Evaluation of Precipitation Products by Using Multiple Hydrological Models over the Upper Yellow River Basin, China

Remote Sensing, 2020
In this study, 6 widely used precipitation products APHRODITE, CPC_UNI_PRCP, CN05.1, PERSIANN-CDR, Princeton Global Forcing (PGF), and TRMM 3B42 V7 (TMPA), were evaluated against gauge observations (CMA data) from 1998 to 2014, and applied to streamflow ...

Annual Streamflow and Flood Event Simulation for Future Water Supply—A Multiple Lines of Evidence Approach

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract Effective water resource management under climate change is dependent on reliable modeling of future water availability, yet significant uncertainties remain due to shifting precipitation patterns and limitation in climate modeling. This study investigates a multiple‐lines‐of‐evidence approach aimed at reducing the uncertainty in projections ...

A novel framework for analysing river planform characteristics in data‐scarce regions using remote sensing data

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Using a three‐step framework of data preprocessing, analysis and interpretation, we provide insights into the seasonal and annual pattern of morphological changes, the overall bed form and dynamics and the location of morphological uniform river sections to assess the current morphological river state in data‐scarce regions.

Evaluating Evapotranspiration Simulation Performance in 30 Conceptual Hydrological Models: Insights Into ET Representation Across Diverse Climates

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Existing comparative studies on conceptual hydrological model structures have generally focused on streamflow, with less attention to evapotranspiration (ET). Yet, appropriate ET representation in conceptual models is crucial for obtaining reliable hydrological simulations, especially under climate change and in ungauged basins.

Can Conceptual Rainfall‐Runoff Models Capture Multi‐Annual Storage Dynamics?

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Conceptual rainfall‐runoff models are widely used for hydrological applications, yet many fail to capture multi‐annual storage dynamics that are critical during prolonged droughts or shifting climate conditions. This study investigates whether specific structural components enable models to represent such long‐term behavior.

Analyse critique et reformulation mathématique d'un modèle pluie-débit (GR4J)

, 1999
GR4J is an empirical lumped rainfall-runoff model with four parameters which has been developed based on a daily time step. This model allows the generation of outflows in the catchment from the input sériés of daily rainfalls.
