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

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

NP3: (Preparation for) sub-surface measurements (Wim, 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

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
