Abstract

The invention provides a maintenance beach profile design method for reducing the sandstorm intensity on the beach surface, which includes determining the size of the supplementary sand deposits and the grain size of the supplementary sand deposits in the corresponding area of ​​the maintenance beach, determining the width, slope and elevation of the dry beach of the maintenance beach, and determining Steps to maintain the green windbreaks on the inland side of the dry beach at the rear. The beach profile design method for reducing beach wind sand intensity provided by the present invention can effectively restrain beach wind sand and reduce beach wind sand through reasonable coastal beach maintenance profile and backside windbreak design in strong wind area according to the characteristics of coastal wind sand activities in strong wind areas. Strength, improve the quality of beach conservation. It overcomes the deficiencies of the existing beach maintenance design technology, reduces the wind erosion loss of the beach sediment, reduces the sandstorm effect on the beach, and protects the coastal environment.

Description

technical field [0001] The invention relates to the technical field of beach conservation, in particular to a design method for a conservation beach profile that reduces the sandstorm intensity on the beach. Background technique [0002] The coastal areas of my country, especially the coastal areas of South China, have strong sandstorm activities, and the area of ​​modern coastal sandstorm activities is as high as 2.378×10 5 hm 2 The length of the sandy coast is about 300km. It is a country with very active coastal sandstorms in the world. Since the beginning of the 21st century, with the comprehensive implementation of coastal ecological restoration in my country, more than 100 beach maintenance projects have been carried out. The implementation of the beach maintenance project has increased the sediments on the beach surface and formed a new accumulation unit of sandy landforms, thus expanding the wind area of ​​the beach, increasing the source of aeolian sand, and raisi...
