  • Low-energy coastal beach restoration method
    Patent number: 11519147
    Abstract: The present invention provides a low-energy coastal beach restoration method, comprising: constructing a convex beach berm, determining an aspect ratio of the beach berm edge, determining a beach face slope, performing sand replenishment, determining the dredging zone and dredging depth, and determining the steps of building a sediment groin. The present invention utilizes the feature of the convergence effect of the wave energy on the headland, artificially constructs a convex headland shaped beach berm, and determines the required beach face range and slope according to the convex beach berm edge. During beach restoration, dredging around the beach face, while reducing mud sources and increasing the nearshore water depth, it also builds a convex nearshore terrain, which effectively increases the wave energy at the restoration site and improves the coast muddy situation of low-energy coasts.
