Dear Peter,

we have to define in FeFlow the dimensionsless storativity S [-] which is defined as the depth integrated specific storativity SS, which has usually the unit [1/m].

What was the asumption not to define the specific storativity SS to the groundwater model ?

My question is therefore:
What must we assign to the Storativity:

The specific storativity multiplicated with the total depth of the groundwater body S = SS * M or

the specific storativity multiplicated SS with the depth of each layer representing the aquifer, because we assign the storativity for each model layer ?

Best regards Tubaheni

In my experience with FEFLOW, I always used S as the specific storativity multiplicated with the TOTAL depth of the aquifer, and not the SINGLE layer depth.

The dimensionless value for 'Storativity' refers to specific yield. Storage compressibility in the unit 1/m defines the storage per meter head change. Both are not related to the aquifer or layer thickness.
