STUDY ON THE WIND-WAVE VARIATION IN THE NORTHERN PART OF GEHU LAKE UNDER ARTIFICIAL TERRAIN REMODELING PROJECT
Wind-wave is one important hydrodynamic factor that affect the physical habitat environment of shallow lakes.A wind wave model was established based on the measured wind wave data in Gehu Lake between Wujin and Yixing,Jiangsu,South China.The verification results indicate that the model can better simulate the changes of wind waves as a function of wind field,based on which the changes of wind-wave condition in the northern part of Gehu Lake after the implementation of the artificial terrain remodeling project were analyzed.Results show a certain degree of attenuation in the wind-wave intensity and the disturbance intensity under the prevailing winds in different seasons,which was conducive to the improvement of water transparency and underwater lighting conditions.The attenuation of wind-wave intensity favored the water area with good wind-wave conditions for better growth and quick development of aquatic plant.The implementation of artificial terrain remodeling project had improved the physical habitat environment of the northern part of Gehu Lake,providing a good support to the restoration of aquatic vegetation,and a reference for the implementation of terrain reshaping projects in other shallow lakes.
