摘要

The purpose of this report is to describe the simulation of ground-water flow inthe Coastal Plain of North Carolina for conditions prior to and after development of ground water. A finite-difference ground-water flow model was applied to 10 aquifers and intervening confining units, each of which covers all or part of the State's 25,000-sq mi Coastal Plain. Discussions include modeling procedures and boundary conditions, calibration, sensitivity analysis, steady state for prepumping conditions, and transient simulations for 1900-80 conditions. Results of the simulations are discussed with respect to changes in ground-water flow as shown by changes in the water budget, potentiometric surface of each aquifer, and direction of ground-water flow vertically through the confining units. Results are also presented for a simulation of the year 2000 using an assumed constant increase in pumping of 3 percent per year from 1980 to 2000 at all 1980 pumping locations.
