The development and validation of the object-oriented quasi three-dimensional regional groundwater model ZOOMQ3D

This report documents the modifications made to the object-oriented regional groundwater model ZOOM2D (The University of Birmingham, 2001). Additional mechanisms are introduced to this model to satisfy the generally-accepted functional requirements of a commonly-applied regional groundwater flow model. The modified model, ZOOMQ3D, is quasi three-dimensional and is validated through comparison with analytical solutions and with instructional problems formulated for MODFLOW (McDonald and Harbaugh, 1988) by Anderson (1993)
