An outdoor experimental watershed was built and consisted of a conic section with 120 deg interior angle, a radius of 110 ft, and a uniform slope of 5%. The watershed surface was stabilized by covering with a sheet of butyl rubber. Rainfall is simulated by overlapping sets of patterns from 164 sprinkler heads set at 10 ft above the watershed surface. The simulated rainfall was uniformly distributed in time and space; but many variations in distribution are possible for future experiments. Runoff is measured by a 1.5-ft H-flume equipped with a modified FW-1 water stage recorder. (Author)
