Geomorphological response of sandy beach to tropical cyclones with different characteristics

Tropical cyclones (TCs) play important roles in the evolution of beaches. The response beaches to a single tropical cyclone (TC) has been well reported, however, few studies have compared responses same beach TCs with different characteristics. Taking Haiyang Beach northern China Seas as case study, profiles before and after two TCs, Lekima Bavi, which passed through west east sides study area, were investigated. exhibited erosion at upper foreshore minor deposition near mean high water level (MHW) subaqueous sandbars formed nearshore zone, whereas all showed little changes Bavi. A high-resolution FVCOM model was established eleven sensitive experiments conducted simulate hydrodynamic induced by tracks, intensity duration. Then Xbeach used display due conditions. It is found that significant storm surge strong seaward bottom current landward wind side area should responsible for profile changes. Negligible rise related eastern path can only result change beach. Swell contributes most wave height while less effect on In this we conclude effects are primarily dependent relative position TCs’ tracks.
