| Zusammenfassung |
| Sophisticated methods have been developed and become standard in analysing
floods as well as for assessing flood risk. However, increasingly
critique of the current standards and scientific practice can be found both
in the flood hydrology community as well as in the risk community who argue
that the considerable amount of information already available on natural
disasters has not been adequately deployed and brought to effective use. We
describe this phenomenon as a failure to synthesize knowledge that results
from barriers and ignorance in awareness, use and management of the entire
spectrum of relevant content, that is, data, information and knowledge. In
this paper we argue that the scientific community in flood risk research
ignores event-specific analysis and documentations as another source of
data. We present results from a systematic search that includes an intensive
study on sources and ways of information dissemination of flood-relevant
publications. We obtain 186 documents that contain information on the
sources, pathways, receptors and/or consequences for any of the 40 strongest
trans-basin floods in Germany in the period 1952–2002. This study therefore
provides the most comprehensive metadata collection of flood documentations
for the considered geographical space and period. A total of 87.5% of all events
have been documented, and especially the most severe floods have received
extensive coverage. Only 30% of the material has been produced in the
scientific/academic environment, and the majority of all documents (about
80%) can be considered grey literature (i.e. literature not controlled
by commercial publishers). Therefore, ignoring grey sources in flood
research also means ignoring the largest part of knowledge available on
single flood events (in Germany). Further, the results of this study
underpin the rapid changes in information dissemination of flood event
literature over the last decade. We discuss the options and obstacles of
incorporating this data into the knowledge-building process in light of
the current technological developments and international, interdisciplinary
debates for data curation. |
