The Estimation Method of Channel Quality

On the basis of the introduction about water saving irrigationthat works as a kind of new irrigation pattern ,the method of anti-seep quality estimation of the conveying water and distributing channel which acts as an important engineering measure of water saving irrigation will be introduced in te paper,that is,by means of unit-length of channel's water utilization-coefficient(ηo)to estimate the quality of channel ,and the calculative method has been explained by the example of an actual project.It can be referred to irrigational workers.
