EVALUATION OF AN INDUCED INFILTRATION MODEL AS APPLIED TO GLACIAL AQUIFER SYSTEMS

摘要: : Numerical models were used to examine the limitations of assumptions in an analytical induced infiltration model. The tested included negligible streambed effects, areal recharge, two-dimensional ground water flow, fully penetrating rivers and wells, constant surface stage. For situations that deviate from underlying assumptions, model becomes a less reliable predictor infiltration. numerical experiments show effects cannot be neglected if conductivity is more than one order magnitude lower aquifer hydraulic conductivity. Areal recharge basin receives 5 in/yr recharge. Three-dimensional flow due well partial penetration ratio horizontal vertical (Kh/Ku) greater 10. Surface elevation fluctuations can significantly influence rate, depending on degree gradient.
