| Zusammenfassung |
Today there is a great consensus that water resource research needs to become
more holistic, integrating perspectives of a large variety of disciplines.
Groundwater and surface water (hereafter: GW and SW) are typically identified
as different compartments of the hydrological cycle and were traditionally often studied and managed
separately. However, despite this separation, these respective fields of
study are usually not considered to be different disciplines. They are often
seen as different specializations of hydrology with a different focus yet
similar theory, concepts, and methodology. The present article discusses how
this notion may form a substantial obstacle in the further integration of GW
and SW research and management.
The article focuses on the regional scale (areas of approximately 103 to
106 km2), which is identified as the scale where integration is
most greatly needed, but ironically where the least amount of fully
integrated research seems to be undertaken. The state of research on
integrating GW and SW research is briefly reviewed and the most essential
differences between GW hydrology (or hydrogeology, geohydrology) and SW
hydrology are presented. Groundwater recharge and baseflow are used as
examples to illustrate different perspectives on similar phenomena that can
cause severe misunderstandings and errors in the conceptualization of
integration schemes. The fact that integration of GW and SW research on the
regional scale necessarily must move beyond the hydrological aspects, by
collaborating with the social sciences and increasing the interaction between
science and society in general, is also discussed. The typical elements of an
ideal interdisciplinary workflow are presented and their relevance with
respect to the integration of GW and SW is discussed.
The overall conclusions are that GW hydrology and SW hydrogeology study
rather different objects of interest, using different types of observation,
working on different problem settings. They have thus developed a different
theory, methodology and terminology. However, there seems to be a widespread
lack of awareness of these differences, which hinders the detection of the
existing interdisciplinary aspects of GW and SW integration and consequently
the development of a truly unifying interdisciplinary theory and methodology.
Thus, despite having the ultimate goal of creating a more holistic approach,
we may have to start integration by analyzing potential disciplinary
differences. Improved understanding among hydrologists of what
interdisciplinary means and how it works is needed. Hydrologists,
despite frequently being involved in multidisciplinary projects, are not
sufficiently involved in developing interdisciplinary strategies and
do usually not regard the process of integration as such as a research topic
of its own. There seems to be a general reluctance to apply a (truly)
interdisciplinary methodology because this is tedious and few immediate
incentives are experienced.
The objective of the present opinion paper is to stimulate a discussion
rather than to provide recipes on how to integrate GW and SW research or to
explain how specific problems of GW–SW interaction should be solved on a
technical level. For that purpose it presents complicated topics in a rather
simplified, bold way, ignoring to some degree subtleties and potentially
controversial issues. |
