STATISTICAL EVALUATION OF RAINFALL-SIMULATOR AND EROSION TESTING PROCEDURE

Much money, time and work are expended each year in evaluating new erosion products. Test locations in the field are now hard to find; therefore, a better method of first checking these products had to be found. A tentative laboratory test procedure had been developed by which these products could be evaluated. A rainfall-simulator had been designed and operated using this test procedure; however, complete testing for statistical purposes had not been accomplished. The specific aims of the study were: (1) to supply documentation of statistical repeatability of the rainfall-simulator and the soil-loss data using the test procedure, (2) to reevaluate the design and operation of the rainfall-simulator, and (3) to reevaluate the test procedure. These aims were carried out in a series of repetitive tests.
