| Boundaries |
Location and type of boundaries for an area to be modelled (topography) |
Boundary types include specified flow, specified head, and head-dependent flow etc. |
| Geological framework |
Geological units and corresponding hydrostratigraphic units and model layers and associated aquifer parameters. Bedrock configuration and aquifer or aquitard characteristics |
Hydrostratigrahic units comprise geological units with similar aquifer properties. a geological formation may be subdivided into aquifer and confining units ( or several layers) |
| Hydrological framework and stresses |
Rate of recharge, extent of recharge area and discharge processes and dominant aquifer flow mechanisms |
Definition of aquifer media type (porous medium and fractured rock), and surface groundwater interaction processes (aquifer characteristics) |
| Human induced factors |
Anthropogenic influence on the system |
Pumping, drainage, etc |
| Groundwater Balance |
