AnAqSim Instructional Series: Exercise Set 7

Hydraulic Features - Areal

AnAqSim provides numerous methods for including areal hydraulic features in an aquifer model. These features may be part of the aquifer (e.g. an area at the aquifer’s surface where water is added by recharge or lost to evapotranspiration (ET)) or they may represent a surface water feature that is hydraulically connected to the aquifer (e.g. a wetland, pond or lagoon). Recharge or ET may be easily applied as a domain area in which the top flux is set at a different value than the surrounding regional aquifer (greater for recharge; lesser for ET). Discharge from the aquifer to a pond or wetland area can be represented by an array of spatially-variable area sinks (SVAS) radial basis points with head values set at the water level in the pond or wetland. In addition, groundwater flow out of the aquifer, into and through a shallow pond, and then back into the aquifer can be represented using a small domain set to a very high hydraulic conductivity value (which represents no resistance to flow).

Topics covered in the Set 7 Exercise Package include:

  • Discharge to a pond / wetland using a head-dependent flux domain
  • Areal recharge to the aquifer (e.g. spray irrigation) using increased specified recharge
  • Pond / lagoon recharge to the aquifer using increased specified recharge
  • Pond or lagoon defined using a domain with specified head boundary
  • Flow through pond created using a high hydraulic conductivity domain

The Set 7 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!
