Abstract

The invention discloses a beach-area constant-flow water supplementing system and method. The beach-area constant-flow water supplementing system comprises a water storage pool, a constant-flow waterreleasing subsystem and a uniform outflowing subsystem. The constant-flow water releasing subsystem of the beach-area constant-flow water supplementing system can automatically adjust the height of aweir plate according to the change of the water level of the water storage pool to keep the weir head constant, and thus the outflow rate is kept constant; meanwhile by being matched with the uniformoutflowing subsystem, the water level can be kept to uniformly flood beaches at the set overflow depth; therefore manpower and material resources are effectively saved, the beach-area water supplementing efficiency is improved, the benefits are increased, and meanwhile the problems of beach-area scour erosion and small beach land water supplementing covering area caused by direct water releasing for beach flooding are avoided; and the system is easy to operate and high in automation degree.

Description

technical field

[0001] The invention belongs to the technical field of ecological water replenishment in floodplains, and in particular relates to a constant-flow water replenishment system and method for floodplains. Background technique

[0002] A delta, or alluvial plain of an estuary, is a common landform. The silt and other impurities carried by the rushing rivers meet the seawater with a much higher salt content than fresh water at the estuary, flocculate and deposit, and gradually become new wetlands on the banks of the estuaries, and then form delta plains. The top of the delta points up the river, and the outer edge faces the sea, which can be seen as the "base" of the triangle.

[0003] With the development of economy and society, in order to prevent floods, many rivers entering the sea have built flood control dams. Although this protects both sides of the river in the delta region from the threat of floods, it also causes the beach in the delta to lose the chan...
