The Cause of Beijiang River Water Surface Curves Descent and Evaluation of its Effects on Diversion Environment along the River
In recent years, the Beijiang Rivers bed has been undergoing severe downcutting, which resulted in drop of the rivers water surface curve and caused to the diversion structures and their channels a series of new problems, such as severer scour of banks and hidden troubles in the diversion structures, threatening the dyke safety; reduced diversion volume, silting of channels in the lower reaches, poorer self-cleaning capacity of channels, worsening of water quality and great increase in the expense for water treatment. These problems constitute a great threat to the sustainable development of Beijiang regional economy. This paper describes the bed downcutting of the river, analyzes the bad effect of the bed downcutting on the diversion environment, and presents suggestions on corresponding countermeasures.
