More Information
Summary:The present invention provides a nourished beach profile design method for reducing aeolian sand transport intensity over the beach, comprising the steps of determining fill sediment in the corresponding area of a nourished beach and the grain size of the fill sediment, determining the width, slope and elevation of a dry beach of the nourished beach, and determining green windbreak zone on an inland side of a backshore dry beach. Focusing on the active characteristics of aeolian sand transport in strong wind coast, the nourished beach profile design method for reducing aeolian sand transport intensity on the beach provided by the present invention can effectively inhibit aeolian sand activity over the beach face, reduce beach aeolian sand intensity, and improve nourished beach quality via a reasonable coastal beach nourishment profile design in strong wind coast. It overcomes the shortcomings of the existing nourished beach design technology, reduces the wind erosion loss of beach surface sediment, reduces the effect of aeolian sand activity over the beach face, and protects the coastal environment.
