The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these techniques can provide quality data points, they are often limited by sparse data sampling and scale. Therefore estimation of the conductivity model may lack spatial resolution and may not represent the complexity of the true model. Here we present a technique for estimating Ks in an unsaturated medium using infiltration method, level-set method and time-lapse ERT methods.
