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 contains data collected in a fluvial gravel aquifer at the field site "Kappel-Grafenhausen" in the Upper Rhine Valley, Germany, during different pumping tests (including a step-drawdown pumping test) conducted in a large diameter pumping well with drawdown observations in the pumping and 15 observation wells as well as pumping tests in a tomographic layout.
Abstract (English)
The stratification of sedimentary aquifers introduces spatial variability in hydraulic conductivity, primarily between individual horizontal layers. On larger scales, the vertical heterogeneity enhances hydraulic anisotropy with the horizontal conductivity typically exceeding the vertical one. We collected pumping test data sets for the estimation of the hydraulic anisotropy of a stratified aquifer with numerical modelling. The data sets were collected in a fluvial gravel aquifer at the field site "Kappel-Grafenhausen" in the Upper Rhine Valley, Germany, during different pumping tests conducted in the large diameter pumping well R01 (DN 800 mm). We conducted a step-drawdown pumping test with drawdown observations in the pumping and 15 observation wells as well as pumping tests in a tomographic layout. For latter we sequentially extracted water from pumping well sections screened at different depths and measured the hydraulic response at various multi-level observation wells at different distances and directions from the pumping well. This data set consists of three parts: i) data from a step-drawdown pumping test (pumping from all screen sections), ii) the raw data which contains the transient-state data from 22 pumping tests performed in the three screen sections of the pumping well R01 with different pumping rates, and iii) a processed and reduced data set containing steady-shape pumping test data.
