Abstract/Contents: | Discusses modifications to the Rawls et al. saturated hydraulic conductivity, Ks model. States that "Ks is an essential parameter for predicting transport processes through soils." Also states that the model proposed by Rawls et al. "uses effective porosity (defined as air-filled porosity at a matric potential of -33 kPa) modified by a power representing a pore distribution index (defined as the change in porosity between -33 kPa and -1,500 kPa) and by an empirical linear constant." States that the hypothesis proposed by the authors is "the prediction of Ks can be improved by using information of water retention at relatively low matric potentials (indicative of macroscopy)." Describes the conditions of the experiment and lists the modifications made to the Rawls et al. model including "1) defining a new effective porosity (as air-filled porosity at the inflection point) and power index (change is porosity between saturation and the infection point), and 2) expressing the linear constant as a function of the pore diameter at the inflection point and of the power index." Results indicate that "with site specific data the model has the potential to be used in investigations at the field scale." |
