Method for creating ecological wetland to promote water body exchange of encircling type harbor basin or harbor

Abstract

The invention provides a method for creating ecological wetland to promote water body exchange of an encircling type harbor basin or harbor. A water storage water area is established nearby the harborbasin and communicates with seawater, a gate is arranged on the side, and a water body channel is arranged between the water storage water area and the harbor basin or harbor. During flood tide, thegate is opened, and the seawater flows into the water storage water area. During falling tide, the gate is closed, the seawater flows into the harbor basin or harbor from the water storage water areato form harbor penetrating flow, and the polluted water body in the harbor basin or harbor is driven to flow out of the harbor basin or harbor. The natural power of tide fluctuation is utilized, wateris stored in the water storage water area during flood tide, the water body in the water storage water area flows into the harbor basin or harbor through the water body channel during falling tide, the harbor (bay) penetrating flow is formed, and the key technical problem about the water source water volume of the harbor (bay) penetrating flow is effectively and economically solved. Meanwhile, the method serves as an important measure for ocean resource sustainable development and utilization and ocean environment protection, the water storage water area can be established into the ecologicalwetland environment or created into the hydrophilic space.

Description

technical field [0001] The invention relates to the field of port waterway engineering, in particular to a method for creating an ecological wetland to promote water body exchange in an encircling harbor basin or harbor. Background technique [0002] In the construction of coastal ports, especially in the coastal port construction with shallow water and gentle slopes and active sediment movement, in order to ensure good mooring conditions in the harbor basin or harbor and to prevent the inflow of sediment, an encircling port is adopted. The pool or harbor has become the mainstream form. The encircling harbor basin or harbor has the advantages of high mooring stability, many berths, and long operating coastline. However, with the production activities of the port wharf, pollutants will be discharged into the harbor basin or harbor. In addition, the harbor basin or harbor water area is highly enclosed and the water fluidity is poor. Therefore, most of the surrounding harbor b...

Problems solved by technology

However, in the first type of method, the characteristics of water flow are generally reciprocating movement with tidal fluctuations, and water particles will return to their original positions after a tidal cycle. In addition to water mixing and diffusion effects to surrounding waters, water exchange Its effect of enhancing the water exchange capacity of harbor basins or harbors is sometimes not ideal

In the second type of method, it is often restricted by conditions such as the capacity of the water pump, whether there are suitable diversion channels in the surrounding area, whether the wave and sediment movement around the port area are active, and usually cannot form a sufficient cross-harbor (bay) flow. Difficult to obtain better water exchange effect
