Attribute: EICH [meters above reference datum] (node-wise)

Using EICH, hydraulic head values which are representative of the starting conditions for the model are defined. These values tend to be measured values from monitoring points in reality and are used during calibration for the iterative adjustment of model parameters, and in some cases for the calculation of the initial thicknesses.

The initial potential heads can be used in transient calculations as the starting potential heads for the first time step (t = 0).
