Dike Closure Technology in Reclamation Project Under the Complex Hydrological Condition

The construction difficulty of dike closure would be increased when multi-basin rivers are converged on the reclamation project area.Taking Shenglitang north reclamation project in Zhejiang Province as an example,the paper introduced technology and engineering measures dealing with high and low tide grooves and protecting the closure dike,analyzed the impact of construction on the drainage of the upper reaches,presented an optimizing method by forecasting tide process to the dike closure process.
