Abstract

After the implementation of the beach nourishment project, some environmental issues come up accompanying with the function of mitigating beach erosion and protecting the coast. Especially in the coast with strong wind, nourishment alters the environmental factors of beachface, which significantly impact the characteristics of aeolian sand transport and wind-blown sand flux. To study the aeolian sand transport and sediment accumulation after beach nourishment, Longfengtou beach in Pingtan Island, Fujian province, has beach taken as a typical study area. It is indicated that the beach characters such as dry beach width, surface sediment grain size, surface moisture and beach elevation, have significant impacts on beach aeolian sand transport and deposition process. The main conclusions of this study are showed as : (1) the increase of dry beach elevation enhance the wind speed of beach surface, which improves beach surface aeolian sand transport rate and wind-blown sand flux; (2) the elongation of dry beach width of nourished beach increases the fetch and provides sufficient sediment resource for aeolian sediment transport, and also elongates the duration of sediment transport; (3) after nourishment, the lower sediment moisture of beach surface decreases beach sediment transport threshold velocity and reinforces beach surface aeolian transport.
