	EXTERNAL_WATER_LEVEL	m + datum	-10000 to 10000	The water level of the external water body behind the breach. The initial level the water level is set to.	0

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.
The Object datum output b can be used to verify the external water level at each recorded timeframe.
The Object datum output a can be used to verify the water level inside the project area, at each recorded timeframe .
