Abstract

Abstract

A set of 2D wave flume experiments on a sandy beach were performed to investigate the morphological response of sandy beach to the wave dynamic factors causing sea-level changes. The initial 1/10 simplex beach slope was exposed to the following different wave actions,i.e.,cnoidal waves,irregular waves,regular waves and solitary waves actions,and three different experimental water depths were used to simulate the sea-level change. This study measured a series of free surface elevations for different waves at the time of wave propagation,wave breaking,uprush and backwash,and cross-shore beach profiles after undergoing wave actions. The results showed that the equilibrium beach profile showed wide high berm topography after undergoing cnoidal waves,irregular waves and regular waves,and yet it became sandbar form topography after undergoing solitary wave action. The equilibrium profile shapes were essentially unchanged but moved shoreward under sea-level rise,and the position of berm,trough,sandbar and the retrograde distance of shoreline show good correlations under the four different wave actions.
- beach profile evolution,
- wave,
- sea-level rise,
- fractal method,
- Bruun rule
