Description
  • Unsaturated and saturated soil hydraulic properties were determined and compared for three sandy soils at adjacent field sites. Drying soil -water retention curves were measured on soil specimens using a pressure plate apparatus. Saturated hydraulic conductivities (Ks) were measured with a Guelph permeatmeter and falling head tests. Parameter optimization was used to simultanously estimate thedrying and wetting soil-water retention and hydraulic conductviity curves from cone permeameter and multistep inflow/outflow data. Ks values from all test methods were within an order of magnitude of each other at each site and, as expected, trended with bulk density. The Quelph permeameter generally yielded the highest Ks values. The soil-water retention curves were similar in shape, except for the cone permeameter curves, which had steeper slopes due to rapid flow of water into the soil. Relative hydraulic conductivity curves wee similar in character to the soil-water retention curves. Each method provided
