Breach measurement distance m width can be configured in Breach Growth step of a Flooding Overlay wizard.

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.
