TWO-DIMENSIONAL GROUNDWATER MODELING WITH MICROCOMPUTERS
Additional Document Info
Two simple numerical models adopted for microcomputer applications and used to analyze groundwater problems are described. The alternating direction implicit method is an iterative procedure used to model relatively large two-dimensional aquifers on microcomputers. The direct solution model uses a checkerboard numbering pattern of the grid elements to reduce the number of continuity equations and solves the remaining equations simultaneously. The analysis of a water barrier and recovery system for a petroleum products terminal is presented in the paper, and the computation times for both models are compared using IBM, AT&T, and HP microcomputers ASCE.
