Última Determination of hydraulic properties of a tropical soil of Hawaii using column experiments and inverse modeling Rev. Bras. Ciênc. Solo Sobotkova,Martina; Snehota,Michal; Dohnal,Michal; Ray,Chittaranjan. A method for determining soil hydraulic properties of a weathered tropical soil (Oxisol) using a medium-sized column with undisturbed soil is presented. The method was used to determine fitting parameters of the water retention curve and hydraulic conductivity functions of a soil column in support of a pesticide leaching study. The soil column was extracted from a continuously-used research plot in Central Oahu (Hawaii, USA) and its internal structure was examined by computed tomography. The experiment was based on tension infiltration into the soil column with free outflow at the lower end. Water flow through the soil core was mathematically modeled using a computer code that numerically solves the one-dimensional Richards equation. Measured soil...
