Notes

• To attach a breach input area to a breach using the configuration wizard, ensure that the desired input area does not have a BREACH_HEIGHT attribute but does have a BREACH_INPUT_AREA attribute (set to -1, for example). That area is then selectable as an input area in the configuration wizard, in the step for breaches areas.
• The breach references the breach input area by filling in the ID of the breach input area for the BREACH_INPUT_AREA attribute in the breach area.
• When a Breach input area is defined, an external water body will not be created. Subsequently, the EXTERNAL_SURFACE_LEVEL, EXTERNAL_WATER_LEVEL and EXTERNAL_AREA attributes will be ignored.
