However, prediction of their behavior is often difficult, especially in heterogeneous aquifers because of the lack of information about flow- and transport-governing subsurface structures and parameters. Hence, stochastic approaches have been developed and frequently used. However, extensive modeling studies on sedimentary structures have shown that consideration of hydrogeological subunits and their distribution can be essential for transport modeling. A case study from the intensely investigated Lauswiesen site is used to demonstrate that more accurate predictions are possible with improved knowledge of deterministic structures. Results of this case study using direct-push injection logging (DPIL) provide a more reliable characterization of hydraulic conductivity than sieve and flow meter data.
