Problems solved by technology

[0005] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a tidal tributary estuary water ecosystem and construction method for dewatering the river after the dam, which solves the existing wetland layout in the tributary backwater area, which is often used in wetland technology. Using a single type of wetland, the problem is that the function is relatively single

Abstract

The invention discloses a water ecological restoration system and method for a tidal tributary estuary of a dam-back dehydration reach. The system comprises a first bank slope type wetland, a second bank slope type wetland, a first overflow type wetland, a second overflow type wetland, a first group of wetland hydrological branches, a second group of wetland hydrological branches and gates. According to the invention, the problems that the existing wetland layout about the branch water return area mostly adopts a single wetland type when the wetland technology is used, and the function is relatively single are solved.

Description

technical field [0001] The invention relates to the technical field of ecological engineering, in particular to a tidal tributary estuary water ecological system and a construction method of a dewatering river section behind a dam. Background technique [0002] The tributaries in the dewatering section after the dam are regulated by the dam, and the water volume in the flood period is large. The water flow in the dewatering section changes drastically, and the water level in the river section rises rapidly in a short period of time. There will be water backflow in the dehydration section. The phenomenon of internal tributaries forms a wide range of backwater areas in the tributary estuary area, which is similar to the periodic movement of seawater caused by the gravitational force of celestial bodies. The artificial regulation of the dam makes the tributary estuaries undergo "tidal" changes. The water body presents a reciprocating flow phenomenon. [0003] During the flood ...
