| Name | Prequel | Underlying data | Unit | Range | No data | Description |
|---|---|---|---|---|---|---|
| Bottom Resistance | BOTTOM_RESISTANCE | Water Prequel | days | 0 to 1000000 | Clamped to range | A grid of values containing the resistance of the lower layer against the seepage. |
Notes
- The unit is: the number of days it would take to equalize 1 meter of the local groundwater table level with the higher region's water head. (days)
- The values in this prequel grid are clamped between 0 and 1000000. No data values are therefore not allowed, but could be clamped to zero when negative leading to the same result.
- This prequel can also have multiple input frames. In this case the values will be updated linear throughout the simulation period. For example 5 input frames over a 10 day simulation period result in a new value every two days.
- Note: Input frames are not linked to the overlay's output timeframes.
