Lusatia feasibility study

Lusatia feasibility study

The Lusatia feasibility study pursued two objectives: (1) to examine the possibilities and limitations of water balance modeling in the Spree and Neisse catchment areas, which are heavily influenced by lignite mining, without complex groundwater flow models; and (2) to conduct a benchmark study of the ArcEGMO, Raven and HydPy model kits by means of functional and stress tests. The tests under controlled, synthetic conditions and with real data evaluated the functionality of the models in terms of mathematical correctness, hydrological plausibility and feasibility of technical structures.

This was supplemented by comprehensive analyses of groundwater levels, map bases and state changes after 1990. The results are: modeling of the natural water balance is possible without a flow model, but requires stable groundwater levels. Deviations in the study, particularly with regard to flow rates, can be explained by a lack of information on anthropogenic interventions and operational reservoir management.
