Impact of Artificial Recharge on Groundwater Quality of Gypsum Aquifer in Harmon County, Oklahoma

摘要

The Strongly Implicit Procedure (SIP) is used to solve the groundwater flow equation, replacing the Alternating Direction Implicit Procedure (ADIP) in the solute transport model (1978, 1979), developed by the U.S. Geological Survey. The SIP Model was then coupled with the dispersion equation solved by the Method of Characteristics (MOC). The comparisons of the SIP-MOC Model against the ADIP-MOC Model indicate that the convergence rate in the flow portion of the problem is significantly improved, saving computer time and the user's computer cost. The SIP Model handles problems which cannot be conveniently solved by the ADIP Model.
