摘要：

An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger and a method of obtaining the unsaturated conductivity in a single experiment. The solution is verified experimentally through comparison with measurements of matric potential and moisture content using high-speed tensiometers.
