| Bottom Pressure | BOTTOM_PRESSURE | Water Prequel | m datum | -1000000 to 1000000 | Clamped to range | A grid of values containing the head of the ground water pressure caused by ground water in higher regions outside the project area. |
Notes
- The values in this prequel grid are clamped between -1000000.0 and 1000000. NO_DATA values are therefore not allowed.
- This prequel can also have multiple input frames. In this case the values will be updated linearly 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.
