Model Code Name:

ZOOMQ3D is a numerical model which advances the art of model development on two vitally important fronts. It incorporates a mesh refinement procedure which aids the solution of problems related to scale. This is the first of its contributions. The second is that it uses object-oriented techniques as the basis for the program. Whilst this is well-established in the development of general commercial software, it represents a novel approach to groundwater model structure. It is of considerable value in maintaining the code but it is in changing model behaviour that it holds most promise for modellers. Further, the direct correspondence between computer-based objects and real-world features makes the link between numerical and conceptual models very easy to see, even to those with no programming expertise
