Abstract

The invention provides a method for repairing an eroded coast plane composite beach, comprising the following steps: dividing the shoreline into several sub-units; obtaining the effective breaking wave height H in the sub-units b and breaking wave angle θ b ;Calculate the coastal net sand delivery rate of each subunit and the sandstone particle size of each subunit; fill each subunit with sand and gravel according to the coastal net sand delivery rate and sandstone particle radial direction, and regularly transport the downstream sandstone to the upstream. The planar composite beach restoration method for eroded coasts provided by the present invention fully considers the different coastal net sediment delivery rates of strongly eroded shore sections and weakly eroded shore sections, divides the entire coast into several sub-units and performs composite design, broadening the traditional beach The range of conservation is also applicable to areas with relatively severe coastal erosion, which greatly promotes the improvement of strong erosion coastal protection capabilities and the improvement of landscape effects, and achieves the goal of significantly reducing the net sand transport rate along the coast with different particle sizes along the coast.

Description

technical field [0001] The invention relates to the technical field of beach maintenance, in particular to a compound beach restoration method for eroded coast planes. Background technique [0002] At present, one-third of my country's coast has suffered or is suffering from coastal erosion. As an ecological "soft" protection, beach maintenance is gradually becoming a powerful tool to prevent and control coastal erosion. Domestic beach restoration often maintains the stability of the beach by constructing "static headlands", but this method is only suitable for coastal sections with a small net sand discharge rate, or requires the construction of a large number of "hard" ancillary works , such as building offshore breakwaters. The construction of these hard ancillary works will not only seriously affect the local landscape effect, but also change the local hydrodynamic conditions and have a greater impact on the marine ecological environment of the adjacent sea area.
