1 Geological 3D-model of the Basel region - a tool to explore geopotentials Dr. Horst Dresmann Prof. Peter Huggenberger Dr. Janis Epting GeORG technical workshop , Freiburg 1/24

2 Where are useable geopotentials? GeORG technical workshop , Freiburg 2/24

3 We need a tool to handle exploration, rules and planning concepts! GeORG technical workshop , Freiburg 3/24

4 GeORG INTERREG IV A project Geological 3D-model of the Basel Region motivation data management input data modelling current stage 3D-surfaces model size 30 km x 20 km x 6 km (depth) detail (size 4 x 4 km) GeORG technical workshop , Freiburg 4/24

5 Topics with relevance to geopotentials Geothermal energy (shallow and deep) Traffic infrastructure (tunneling) Technical infrastructure Groundwater management Storage of gas (CO2) Earthquake hazard evaluation Quantitative Microzonation Map In cooperation with the Swiss Seismological survey (SED) or GeORG technical workshop , Freiburg 5/24

19 first products: horizon - base unconsolidated rocks (view from S) elevation map masl 800 unconsolidated rocks 200 thickness distribiution thickness 0 unconsolidated rocks GeORG technical workshop , Freiburg 19/24 >25

20 first products: horizon - base unconsolidated rocks vs. new data new borehole data: back in Arc GIS comparison between modelled surface and new borehole data GeORG technical workshop , Freiburg 20/24

21 Summary - A tool is needed to handle the data and knowledge. - The data management and modelling should be flexible: ~ to handle diverse requests ~ in- & export of data ~ adjustable & extendable ~ resolution & scale ~ open for different kinds of data - The influence of new data should be visible. GeORG technical workshop , Freiburg 21/24

22 Outlook - continuation of the 3D-modeling - further development of the data management (e.g. improvement of communication between database, GIS and 3D-modeling) - integration of the urban 3D subsurface (e.g. tunnels, water supply channels, house cellars, sites using thermal energy and more) - studies on the geological evolution of the area (rifting, thrusting, palaeo-geography) GeORG technical workshop , Freiburg 22/24
