| Zusammenfassung |
| Low flows are often poorly reproduced by commonly used hydrological models,
which are traditionally designed to meet peak flow situations. Hence, there
is a need to improve hydrological models for low flow prediction. This study
assessed the impact of model structure on low flow simulations and recession
behaviour using the Framework for Understanding Structural Errors (FUSE).
FUSE identifies the set of subjective decisions made when building a
hydrological model and provides multiple options for each modeling decision.
Altogether 79 models were created and applied to simulate stream flows in the
snow dominated headwater catchment Narsjø in Norway (119 km2). All
models were calibrated using an automatic optimisation method. The results
showed that simulations of summer low flows were poorer than simulations of
winter low flows, reflecting the importance of different hydrological
processes. The model structure influencing winter low flow simulations is the
lower layer architecture, whereas various model structures were identified to
influence model performance during summer. |
