Corrigenda - A collection system for measuring runoff and soil erosion with a mobile rainfall simulator on sealed and stony red earth soils

Abstract

A collection system was developed for use with a Grierson and Oades rainfall simulator. The collection system enabled measurements of runoff and soil erosion to be made on massive red earth soils with severe seals (or crusts) and stones at their surface. In our design, the collection flume was separated from the other three sides of the plot frame. This allowed the collection flume to be initially inserted with minimum disturbance to the soil hydraulic properties and then connected to the other three sides of the plot frame. Runoff data obtained with this collection system, from a stony, sealed, surface soil, are presented.
