Transport von gelösten Stoffen im Grundwasser - Untersuchungen am Testfeld Krauthausen

Hydraulic conductivity estimation from induced polarisation data at the field scale — the Krauthausen case history

“…The site is operated by the Agrosphere, ICG-IV, Forschungszentrum Jülich, Germany. It has been investigated in detail by drillings, grain size analyses, tracer tests and geophysical methods, and the hydrogeological situation is well known Englert et al, 2000). Fig.…”

“…2, filtered within the aquifer (between 1 and 10 m depth), using a flow rate of 80 m 3 /h. It may be considered an average value representative of the entire aquifer (Englert et al, 2000).…”

“…The IP-determined S por values match the BET-determined data quite well for both sets of equations. (Englert et al, 2000). The shaded area denotes the unsaturated zone where the equations are invalid.…”

“…Results from the two profiles crossing b32 and b22 are discussed here. The open square indicates the borehole where a pump test was carried out (afterEnglert et al, 2000).…”

“…Dashed lines: from the Börner model using different values of exponent c. Symbols: from the Slater and Lesmes model. Dash-dotted line: result from a pump test(Englert et al, 2000).…”
