| Zusammenfassung |
| The evaluation of hydrologic model behaviour and performance is commonly made
and reported through comparisons of simulated and observed variables.
Frequently, comparisons are made between simulated and measured streamflow at
the catchment outlet. In distributed hydrological modelling approaches,
additional comparisons of simulated and observed measurements for
multi-response validation may be integrated into the evaluation procedure to
assess overall modelling performance. In both approaches, single and
multi-response, efficiency criteria are commonly used by hydrologists to
provide an objective assessment of the "closeness" of the simulated behaviour
to the observed measurements. While there are a few efficiency criteria such
as the Nash-Sutcliffe efficiency, coefficient of determination, and index of
agreement that are frequently used in hydrologic modeling studies and
reported in the literature, there are a large number of other efficiency
criteria to choose from. The selection and use of specific efficiency
criteria and the interpretation of the results can be a challenge for even
the most experienced hydrologist since each criterion may place different
emphasis on different types of simulated and observed behaviours. In this
paper, the utility of several efficiency criteria is investigated in three
examples using a simple observed streamflow hydrograph. |
