The modeling erode rainfall device by using moni-spray gun to change rain intensity has been made through many times select experiments. More 250 times experiment resultsshowed that the device has an area of 20~~40m2 supplyed for efficient rainfall formed. The reIation between rainfall intensity I and supplying water pressure P is as follows: I=13.017P1.456,r=0.978.The rainfall equality coefficient K≧0.80.The rainfall motive energy E, the size a and the med direction d50% is respectively related to P as follows: E=6.374P0.459,r=0.928,a=0.919P0.259,r=0.909,d50t=0.856P0.258,r=0.880.
