Abstract: Core Ideas 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. The volume ratio concepts seem promising for developing pedotransfer functions. Hydraulic conductivity (Ks) and effective porosity (ϕeff) for saturated water flow are essential hydraulic properties ...
