Abstract
Prediction of the infiltration of water into field soils requires knowledge of the field-saturated hydraulic conductivity and a second parameter, such as the matric flux potential (corresponding to field saturation), or the Green and Ampt wetting-front pressure head, or the alpha parameter. Analytical solutions of 1-D infiltration under both constant and falling-head conditions are reviewed and several new solutions are developed based on the Green and Ampt assumptions. A laboratory experiment using the falling head technique is analyzed using several approximate analytical solutions.
