Investigation on the Regulation Techniques for TongGuTan Shoal of Yangtze River

Abstract:

TongGuTan shoal is typical pebble shoals of branching reach with bend in upper course of Yangtze river. Based on 2D numerical model and physical model tests, the features of flow and sediment movement, obstructing-navigation mechanism be studied. In order to achieve permanent improvement of navigation condition, it is suggested to excavate straight channel for navigation. The new structure such as bags-filled-stones dam body, irregular concrete block have achieved the good effects. It provides a good example of dredging construction in flood season to the similar shoal.
