Time-Dependent Linearized Infiltration. I. Point Sources1
- A. W. Warrick2
Water flow from a point source is analyzed using a linearized form of the moisture flow equation. Time-dependence is assumed with the results simplifying to those of previous investigators for steady-state conditions. Discrete time-distributed inputs such as might occur for trickle or high frequency irrigation is amenable to the solution. Numerical simulations include (i) the advance of a wetting front during infiltration, (ii) moisture variation resulting from a cyclic input as during irrigation, and (iii) the matric flux potential field for a two-source problem.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
