An Enhanced Flume Testing Procedure for the Study of Rill Erosion

This paper presents the development and verification of an improved and cost-effective flume apparatus and corresponding testing methodology. A rigorous analysis of the flow conditions during testing was considered and an interpretation of test results was carried out following the premises of the W...
