Description
The Hydrogeology group at the Department of Geoscience of the University of Tübingen performs field oriented research at various hydrogeological research site in Southwest Germany. The research focuses on the development of hydrogeological site characterization methods including hydraulic and tracer testing, partly combined with geophysical surveying methods.
This data set includes data from a hydraulic and tracer tracer tomography test acquired at the Hydrogeological Research Site "Lauswiesen".
Abstract (English)
Pumping and tracer tests are site-investigation techniques frequently used to determine hydraulic conductivity. Tomographic test layouts, in which multiple tests with different combinations of injection and observation wells are performed, give a better insight into spatial variability of the hydraulic aquifer properties. While hydraulic tomography has repeatedly been applied in the field, tracer tomography lags behind. We developed an experimental method for solute-tracer tomography using fluorescein as a conservative tracer, and applied it at the Hydrogeological Research Site Lauswiesen in Southern Germany. The hydraulic and tracer tests were performed with a tomographic layout of 4 x 5 observation wells distributed over a 10 x 10 m area. Nested injection-extraction well pairs were generated for repeated tracer injections at different injection intervals. The tests resulted in this data set, which was published in Sánchez-León et al. (2020). The data set is stored in a hdf5-data base that contains the raw data, and the processed drawdown and breakthrough curves of the tomographic hydraulic and tracer tests. It also includes all relevant information about the wells used during the experiments and all necessary metadata.
