Title          Hydrogeological research: Beginning of the end
               or end of the beginning?

This paper uses citation data to assess whether articles published in key
ground water journals such as Ground Water (GW) and Water Resources Research
(WRR) are impacting research. Citation information was obtained from SCI
Journal Citation Reports and The Web of Science - databases maintained by
the Institute for Scientific Information (ISI), Information extracted from
The Web of Science was processed further to remove corrections to papers,
discussion/replies, and book reviews. Generally, there are many ground water
papers published, but citations of these papers are limited. Approximately
10% to 15% of WRR articles, and 2% to 3% of GW articles attract more than 50
citations in their lifetimes. In both GW and WRR, the top 10% of papers
eventually will contribute nearly half of the total yearly citations.
Another emerging trend is a diminishing emphasis on citations to new work as
compared to work more than 10 years in age. When articles in Ground Water or
Journal of Hydrology cite papers in Water Resources Research, those papers
cite work 10 or more years old half of the time. If one believes that
citations are a measure of science impact, then there is cause for concern.
Research is inefficient with much produced for little gain. On a typical
industrial life-cycle curve, ground water research is likely ranked as
mature and close to aging. At this stage, much work will have been completed
and the number of truly impactful problems will have dwindled to just a few.
