Impact of the Addition of a Shading Algorithm in a Physically Based Conceptual River Hydrological–Temperature Model

River Research and Applications, EarlyView.
ABSTRACT Anthropogenic impacts on the thermal regime of rivers include climate change and deforestation. For the latter, developing modelling tools that can account for the impact of varying vegetation cover on river temperatures is essential. This study describes a new addition to the CEQUEAU hydrological and water temperature model: a shading ...

Evolution of deep groundwater balance and renewability analysis in the North China Plain under new hydrological conditions

Shuiwen dizhi gongcheng dizhi
Groundwater serves as a vital water resource supporting the socio-economic development of the North China Plain. Long-term overexploitation of deep groundwater and a significant decline in groundwater levels have led to a series of ecological and ...

Effects of Sediment‐Control Operations on Fish and Macroinvertebrate Communities in Dam Reservoirs

River Research and Applications, EarlyView.
ABSTRACT Sediments are avoided in many river and dam managements because of their adverse effects on water usage and flood control. Recently, sedimentation control measures, including sluicing, have been employed to manage sediments in river channels and restore communities in dammed rivers.

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Multi‐objective optimization of reservoir refill operate considering energy storage and hydrological conditions

River, EarlyView.
Abstract Optimizing reservoir refill operation rules is crucial for enhancing reservoir sustainability and resilience. This study proposes a refill operation model designed to derive optimal refill guide curves by considering flood risk prevention, maximum storage levels, and the combined benefits of hydropower generation and energy storage.

Future changes in population exposure to snowfall extremes across Eurasia

River, EarlyView.
Abstract Extreme snowfall events have frequently occurred across parts of Eurasia, causing substantial economic losses and severe societal impacts. As global warming intensifies, assessing its potential effect on population exposure to such extremes becomes increasingly crucial. This study employed CMIP6 model datasets and future population projections

Assessment of spatiotemporal trends in groundwater depth and salinity through GIS‐based geostatistical analysis: The case of Aksu Irrigation System in Antalya, Türkiye

River, EarlyView.
The study revealed that while groundwater depth trends were generally risk‐free, electrical conductivity showed localized risks in 38% of the Aksu Irrigation System. Overall, 25% of the area was classified as risky. The integrated GIS‐based approach provides a rapid, objective, and cost‐effective tool for precision water management. Abstract Continuous
