This attribute can be defined as [[time sequence (Water Overlay)|values over time]], using an array of values defining {{time sequence interpolated}}. This allows users to more dynamically define the height used to allow or deny water flowing across.

Icon Key Unit Range Description Default value
Waterwizard icon weir height.png WEIR_HEIGHT m + datum -10000 to 10000 The height of the weir. Water can flow past the weir when the water level exceeds the weir's height. n/a

This attribute can be defined as values over time, using an array of values defining interpolation-time. This allows users to more dynamically define the height used to allow or deny water flowing across.

Notes

  • When using a dynamic WEIR_HEIGHT, a maximum of 10.000 values (5.000 pairs) can be defined.
  • When using a target upstream water level, the weir height can adjust automatically during simulation. This behavior can also be configured in combination with a dynamic weir height, but can lead to unexpected behavior. Instead for weirs with a target water level, define the weir height as a single start value.
