“…This finite-difference scheme was a two-step explicit approach named predictor-corrector by Mac Cormack (1969), and was conditionally stable and convergent. The second is its use of NHML to properly approximate the sloping base (Harte 1994). To deal with groundwater flow in an unconfined sloping aquifer, the commonly used three-dimensional finitedifference model MODFLOW (McDonald and Harbaugh 1988) can be a powerful tool if one can adequately handle the characteristics of the sloping base.…”

“…The first is its capability to handle the free water table using the rewetting package (Niswonger et al 2011). The second is its use of NHML to properly approximate the sloping base (Harte 1994). In fact, NHML is capable of dealing with variable sloping angles, making it very useful for studying realistic sloping aquifers over a large spatial scale which may see variable sloping angles at different locations.…”

“…This is different from the truncation error associated with grid size and contains a component proportional to the deviation of the grid from being orthogonal. The errors induced by conforming grids were previously studied by Weiss (1985), Harte (1994), Hoagland and Pollard (2003), and Bower et al (2004). They concluded that the appropriate grid size could be determined a priori for a given problem.…”
