Zusammenfassung |
Hydrological modelling is the same as developing and encoding a hydrological
theory. A hydrological model is not a tool but a hypothesis. The whole
discussion about the inadequacy of hydrological models we have witnessed of
late, is related to the wrong concept of what a model is. Good models don't
exist. Instead of looking for the "best" model, we should aim at developing
better models. The process of modelling should be top-down, learning from the
data while at the same time connection should be established with underlying
physical theory (bottom-up). As a result of heterogeneity occurring at all
scales in hydrology, there always remains a need for calibration of models.
This implies that we need tailor-made and site-specific models. Only flexible
models are fit for this modelling process, as opposed to most of the
established software or "one-size-fits-all" models. The process of
modelling requires imagination, inspiration, creativity, ingenuity,
experience and skill. These are qualities that belong to the field of art.
Hydrology is an art as much as it is science and engineering. |
