Title: "Improving the predictivity of large-scale numerical groundwater models"
Place: Pfaffenwaldring 61, Room U.1.003 (MML), 70569 Stuttgart-Vaihingen
Abstract:
Numerical groundwater models are well-established and widely used tools for decision-making in groundwater management. An example is the groundwater model of the Donauried, a major groundwater resource in southwestern Germany. To support sustainable management of the Donauried, the main objective of this work is to systematically improve the predictive capability of this model. First, an extended approach for estimating the response time of groundwater systems is presented to evaluate the influence of transient initial conditions on model output. Next, a new method is introduced to ensure that the model output is not significantly biased by transient initial conditions. The planned procedure for estimating model parameters is then described. Finally, the intended strategy for applying data assimilation to the model is outlined.
The results of the completed tasks are presented and discussed. Open questions and methodological decisions for the planned work are highlighted. Throughout, the focus is on contributions to improving the predictive capability of the large-scale numerical groundwater model of the Donauried.
