Irrigation and drainage channels play an important role in developing irrigation projects in farmland,and also an active role in controlling water logging and saline-alkaline disasters.In this study,a flume experiment was carried out to analyze the gross and specific stream power of the drainage channels,and two channels in Pingluo County of Ningxia Hui Autonomous Region were separately paved with saline soil and sand.The stability and erosion of these drainage channels were analyzed based on the characteristics of stream power.The results showed that,under the given conditions,the gross stream power of the muddy drainage channel was much lower than that of the sandy one,and it could be quickly reduced to achieve a balance of the channel.The experiment also revealed that the stability of muddy channel was higher than that of the sandy one.Therefore,it is suggested to take muddy channel in developing and improving saline soil in Pingluo County.
