Numerical simulations of groundwater flow and solute transport in the Lake 233 aquifer

摘要

A three-dimensional numerical flow model of the Lake 233 aquifer underlying the site of the proposed Intrusion Resistant Underground Structure (IRUS) for low level waste disposal is developed. A reference hydraulic conductivity distribution incorporating the key stratigraphic units and field estimates of recharge from Lake 233 are used as model input. The model was calibrated against the measured hydraulic head distribution, the flowpath of a historic (sup 90)Sr plume in the aquifer and measured groundwater velocities.
