| Abstract: | We present a simple method in two dimensions for the determination of exponential soil-water diffusivity. This determination is made by measuring the wetting front position when water is injected in the soil at different fluxes. The results are exact and represent an improvement over previous techniques both in terms of ease and accuracy.1 |
