Background
The coastal zone is positioned at the junction of ocean, land and air, is a very sensitive zone, and is very easy to cause unbalanced silt collection and distribution of the coast under the influence of wind, wave, tide, flow and human activities, so that a series of coastal erosion phenomena such as coastline retreating, beach erosion and the like are caused.
For a long time, the coastal erosion degree is aggravated by a series of human activities and natural disasters which are difficult to predict, and relevant scholars do a great deal of work aiming at erosion phenomena of different erosion, so that scientific basis is provided for protection and repair of coastal zones. The relevant theoretical research conditions of coastal erosion in recent years at home and abroad, including coastal erosion mechanism, erosion reason and harm, are briefly described and discussed, the method for coastal protection and restoration is explored, and corresponding thinking is provided from the aspects of research methods, means and the like.
The sand beach of the coast is generated by accumulation of sand supplied from a river on land, a sand dune on the coast, and the sand supplied in a natural state is balanced with a phenomenon in which sand runs into the sea due to waves, so that the sand beach is maintained.
On the other hand, coastal sandy beach is not only in terms of environmental protection but also in terms of popularity in various ocean leisure sports, and the importance of this is also becoming prominent as a sightseeing resource, but because the shoreside of a river is buried or blocked by a concrete dike in river regulation works, the amount of sand flowing into the sea is drastically reduced due to the reduction of natural greenbelts caused by urban facility construction, the disappearance of coastal sand dunes caused by the burying, and the like, and the phenomenon of the reduction of the coastal sandy beach occurs.
According to the bank protection mode, the waves are pushed to the bank protection to scour the front of the bank protection, and sand loss cannot be prevented. The manual beach maintenance method in which sand is artificially input not only requires a large amount of expenses for sand collection and transportation but also is not a fundamental measure for preventing sand loss, and thus has a burden of continuously supplying sand.
