Abstract

A portable rainfall simulator featuring a rotating disc and nozzle, has been developed for use in field studies of erosion, infiltration, and runoff processes. Variable intensities of simulated rainfall ranging from 15 to 150mm h−1 are produced by choice of appropriate nozzles and slot apertures in the rotating disc. The duration of the simulation can be precisely controlled by a shutter mechanism. The measured uniformity coefficients ranged from 91.2 to 94.3%. The kinetic energy of the simulated rainfall at intensities above 30 mm h−1 was close to that of natural rainfall.
