Water and carbon balances in a hemi-boreal forest

Metsanduslikud Uurimused, 2023
The carbon and water fluxes and their inter-relations are key aspects of ecosystem dynamics. In this study, regionalization was used in transferring parameters from the GR4J-Cemaneige model calibrated in Reola hydrographic basin to predict daily flows in

Enhancing hydrological modeling with bias-corrected satellite weather data in data-scarce catchments: a comparative analysis of SWAT and GR4J models

Frontiers in Water
Hydrological models are widely used to assess climate change effect on water resources at the catchment scale. However, data scarcity is one of the main challenges faced by hydrological modelers especially in developing countries.

Assessment of the suitability of rainfall–runoff models by coupling performance statistics and sensitivity analysis

Hydrology Research, 2017
Conceptual rainfall–runoff models are widely used to understand the hydrologic responses of catchments of interest. Modellers calculate the model performance statistics for the calibration and validation periods to investigate whether these models serve ...

Toward a Multi‐Representational Approach to Prediction and Understanding, in Support of Discovery in Hydrology

Water Resources Research, 2023
Key to model development is the selection of an appropriate representational system, including both the representation of what is observed (the data), and the formal mathematical structure used to construct the input‐state‐output mapping.

Modelling High‐Alpine Karst Runoff With Coupled Snow Models of Different Complexity Levels at Mount Zugspitze

Hydrological Processes, Volume 40, Issue 8, August 2026.
Two hydrological model configurations with contrasting snow process complexity were evaluated in a high‐alpine, snow‐dominated karst catchment (2014–2025) at Mount Zugspitze (Germany). Despite comparable discharge simulation performance and water balances, the models show substantial differences in internal process representation.

Why Does Runoff From Some Catchments Not Recover After a Prolonged Drought?

Hydrological Processes, Volume 40, Issue 7, July 2026.
This study investigates the hydrological non‐stationarity in the Victorian state of Australia, using water balance analysis and a modelling experiment with observed hydroclimate and remotely sensed data over 1982–2020 from 120 catchments. The hydrological non‐stationarity is much more significant in North‐West Victoria.

Improving Daily Runoff Prediction Using a Novel Two‐Step Post‐Processing Method of Frequency Distribution Curve Correction

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Offsets and distributional discrepancies between runoff simulations and observations were two important error sources which remarkably degraded runoff prediction performance of hydrological models. However, traditional single post‐processing correction methods were difficult to reduce these two error sources simultaneously due to their ...
