BREACH_MEASUREMENT_DISTANCE_M | m | 0 to 10000 | Distance from the breach area to the automatic downstream water level measurement point, in the direction of the breach. | 100 |
Notes
- This distance is only taken into account when not using a manually 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.
- The measurement point is only placed if the calculated location is lower than the breach level, preventing invalid placement (e.g., on top of a building).
