Abstract
MODFLOW was used as modeling tool to predict salt movement under three different types of feedlot waste storage ponds: a typical shallow holding pond with a clay liner, a deep unlined pit lagoon, and a shallow evaporation pond with a compacted clay liner. We found that the measured hydraulic parameters and the layer characterization of the underlying strata was not always an exact science. Nonetheless, once the model was calibrated and refined, the outcome appeared realistic.
