In the paper we study the evolution process of river channel and talk about the change and tendency of channel patterns by controlling slope and the ration of width to depth, while the initial river is set as the straight channel. During seven experiments the slope was changed from a minimum of 50/00 to a maximum of 180/00. Three types of channel pattern that are braiding, meandering and straight occurred in the experiments reported here.
