Procedures and computer programs for telescopic mesh refinement using MODFLOW
Stanley A. Leake, David V. Claar
1999, Open-File Report 99-238
Ground-water models are commonly used to evaluate flow systems in areas that are small relative to entire aquifer systems. In many of these analyses, simulation of the entire flow system is not desirable or will not allow sufficient detail in the area of interest. The procedure of telescopic mesh refinement allows use of...
