Subsurface Exploration and Analysis for Infrastructure Development
Explore the detailed plan for geology, hydrogeology, geophysics, and geotechnics to analyze subsurface conditions, minimize risks, and optimize infrastructure development. Team efforts and data exchanges play a crucial role in meeting common objectives and ensuring project success. Various deliverables and timelines are set for each aspect of the project to achieve comprehensive results.

SPB WD2 Leonardo Casini (UNISS) Fr d ric Nguyen. (ULi ge) Wim Walk (Nikhef)
WD2 : Geology WP2.1 Structural geology WD1 Physical variables and characterization WP2.2 Hydrogeology WD2 : Geology SPB/SCB WP2.3 Geophysics WD3 Bidbook WP2.4 Geotechnics WD4 Cost timing and risk assessment WD5 Legal and site preservation WD6 Socio-economic and environmental impact
Short overview Target common objectives and timing in terms of the subsurface parameters that will impact the ET sitting, costs and/or operation Coordinate teams effort and promote data/methods exchanges Provides imaging at regional (tunneling) and local scales (caverns) Derive structural model and rock quality model (design TBM) Define groundwater conditions in terms of pressure and flow (prevent issues) Link with WD1 (e.g. impact in terms of vibration propagation) and with WD4 (costs impact as a function or rock quality or water ingress) + others as well
WP2.1 : Structural Geology Chairs : TBD TBD Deliverables : 3D numerical model and maps (EMR : open source GemPy format) Timeline: December 2023 and continuously updated
