Quantifying Uncertainty in Flood Predictions in Fixed Cartesian Flood Model Due To Arbitrary Conventions in Grid Alignment

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract Digital elevation models generated by sampling and interpolating LiDAR data onto a square grid can produce reliable flood predictions. However, the arbitrary conventions in grid alignment that can introduce uncertainty in flood predictions are frequently overlooked.

Dam‐Induced Alternations of Flow and Sediment Regimes in the Tibetan Plateau: An Example of the Yarlung Tsangpo River

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract Dams heavily regulate the natural hydrological regimes, impacting on riverine ecosystem and local communities. Yet, the impacts of dams on flow and sediment alterations in the alpine basins, such as the Yarlung Tsangpo River with its immense hydropower potential, remain largely understudied due to limited fine‐scale hydrological records. Here,

Time-scale characteristics of Kasai river hydrological regime variability for 1940-1999 [PDF]

International Journal of Innovation and Applied Studies, 17, 531-547 (2016), 2016
The present study was undertaken with the aim of contributing to the characterization of the nonstationary variability of the hydrological regime of the Kasai River using the wavelet analysis for 1940-1999. The rainfalls and discharge over Kasai Basin have marked fluctuations with a perceptible downward trend and some shift around 1950, 1960, 1970 ...

Simultaneous Separation of Runoff Pathways and Storage Times via Coupled Electrical Conductivity Mass Balance and Nonlinear Storage‐Discharge Relationship: Theory and Application Testing

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract Streamflow can be separated into fast runoff and baseflow according to runoff pathways, and also into new and old water according to storage times. Typically, baseflow does not completely overlap with old water, nor does fast runoff completely overlap with new water.

Quantitatively Decoupling the Relationships Between Discharge and Sediment Yield During Flood Events in China's Loess Plateau

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract To clarify changes of discharge (Q) and sediment yield (SSY) during flood events provide critical insights for flood disaster prevention and control. However, our understanding of the long‐term variations and driving factors of Q‐SSY relationships during flood events remains limited.

El Niño-Induced Drought Impacts on Reservoir Water Resources in South Africa

Atmosphere
The ENSO phenomenon is associated with below average rainfall and influences the climate regime of southern Africa. With the advent of climate change, drought frequencies and magnitudes have worsened in the developing world and this in turn negatively ...

River Thermal Dynamics and Heatwaves of Polish Rivers Under Climate Change

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract Progression of global warming poses a significant risk to river ecosystems. However, how river heatwaves' characteristics across complex hydrological systems alter under climate change is still poorly understood. In this study, long‐term reconstructed daily river water temperatures (RWTs) from 125 hydrological stations in 70 rivers across ...

Global Warming Will Increase the Risk of Water Shortage in Northwest China

Earth's Future, Volume 13, Issue 5, May 2025.
Abstract Drylands with fragile ecosystems and severe water shortages are particularly vulnerable to climatic change. Northwestern China (NWC), a typical arid region, faces uncertainty regarding future wetting or drying trends. A comprehensive assessment and projection of these conditions are crucial for water resource management.
