coastal Swimming Pools on Beach Systems

Abstract

Swimming pools have become an integral part of habitable coastal construction. These pools frequently increase the turbulance of floodwater during a tropical storm or hurricane. This results in an increase in the scour potential under and around swimming pools. This paper demonstrates that a suitable scour model for seawalls from literature is applicable to coastal swimming pools, including over-topping and corner effects. The model predicts substantial scour around pools for typical storm waves and water levels. Optimum sizing and siting for coastal swimming pools are also discussed.
