Abstract

This paper presents information from and experience with a test developed by the Soil Conservation Service (SCS) to identify dispersive clay soil. Background information on erosion and piping problems, which led to the development of the test, are reviewed. Comparisons of the SCS dispersion test with field performance and pinhole test data are made.
