Evaluation of the groundwater yield of Berlin water works using regional numerical groundwater flow models

摘要

Using available observed and digital data from the hydrogeological systems within the Berlin region, two regional numerical groundwater flow models were developed using a common methodology. These models encompass for the first time an entire area of about 1,300 km(2) of the groundwater flow system within the common sub-surface catchment area of the Berlin water works. The hydrogeological model and the model aquifers were developed using a unique approach from the available hydrogeological maps and sections of the Geological surveys from Berlin and Brandenburg. The numerical models were calibrated using equipotentials of the pumped aquifer for representative conditions of groundwater extraction as well as using hydraulic information. The models were applied to predict the groundwater yield of eleven water works for the Berlin government water agency.
