Hydro-Economic Modeling of Dynamic Water Abstraction Charges for the Middle Elbe River

Table 1_Low-flow-induced dynamization of river abstraction charges presents simulated abstraction costs and failure day risks from a hydro-economic modeling study. The model combines hydrodynamic river modeling with an abstraction cost model, using hydrological and economic inputs. The approach was tested using discharges of the middle Elbe River between 1990 and 2022.

Use Cases

• Simulating cost differences between dynamic and fixed abstraction charges based on flow-dependent charge rates.
• Estimating failure day risk for meeting minimum flow rates based on simulated hydrological conditions.
• Analyzing hydro-economic interactions for sustainable water management strategies based on the model's scenario outputs.
• Evaluating the economic implications of low-flow events on water abstraction based on linked discharge and cost data.

Strengths

• Model tested with a specific 32-year time series (1990-2022) for the middle Elbe River.
• Provides concrete simulated cost differences (up to 14-17 percent) and an example of additional annual costs (~EUR 200,000).
• Calculates a specific failure day risk (up to 162 days in 2018) for meeting minimum flow rates.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The model does not explicitly represent behavioral responses, limiting interpretation to cost signals.
