| Abstract: | In view of insufficient studying on rainfall test of small watershed model,the paper analyzes some characteristics parameters of simulated rainfall,such as rainfall intensity calibration,raindrop sampling,drop size distribution and rainfall energy by using vectorization software of computer and combining with colored patches,based on modeling experiment.It obtains that raindrop median diameter of each event of rainfall is 1.122 7 ~ 2.139 4 mm and the total kinetic energy of model rainfall is 188.74 ~ 3 980.03 J/mm when rainfall intensity of model is between 0.114 mm/min and 1.33 mm/min under the conditions of different nozzle combination and different head pressure. |
| Keywords: | small watershed model simulated rainfall rainfall characteristic raindrop diameter Loess Plateau |
