| Zusammenfassung |
| Hydrological processes do not stop at country borders, whereas hydrological data sets
(released by national hydrological surveys) cover single countries only. Compiling up-to-date
hydrological data on a trans-national scale usually involves difficulties, for example
highly-varying file formats and licence restrictions.
We developed an R package called drought2015 to describe the complete spatial extent
of the streamflow drought that hit parts of Europe in 2015. The key concept is to distribute the
package to every participating country and ask only for the data needed to carry out the final
analysis. By enabling the participants to easily and autonomously perform the computation,
instead of requesting complete streamflow records, all partners showed a willingness to
cooperate.
drought2015 enhances the well-established package lfstat with country-specific import
routines for national file formats, specialised functions to easily compare low flow extremes
and convenient plotting methods.
Enforcing a uniform data structure and a consistent methodology in the distributed
computation has enabled the data collection and facilitated the interpretation of the results. It
became apparent that countries are much more willing to share derived data rather than the
original raw data sets. |
