Application of factor analysis in identification of dominant hydrogeochemical processes of some nitrogenous groundwater of Serbia [PDF]

Geološki Anali Balkanskoga Poluostrva, 2013
Multivariate statistical analyses are used for reducing large datasets to a smaller number of variables, which explain main hydrogeochemical processes that control water geochemistry.

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 ...

Reconstructing Long‐Term Historical Hydrologic Alteration to Support Environmental Flows in Texas

River Research and Applications, EarlyView.
ABSTRACT Understanding and quantifying hydrologic alteration is essential for effective watershed management and ecological conservation. This study developed a modeling framework to predict reference hydrology and assess and model hydrologic alteration across Texas using publicly available geospatial datasets.

Mechanism of Structural Evolution of Limestone of Qinghai–Xizang Plateau Under Coupling Effect of Freeze–Thaw Cycles and Hydrochemical Erosion

Geofluids
The scientific understanding of the evolution of limestone structure under the combined action of freeze–thaw cycles (F-T cycles) and hydrochemical solutions is of great significance for revealing the mechanism of frost damage generation in cold ...

The Return of the Allis Shad (Alosa alosa) to the Lower Navigable Reaches of the Seine: Locks Play a Role

River Research and Applications, EarlyView.
ABSTRACT In France, it is estimated that shads (Alosa spp.) have lost 69% of their historical range, mainly due to disrupted river connectivity. After an absence of one century, signs of their return in the Seine River have been recorded over the past two decades: adult and juvenile specimens have been caught by anglers or recorded at video‐counting ...

Seismic hydrogeology: Review and prospects

Shuiwen dizhi gongcheng dizhi
Seismic hydrogeology, as a cross-disciplinary field studying the interactions between seismic events and groundwater systems, aims to address the lack of systematic review and unclear definition of the scope and connotations within this field. This paper

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.

River Ice Processes Modelling: A Comprehensive Review

River Research and Applications, EarlyView.
ABSTRACT River ice strongly influences hydrology, hydrodynamics, and ecosystems in cold regions, with an impact on flooding, hydropower generation, navigation, and aquatic habitats. Modeling river ice processes is therefore essential for both scientific understanding and operational management.

The Characteristics, Sources, and Geothermal Implications of Sulfur-Containing Nanoparticles in Deep High-Temperature Geothermal Fluids in the Jiyang Depression

Geofluids
Rising global demand for clean energy has elevated the status of geothermal resources as a sustainable renewable energy. Nevertheless, high costs and environmental risks of deep drilling restrict the development of geothermal research. Recent advances in
