Optimized water exchange method between open sea and inner lake water system

Abstract

The invention discloses an optimized open sea and enclosed lake water system water exchange method. The optimized open sea and enclosed lake water system water exchange method comprises the followingsteps of setting a water level upper limit value and a water level lower limit value of an enclosed lake water system; arranging at least one water diversion gate or water diversion valve and at leastone emptying gate or drainage valve at the junction of an open sea water system and the enclosed lake water system; prestoring diachronic tide level data, the water level upper limit value and the water level lower limit value in a database of a gate control system, analyzing and controlling to open and close the at least one water diversion gate or water diversion valve and the at least one emptying gate or drainage valve through the control system to enable sea water of open sea to flow into the enclosed lake water system through the at least one water diversion gate or water diversion valve to form a unidirectional flow control flow state, flow to the at least one emptying gate or drainage valve and then be discharged to the open sea. Through the optimized open sea and enclosed lake water system water exchange method, the exchange efficiency of water of the enclosed lake water system communicating with the open sea and water of the open sea can be substantially improved, and the water level of an enclosed lake is controlled to change within a certain range without radical change.

Description

technical field

[0001] The invention relates to the technical field of water body exchange test research, in particular to an optimized method for water body exchange between an open sea and an inner lake water system. Background technique

[0002] In order to develop tourism resources, according to the concept of lagoons, the inner lake water system connected to the outer sea is designed in coastal tourist areas or artificial islands on the sea, which strengthens the landscape characteristics of tourist areas and emphasizes the concept of environmental protection. In order to meet the use functions, it is necessary to ensure the water quality of the inner lake water system excellent. The water quality of the inner lake is guaranteed by relying on the dynamic changes of rising and falling tides in the outer sea to exchange the water in the outer sea with the water in the inner lake. Water is diverted during high tide in the open sea, and the level of the open sea rises duri...
