A laboratory study of the effect of varying beach slopes on bore-driven swash hydrodynamics

Swash zone hydrodynamics has significant coastal geomorphological and engineering implications. However, there is still a research gap in fully understanding the response of bore-driven swash to varying beach slopes. Therefore, this study, laboratory experiments were performed flume investigate flows over impermeable smooth beaches with mild slope (1:35), steep (1:10), composite (1:35–1:10), respectively. The designed events are produced by collapse dam-break-generated bores. Wave gauges, ultrasonic displacement sensors, acoustic Doppler velocimeter, particle image velocimetry used simultaneously capture different phases (bore collapse, uprush, backwash) bore evolution entire zone. impacts on view shoreline movement, depth, velocity first analyzed. formation vortex structure three also reported study.
