The minimum input data requirements for GWSDAT to run correctly are as follows: For plotting of groundwater flow direction arrows:
- No solute concentration data required
- Minimum 3 well locations in coordinate table
- Minimum 1 measurement of groundwater elevation at each of these 3 wells within the user- selected model output interval
For plotting of groundwater elevation contours:
- No solute concentration data required
- Minimum 4 well locations in coordinate table
- Minimum 1 measurement of groundwater elevation at each of these 4 well locations within the user- selected model output interval
For plotting of solute concentration trends at individual wells:
- Minimum one solute: No groundwater elevation data required
- Minimum 1 well location in coordinate table
- Minimum 1 measurement of groundwater solute concentration at this well location
For fitting of valid spatiotemporal model and plotting of solute concentration contours:
- Minimum one solute: No groundwater elevation data required
- Minimum 3 well locations in coordinate table
- Minimum 2 concentration, time data points for each of these 3 well coordinates
