Process-based hydrological models have a long history dating back to the 1960s. Criticized
by some as over-parameterized, overly complex, and difficult to use, a more nuanced view is …

Transit time is a fundamental catchment descriptor that reveals information about storage,
flow pathways and source of water in a single characteristic. Given the importance of transit …

It is challenging to accurately differentiate and simulate different runoff components yielded
under the saturation-excess and infiltration-excess mechanisms in semi-arid and semi …

Ambiguities in the representation of environmental processes have manifested themselves
in a plethora of hydrological models, differing in almost every aspect of their …

We simulate the water balance dynamics of 308 catchments in Austria using a lumped
conceptual model involving 11 calibration parameters. We calibrate and verify the model for …

Hydrological drought events have very different causes and effects. Classifying these events
into distinct types can be useful for both science and management. We propose a …

Hydrology does not yet possess a generally agreed upon catchment classification system.
Such a classification framework should provide a mapping of landscape form and hydro …

Computer models, especially conceptual models, are frequently used for catchment
hydrology studies. Teaching hydrological modeling, however, is challenging, since students …

Hydrological models must be reliable and robust as these qualities influence all applications
based on model output. Previous studies on conceptual rainfall–runoff models have shown …

One decade after the first publications on multi-objective calibration of hydrological models,
we summarize the experience gained so far by underlining the key perspectives offered by …
