5Preface
The current study was scientifically enabled by previous investigations on bank filtration in
general, and in particular on the current test site carried out by the Working Group
Hydrogeology, FU Berlin, and long term data records provided for groundwater and technical
operation by BWB (Berliner Wasser Betriebe), for ground- and surface water by SENSUT
(Senatsverwaltung für Stadtentwicklung und Umweltschutz).
Large parts of the present work have been carried out with inverse modelling. Manual
calibration was not necessary any more. It facilitated the hypothesis testing. It was annoying
that often results were bad or even no convergent solution could be obtained, though fair
manual calibration was possible. In many of these cases the model parameterisation was ill
posed, i.e. deficiencies in the physical meaning of the incorporated processes existed. This
points out a rarely discussed advantage of parameter estimation: The mentally unbiased
consideration of the data on the base of processes included in the model. In this context the
term “objective function” has a much deeper meaning than the mathematical process of its
calculation, i.e. usually the sum of the squared residuals.
In the present work inverse modelling was the only way to distinguish a well posed
conceptual model (the model represents the important system processes) from ill posed
problems, (the parameters are just used in a non physical way to obtain a good curve fit).
Ironically, many modellers believe just the opposite.
This potential of inverse modelling, to respect all data in an unbiased way, becomes the
more important the more data are available. Often, much effort is put on the discussion why
parts of the expensively collected and valuable data only partly provide a consistent picture
with respect to the numerical model. The more data are available, the more difficult it is to find
a consistent view and model concept. In this context the usual suspect of spatial heterogeneity
is often used as a bulldozer in discussion. The potential benefit of inverse modelling, especially
in problems with high amounts of available data, is still underestimated. It is not just a pathway
to fit model curves, but enhances our ability to reject hypotheses, which Karl Popper identified
as the essential way of progress in science.
6Abstract
Several kinds of managed aquifer recharge techniques provide very good purification of
surface water since more than 100 years. In order to maintain a reliable supply of clean water,
they are becoming increasingly popular all over the world.
These methods require low technical effort. At Aquifer Storage and Recovery and ponded
infiltration the recharged amounts are technically controlled. The infiltration water has to be
pumped and often pretreated. At bank filtration this is dispensable, the approach, of using
existing surface water bodies is even more consequent. Exemplarily, at a test site at Lake
Tegel, Berlin, Germany, the hydraulic processes are modelled.
By means of 3D long term regional and transient hydraulic modelling it was detected that
the existing approaches for determining the leakance induce large errors in the water balance
and describe the infiltration zone insufficiently. The le
