Table for lower UZ boundary¶

Groundwater table for lower UZ boundary
Conditions	If Unsaturated Flow selected in the Simulation Specification dialogue without selecting Saturated Flow, OR If the Unsaturated Flow is selected and the Linear Reservoir Method for groundwater is selected.
dialogue Type	Stationary Real Data
EUM Data Units	Elevation or Height above ground

The groundwater table must be explicitly defined if unsaturated flow is simulated without explicitly simulating groundwater flow. The specified groundwater table is used as the lower boundary condition for the unsaturated model.

If the Linear Reservoir Method is used for the groundwater simulation, the water table is not calculated, thus requiring the water table to be explicitly defined.

However, the specified groundwater table is a static variable. If you need to relate your unsaturated zone model to a dynamic water table, you must include the saturated zone in your model based on the 3D Finite Difference Method.
