摘要：

A simple to understand and easy to implement numerical technique, based on reverse calculation of ground-water flow paths, is applied to delineation of time-related capture zones around water-supply wells. The areal extent of a t-year capture zone in a two-dimensional regional flow domain is approximated by a large set of reverse pathlines all with t-year travel times. The numerical approach is suitable for calculation of time-related capture zones in steady, nonuniform flow with inhomogeneous, anisotropic aquifer conditions. The example applications show the sensitivity of this technique to the influence of multiple wells in a block inhomogeneous flow regime.
