Name Prequel Underlying data Unit Range No data Description
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 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.
