This paper studied and analyzed the effects of water depth of the channel on the coefficient of roughness. The author puts forward that the channels can appropriately incre- ase the coefficient of roughness of canal botom to improve canal water level to ensure the high irrigation. This paper ch- ose the water measuring point of Pang canal of Huinong canal and made its coefficient of roughness, analyzing the relation- ship between changes of water depth and the coefficient of roughness, and putting forward related suggestions.
