It is assumed that the storage capacity and storage coefficient of the upper ground water storage are lower than the lower ground water storage. It is because the storage in lower zone represents the saturated groundwater aquifer with longer residential times. These values are difficult to acquire as they cannot be directly measured.
Schwarze (1999) provides recession constants and volumes of the lower ground water storage for differernet types of hydrogeological formations (Figure below). The information provided on this publication could be very instrumental in deriving the parameters values of a catchment for users.
A sample parameter file for different geological formations of Thurigian catchment are provided as a example.
After setting up the model file, users may wish to change the values (storage and recession coefficient) and observe their influence on hydrographs. This might provide ideas about the sensitivity of these values in model results.
