Heterogeneities

AnAqSim is based on the sub-domain analytic method. This provides AnAqSim with one its key strengths: the ability to easily include heterogeneities (sub-domains or zones) of different types within the overall regional aquifer domain. These zones can be set with different aquifer properties, different recharge rates, etc. Higher hydraulic conductivity zones cause a convergence of regional flow, while lower permeability heterogeneities cause divergence of regional flow as It moves through and around the zone. Rules for digitizing and specifying the order of vertices along boundaries of various types are presented.

Topics covered in the Set 5 Exercise Package include:

• Basic introduction on how to create sub-domain heterogeneities
• Rules for digitizing heterogeneity boundaries of different types
• Embedding high hydraulic conductivity zones in an aquifer model
• Embedding low hydraulic conductivity zones in an aquifer model
• Using pathlines to examine changes in flow patterns for each zone type

The Set 5 Exercise Package contains instructional lessons, any necessary modeling input files, basemaps, etc; and a set of step-by-step completed AnAqSim files that you can load at any point if you want to check one of the exercise steps – everything you need to continue learning groundwater modeling using AnAqSim!
