Attribute: EFLA, [m³/element/TU] (element-wise)

In the transient input file, the EFLA data type is used to change the areal seepage values assigned with FLAE in the model file, or to set the values for element recharge/removal for the first time step (corresponds to data type FLAE from the model file without '*' in column 16).

Attribute: FLAE, [m³/m²/TU] (element-wise)

In the transient input file, the FLAE data type is used to change the areal seepage values assigned in the mesh file, or to set the groundwater recharge rates for the first time step (corresponds to data type FLAE from the model file with ''*" in column 16).

The time unit refers to the specified time unit in the transient input file. The difference between EFLA and FLAE lies in the unit of the input.

Attribute: GW-N, [m³/m²/year] (element-wise)

In the transient input file, the GW-N data type is used to change the values entered with GW-N in the mesh file, or to set values for the recharge rates for the first time step. For transient calculations, it is important to ensure that a standardised attribute is set for the groundwater recharge in the model file and in the transient file, i.e. either FLAE or GW-N. If both attributes are used, they are regarded as different data types, and the combined/summed rate is added to the element.
