* Distance behind the [[Breach (Water Overlay)|breach]] for placing a more stable water level measurement, used in the [[Breach_growth_formula_(Water_Overlay)|Verheij–van der Knaap growth formula]].
* This distance is only taken into account when not using a manual defined [[Breach level area (Water Overlay)|Breach level area]].
* In order to place the measurement the breach area must have a [[Breach_angle_(Water_Overlay)|BREACH_ANGLE]].
* In order to place the measurement the breach area must also have a [[Breach_angle_(Water_Overlay)|BREACH_ANGLE]]. Together they determine the location at which the point of measurement is placed.
* Only when the area behind the breach is lower then the breach level itself the measurement point can be placed. This prevents invalid measurements behind e.g. buildings.
* The downstream water level of the breach is used in the [[Breach_growth_formula_(Water_Overlay)|Verheij–van der Knaap growth formula]].
* Only when the area behind the breach is lower then the breach level itself the measurement point can be placed. This prevents invalid measurement points, for example when it is placed on top of a [[building]].

Breach measurement distance m width can be configured in Breach Growth step of a Flooding Overlay wizard.
Icon Attribute Unit Range Description Default value
Waterwizard icon breach measurement distance m.png BREACH_MEASUREMENT_DISTANCE_M m Distance from the breach area to the automatically placed measurement point for the downstream water level of the breach, in the direction of the breach. 100

Notes

  • This distance is only taken into account when not using a manual defined Breach level area.
  • In order to place the measurement the breach area must also have a BREACH_ANGLE. Together they determine the location at which the point of measurement is placed.
  • The downstream water level of the breach is used in the Verheij–van der Knaap growth formula.
  • Only when the area behind the breach is lower then the breach level itself the measurement point can be placed. This prevents invalid measurement points, for example when it is placed on top of a building.
