Project description
Integrating geophysics, geology, and hydrology for improved groundwater and environmental management
In this project we will create tools for the direct and automatic integration of spatially dense geophysical and sparse geological data to construct hydrological models for knowledge-based groundwater resource management. This includes to:
- Develop automatic methodologies for transforming spatially sampled geophysical data, using geological and hydrogeological data, to the framework of a hydrological model.
- Use geostatistical methods to describe the correlation between the geophysical data and lithological/hydrological data and to assess the uncertainties from the automatization.
- Demonstrate the benefits of spatially distributed geophysical data for informing and updating groundwater models in terms of their increased predictive power.
We anticipate the results will have a significant scientific and societal impact given that the issues are of high interest in many research groups world-wide. The individual elements will bring substantial insight into integration - particularly automatized integration - of large geophysical datasets into groundwater models that today remains an unresolved conceptual and technical challenge. The outcome will be of high value to Danish end-users (municipalities, regions, consultants) as well as a valuable export article in the form of superior expertise in the industry and actual computer programs.
The project is founded by The Danish Council for Strategic Research
Work packages
The HyGEM project is divided into six Work Packages (WP), five of these being technical WPs and one dealing with dissemination and co-ordination.
In WP1 we will supplement existing and collect new hydrological and geophysical data. In WP2 the collected geophysical data are used as input for a direct geophysical voxel inversion. In WP3 the collected data will supply valuable information to improve the descriptions of the statistical links between geophysical parameters and lithological/hydrological parameters. WP4 will try to directly couple EM data with the groundbased MRS data in the context of hydrological parameters, and finally in WP5 the combined set of collected field data will help designing a test-bench environment analyzing the importance of the different data.
