| Usually, hydrological models are calibrated and validated to relative short-term datasets of years to several decades. For these relative short durations, model parameters appear to be stable for calibration and validation periods as long as watershed properties (e.g. landuse) and climatic conditions do not change. A few studies have shown that the assumption of temporal stability of watershed model parameters is violated in long-term modeling experiments with strong implications for climate impact analysis (e.g. Merz et al., 2011). However, rarely has the time stability been tested in long-term model applications of more than 100 years. The question then arises if the resulting model uncertainty still allows the detection and attribution of observed long-term changes. | Usually, hydrological models are calibrated and validated to relative short-term datasets of years to several decades.
