Residual-based hybrid modeling combining GR4J and machine learning for streamflow prediction in data-scarce catchment: case of the Ouémé catchment at Bonou (Benin, West Africa) [PDF]

Proceedings of the International Association of Hydrological Sciences
Accurate streamflow forecasting is essential for water resource management, yet remains challenging in data-scarce regions. This study develops and evaluates a hybrid modeling framework for the Ouémé River basin (Benin) that combines the conceptual GR4J ...

Component Combination Test to Investigate Improvement of the IHACRES and GR4J Rainfall–Runoff Models

, 2021
Rainfall–runoff models are not perfect, and the suitability of a model structure depends on catchment characteristics and data. It is important to investigate the pros and cons of a rainfall–runoff model to improve both its high- and low-flow simulation.

Separating climate change and human activities' effects on flow regime with hydrological model error correction

Ecological Indicators, 2023
Climate change and human activities have markedly altered flow regimes, leading to deleterious consequences for riverine ecosystems. The widely employed hydrological modeling restoration method for conducting flow regime attribution often tends to ...

The skill of seasonal ensemble low-flow forecasts in the Moselle River for three different hydrological models [PDF]

Hydrology and Earth System Sciences, 2015
This paper investigates the skill of 90-day low-flow forecasts using two conceptual hydrological models and one data-driven model based on Artificial Neural Networks (ANNs) for the Moselle River. The three models, i.e. HBV, GR4J and ANN-Ensemble (ANN-E),
