13:30 → 13:50 NP1: Analytic understanding of NN (Stefan et al.)¶

Integral understanding of NN modeling
clear definitions, in response of (sometimes confusing) publications of Harms et al.
Analytical calculations for simplified geometry and geology
Deliverable: a paper (living-doc?) describing all aspects of NN modeling

13:50 → 14:10 NP2: Validation of the numerical tools (Stan, Michael et al.)¶

Compare to the analytic calculations
Gradually increasing complexity: layered geology and realistic geometries
Deliverable:
1. (written) comparisons of the various tools
2. understanding of the effect of layered geology and geometry effects

14:10 → 14:30 NP3: (Preparation for) sub-surface measurements (Michael et al.)¶

Merge surface and sub-surface measurements
Attenuation and effect of the motorway on seismic activity underground
Magnetic disturbances - effect of train traffic
Calculations of NN based on measurements
Delivery: assessment of the sub-surface NN level

14:30 → 14:50 NP4: Mitigation (Achim et al.)¶

Generation of ideas and development of tools to mitigate NN
Delivery: assessment of the level of mitigation that can be obtained
