| Zusammenfassung |
| A holy grail of hydrology is to understand catchment processes well enough that
models can provide detailed simulations across a variety of hydrologic
settings at multiple spatiotemporal scales, and under changing
environmental conditions. Clearly, this cannot be achieved only through
intensive place-based investigation at a small number of heavily
instrumented catchments, or by empirical methods that do not fully exploit
our understanding of hydrology. In this opinion paper, we discuss the need
to actively promote and pursue the use of a "large catchment sample" approach to modeling the
rainfall–runoff process, thereby balancing depth with breadth. We examine
the history of such investigations, discuss the benefits (improved process
understanding resulting in robustness of prediction at ungauged locations and
under change), examine some practical challenges to implementation and,
finally, provide perspectives on issues that need to be taken into account
as we move forward. Ultimately, our objective is to provoke further
discussion and participation, and to promote a potentially important theme
for the upcoming Scientific Decade of the International Association of
Hydrological Sciences entitled Panta Rhei. |
