SOIL ERODIBILITY NOMOGRAPH FOR FARMLAND AND CONSTRUCTION SITES

A NEW SOIL PARTICLE-SIZE PARAMETER WAS FOUND AND USED TO DERIVE A CONVENIENT ERODIBILITY EQUATION THAT IS VALID FOR EXPOSED SUBSOILS AS WELL AS FARMLAND. A SIMPLE NOMOGRAPH PROVIDES QUICK SOLUTIONS TO THE EQUATION. ONLY FIVE SOIL PARAMETERS NEED TO BE KNOWN: PERCENT SILT, PERCENT SAND, ORGANIC MATTER CONTENT, STRUCTURE, AND PERMEABILITY. THE NEW WORKING TOOL OPENS THE DOOR TO SEVERAL NEW CONSIDERATIONS IN SEDIMENT- CONTROL PLANNING. /AUTHOR/
