|description=If an upper threshold is set, water will only flow out of the model through this [[Inlet (Water Overlay)|inlet]] until the water level at the point of this inlet is equal to or less than the threshold. If the threshold is not set, the amount of water flowing out is not limited in this fashion.
|description=The surface area of the external water body behind the breach. The larger the external water body, the more water can flow from it (or into it), and the smaller the effect of the inflow or outflow of water on the external water level.

==Notes==
==Notes==
* The [[Inlet q (Water Overlay)|INLET_Q]] should be 0 or negative. Otherwise, the inlet is not configured to let water flow out.
* When a [[Breach_input_area_(Water Overlay)|breach input area]] is defined, an external water body will not be created. Subsequently, the [[External_surface_level_(Water_Overlay)|EXTERNAL_SURFACE_LEVEL]], [[External_water_level_(Water_Overlay)|EXTERNAL_WATER_LEVEL]] and [[External_area_(Water_Overlay)|EXTERNAL_AREA]] attributes will be ignored.
