Inter-comparison of lumped hydrological models in data-scarce watersheds using different precipitation forcing data sets: Case study of Northern Ontario, Canada

Journal of Hydrology: Regional Studies, 2020
Study region: Big East River and Black River watersheds in Northern Ontario, Canada as snow-dominated, data-poor case studies. Study focus: In this study, seven lumped conceptual models were thoroughly compared in order to determine the best performing ...

Intra‐Annual Chlorophyll‐a Dynamics Under Hydroclimatic Extremes Derived From a 44‐Year Baseline: Insights From a Temperate River System (Nakdong River Basin, South Korea)

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Understanding how drought affects phytoplankton dynamics is critical for developing early warning systems. Using standardized drought indices that capture both hydrometeorological extremes, we investigated how hydrological anomalies modulate intra‐annual chlorophyll‐a (Chla) concentrations, a proxy for phytoplankton biomass, in South Korea's ...

Multi‐Source Adaptive‐Fusion Transfer Learning for Streamflow Forecasting in Data‐Scarce Catchments

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Streamflow gauging records remain sparse in many regions, limiting hydrological predictions. Transfer Learning (TL), which uses knowledge from data‐rich sources to improve predictions in data‐scarce targets, has emerged as a promising solution.

How Will Higher Interannual Precipitation Variability Intensify Water Stress Under a Drying Climate?

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Climate change is expected to alter both the mean and variability of precipitation. Hydrological consequences of higher precipitation variability remain less understood than that induced by changes in precipitation mean. This study evaluates the combined effects of changes in annual precipitation mean and variability on runoff and water supply

Determination of the Total Phosphorus Decay Coefficient Based on Hydrological Models in an Artificial Reservoir in the Brazilian Semi-Arid Region

Hydrology
Phosphorus input into surface water is a global concern due to its role in eutrophication, which is especially critical in semi-arid regions with their challenging climatic conditions.

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 ...

The Irish Hydrometric Reference Network, Version 2.0

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Reference hydrometric networks (RHNs) comprise high‐quality flow gauges with long reliable observational records from near‐natural catchments. Their primary role is for detecting changes in the water cycle, due to external drivers including climate change. Here we present an updated RHN for Ireland.

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.
