Descriptions of Anisotropy and Heterogeneity and Their Effect on Ground-WaterFlow and Areas of Contribution to Public Supply Wells in a Karst Carbonate Aquifer System

摘要

This report describes aquifer anisotropy and heterogeneity in a karst carbonateaquifer, how these heterogeneities affect ground-water flow, and their effect on the size, shape, and orientation of contributing areas to well fields. The specific purposes for the report are to: (1) Describe the anisotropy and heterogeneity typical of karst carbonate aquifer system; (2) Present effects of aquifer anisotropy and heterogeneity on ground-water flow; (3) Show the effects of aquifer anisotropy and heterogeneity on areas of contribution to supply wells; and (4) Compared delineation of protection zones determined using analytical methods and areas of contribution determined using numerical methods.
