The reason to creates this kind of destruction to be very many, the main of them is that the apron partially has not been able fully to display it to eliminate energy affect so causes the ditch bed to wash out, forms flushes the pit, leading to the apron, to guard against flushes the trough and both banks slope protection destruction, for a long time, disappear power design of plunge basin and layout have been focused on disappear power. but not to give the enough value on uses the sea to inundate the section to disappear power and adjust speed to reduced downriver washes out
水閘閘下沖刷破壞的部位絕大多數發生在消力池下的海漫和防沖槽處，造成這種破壞的原因很多，其中很大一部分是由於海漫部分未能充分發揮其消能作用而引起渠床沖刷，形成沖坑，導致海漫、防沖槽及兩岸護坡的破壞。一直以來，人們把消能的研究重點放在消力池的消能設計及平面布置上，而對海漫段消能及調整流速功能研究甚少，至於對海漫加糙水流運動建立數學模型，在國內外還很少見相關的論文資料。
