When working with the full groundwater model of the Water Overlay, underground seepage may present a significant factor in the underground water balance. However, especially over longer times, the effects of external seepage can vary. For these situations, it is possible to introduce a time-dependant variation to ground bottom pressure.
For seepage to be functional, the following should be prepared beforehand:
- The Bottom pressure and Bottom resistance overlays based on GeoTIFFs.
- A csv with a start-time time sequence for the seepage fluctuation.
Editor → Current Situation (Ribbon tab) → Overlays (Ribbon bar) → Water Overlay (Left panel) → Configuration Wizard (Right panel) → Seepage
How to configure variable seepage:
- Open the Water Overlay Wizard, and proceed to the seepage step.
- Opt to configure seepage.
- For the pressure GeoTIFF, import your GeoTIFF Overlay with seepage pressure values.
- Ensure the uploaded GeoTIFF is selected in the dropdown.
- For the resistance GeoTIFF, import your GeoTIFF Overlay with seepage resistance values.
- Ensure the uploaded GeoTIFF is selected in the dropdown.
- Set the seepage factor to "dynamic", and opt to select a csv.
- Import the prepared csv.
- Close the import window.
- Close the configuration wizard, and recalculate the Overlay.
