A comparative assessment of cluster-based regionalization approaches using conceptual rainfall–runoff models

Scientific Reports
Accurate streamflow prediction in ungauged catchments remains a central challenge in hydrology. We investigated the utility of regionalization methods to explore how hydrologically informed clustering influences parameter transferability and performance ...

Evaluating Multi‐Model and Multi‐Metric Approaches to Low‐Flow Simulation in Irish Catchments

Hydrological Processes, Volume 40, Issue 2, February 2026.
Daily streamflow from 125 catchments was simulated using 47 conceptual models available in MARRMoT framework. The models were calibrated using two objective functions (log NSE and inverse KGE) focusing low flows. Model performances and choice of objective function were assessed against 18 catchment characteristics. ABSTRACT Climate change has increased

Regionalization of a Distributed Hydrology Model Using Random Forest

Hydrological Processes, Volume 40, Issue 2, February 2026.
Distribution of model parameters appoximated by Random Forest at different spatio‐temporal scales. ABSTRACT This study employs a Random Forest machine learning model in conjunction with a process‐based hydrological model for streamflow regionalisation.

Assessment of current and future trends in water resources in the Gambia River Basin in a context of climate change

Environmental Sciences Europe
Accurate assessment of water resources at the watershed level is crucial for effective integrated watershed management. While semi-distributed/distributed models require complex structures and large amounts of input data, conceptual models have gained ...

A state-space representation of the GR4J rainfall-runoff model

, 2017
The aim of this presentation is to detail a state-space representation of the simple GR4J model. The state-space representation aims to represent GR4J by an ODE system which provides the internal variables of the model at all times. We will present here the choices made to adapt GR4J to the state-space formulation and to numerically solve this system ...
