基于可控潮汐通道技术的水交换影响研究
Study on the influence of water exchange based on controlled tidal channel technology
摘要
Abstract
The tidal channel plays a crucial role in facilitating efficient water exchange between a bay and the open sea.Controllable tidal channel technology encompasses techniques used to modify tidal dynamics and regulate wa-ter exchange within these channels.In recent years,the environmental quality of bay waters has been steadily de-clining,and there is ongoing debate over the most effective strategies for restoration.Using the semi-enclosed Zhelin Bay as a case study,this research employs the finite element model TELEMAC to propose a novel approach that combines sluice gate control with channel dredging.The study evaluates the impact of this restoration method on the bay's water environment,focusing on tidal dynamics and water exchange processes.The results show that under sluice-controlled conditions,the water exchange rate in the target area increases by 10%-20%,and the half-exchange period is nearly halved,with at least 60%of the water in various sections of the bay being exchanged within 20 days.When channel dredging is combined with sluice control,the water exchange rate improves further,with 70%of the water exchanged over the same period.This combined approach of sluice gate control and channel dredging significantly enhances the water environment within the bay,providing valuable insights and potential guidance for future bay water environment restoration projects.关键词
