Tidal Current Sediment Modeling Study for Hanjiang River Mouth Regulation Planning Scheme

The Hanjiang river mouth regulation guideline scheme and the shoal development scheme have been studied based on the Hanjiang river mouth physical model.The experiment shows three obvious changes:the extension of the river mouth and the coastline has brought minor influence to the flood control situation in the upstream;the sand accumulation in the Xinjin river mouth will change into the mouth sand bar inside the mouth;the sediment volume will increase with the mouth extension in the external channel of shan tou Harbor.
