I have a model and very few data and I need to input the specific storage. I realise it is the compressibility so, due to lack of data I have to rely on average values in the literature. My problem is, the literature gives values in several distinc units but not in FEFLOW units 1/m. I have a free water body and several mudflats in my model. Can you please give me the link wheere I can find values on FEFLOW units for these ones?
