LINKFLOW, a water flow computer model for water table management: Part 2. Model verification

Abstract

A computer simulation model, LINKFLOW, was developed (Havard et al., 1995) to simulate the movement of water during various water table management practices. This article described the validation of the linked saturated-unsaturated water flow model, LINKFLOW. The model was validated against published data on water table elevations during transient drainage. Simulation results were compared with measurements from field experimental plots. Results from the validation indicate a good comparison between simulated and measured values. Coefficients of variation for simulated and measured water table elevations were typically less than 15% for all water table management plots during the growing season. Verification showed that LINKFLOW could simulate the spatial influence of water table movement during various water management systems and account for soil property variation with depth and topography.
