An analytical model was developed to describe the process by which pore water from a saturated porous media is entrained in overland flow. Obtaining a better understanding of this process is critical to the development of reliable simulation models for non-point source pollution. A series of laboratory experiments was performed to test the validity of the model and to provide empirical formulas relating diffusional model parameters to overland flow and porous media parameters.
