Tutorial for using hydroPSO to calibrate the GR4J model

, 2020
This tutorial shows how to use the hydroPSO R package (version >= 0.6-0) to calibrate and verify the GR4J hydrological model included in the airGR package, and to perform a basic uncertainty analysis.

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.

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 ...

Can State‐Dependant Residual Modeling Improve Legacy Hydrological Model Simulations?

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Traditional residual post‐processing methods have demonstrated substantial improvements in simulated hydrological response; however, they typically aggregate multiple sources of uncertainty into a single lumped residual and apply uniform statistical treatment across all hydrologic conditions.

Influence of Soil and Land‐Use/Land‐Cover Data Quality on SWAT Parameter Transferability in Small Subtropical Agricultural Watersheds

Hydrological Processes, Volume 40, Issue 6, June 2026.
Does input soil and land‐use quality affect SWAT parameter transfer in neighbouring watersheds? Our proxy‐basin experiment in two small agricultural watersheds under crop–livestock rotations showed that capturing LULC dynamics and refining soil characterization can substantially enhance parameter transferability to ungauged neighbouring watersheds ...

Convection‐Permitting Regional Climate Simulations Reveal Stronger Drying and Snow Loss in Semi‐Arid Mountainous Basins of Morocco

Hydrological Processes, Volume 40, Issue 6, June 2026.
Convection‐permitting simulations (WRF3, 3 km) better represent mountain precipitation and snow processes than coarser regional simulations (WRF20, 20 km). Hydrological simulations forced by WRF3 improve streamflow seasonality and snow‐related hydrological signatures compared to WRF20.

Robust Calibration of Hydrological Models for Simulating Unseen Flood Extremes

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Calibrating conceptual rainfall‐runoff models to predict a catchment's response to extreme rainfall events is a significant challenge, especially when historical data is limited and the event exceeds recorded extremes. This challenge is amplified in non‐stationary environments where the frequency and intensity of extreme rainfall and floods ...
