A Rainfall Simulator for the in situ Study of Superficial Runoff and Soil Erosion
A rainfall simulator is an important tool for the study of runoff generation and soil loss because it can be used either under laboratory conditions, or in disturbed or natural soil. The objective of this study was to describe the design and operation of a rainfall simulator to evaluate soil loss in...
