The volume ratio of large to small particles controls intact sand hydraulic properties. Simple model explained sand saturated hydraulic conductivity within a factor of two. The new concept was also related to effective porosity and water retention points. Soil mineral particles larger than 0.1 mm and organic matter need to be considered.
