THE DOWNCUTTING OF BEIJIANG RIVERS BED AND ITS EFFECT ON IRRIGATING ENVIRONMENT
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 sever 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 of water treatment. These problems constitute a great threat to the sustainable development of Beijiang regional economy. In this paper, first the degree of Beijiang Rivers bed downcutting is expatiated, and then its bad effect on irrigating environment is analyzed deeply, finally corresponding harness measures are put forward.
