Particle Size Classification

As part of our strategic research we have developed a new particle size classification (PSC) and a new particle size distribution classification (PSDC, frequently referred to as 'texture') with new systems of nomenclature for each. A computer program, in Microsoft Excel 2007/2010 format, is freely available which automatically classifies sediment or soil samples in terms of the percentages of gravel, sand and mud (GSM) or sand, silt and clay (SSC). Full details of the classification scheme are currently in press.
