Fig. 4. Measured and modeled K() for a Walla Walla silt loam near Pendleton, OR: Measured-internal drainage (ID) is from the internal drainage method; Measured-MKV is from the Modified Klaij and Vachaud; Modeled-1 is from the Mualem-van Genuchten model (MVG), with parameters estimated by the Rosetta model, using soil texture data as inputs; and Modeled-2 is also from the MVG, but with parameters obtained from field-measured water release curve (WRC1) and saturated hydraulic conductivity (K_sat).
