Title: Predicting contaminant migration in karst aquifers

Time-of-travel transport estimation is employed to predict contaminant migration in karst aquifers. Estimation of time-of-travel transport is conditioned on the set of hydraulic-flow that occur within karst conduits. These parameters are applied to surface-water models to reflect time-of-travel flow and geometries are determined empirically through quantitative ground-water tracing studies. Quantitative ground-water tracing studies are based on a comprehensive tracer budget and numerical analysis of the tracer recovery curves for time-of-travel parameters that include mean residence time, mean flow velocity, longitudinal dispersivity, karst conduit volume, cross-sectional area, diameter, and hydraulic depth for use in surface-water models.
