class imod.flow.StorageCoefficient(storage_coefficient)[source]#

Storage coefficient [-]. Be careful, this is not the same as the specific storage.

From wikipedia (

Storativity or the storage coefficient is the volume of water released from storage per unit decline in hydraulic head in the aquifer, per unit area of the aquifer. Storativity is a dimensionless quantity, and is always greater than 0.

Under confined conditions:

S = Ss * b, where S is the storage coefficient, Ss the specific storage, and b the aquifer thickness.

Under unconfined conditions:

S = Sy, where Sy is the specific yield


storage_coefficient (float or xr.DataArray) – Storage coefficient, dims = (“layer”, “y”, “x”).
