Analysis of the Impact of Dredging Projects on Some Sections of the Main Stream of Jianjiang River
Through the establishment of hydrological mathematical models and other means,the impact of the dredging project on some sections of the main stream of the Jianjiang River on river hydrodynamics,water ecology and other aspects was analyzed.The research results show that after the dredging of the river,the average elevation and deep water elevation of the river have decreased,the water level of the river has decreased,and the flood carrying capacity of the river has improved.After the dredging is completed,the overall flow pattern of the river has not changed much,and as the flood carrying section of the river has been restored,It is conducive to maintaining the stability of the river;during the construction period and after the river is dredged,the topography will change to a certain extent,and the water flow and river bed substrate near the dredged river bed will change,which will have an impact on the river water ecological environment.
