Calculation of longitudinal dispersion coefficients in the vadose zone using soil water characteristic curves



Calculation of longitudinal dispersion coefficients in the vadose zone using soil water characteristic curves



Proceedings of the NWWA/US EPA Conference on Characterization and Monitoring of the Vadose Unsaturated Zone: 178-202



Values of longitudinal dispersion coefficients are dependent on the water velocity distribution in a porous media. To obtain the water velocity distribution, the entire flow region was partitioned into a number (NK) of flow paths. The flow paths at the higher saturations are assumed to have the largest pore size, while those at the lower saturations are assumed to have the smallest pore size.
