Evaluation of empirical equations for scour downstream grade-control weirs

, 2018
The grade control structures are frequently adopted in the Mountain Rivers and streams to prevent severe bed degradation and channel incision. These structures are constructed as a staircase-like sequence of transverse weirs or bed sills.

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Nutritional properties, traditional uses and potential new applications for the sotol plant (Asparagaceae, Convallarioideae): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Sotol (Dasylirion spp.) is a resilient desert plant that sustains ecosystems, cultures and livelihoods in Chihuahua Desert. Our review highlights its nutritional properties, traditional uses and potential new applications in food, pharmaceuticals, renewable energy and water remediation. By synthesizing evidence across disciplines, we show how sotol can

Sacrificial piles as a countermeasure against local scour around underwater pipelines

Water Science and Engineering
Local scour around pipelines crossing rivers or in marine environments is a significant concern. It can lead to failure of the pipelines resulting in environmental side effects and economic losses.

Increased utilitarian value of invasive species in regions with long invasion history may limit public engagement for invasion control

PLANTS, PEOPLE, PLANET, EarlyView.
Positive perceptions of invasive species can hinder effective management, especially if management efforts that are rooted in scientific theories are misaligned with local ecological knowledge. We documented local ecological knowledge about land invasibility as predicted by invasion biology theories. Participants with greater local ecological knowledge

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.

A Functional Flows Framework for the Terminal Great Salt Lake Basin: Can We Have Our Lake and Drink It Too?

River Research and Applications, EarlyView.
ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...

Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

Remote Sensing in Ecology and Conservation, EarlyView.
Imaging spectroscopy enables large‐scale biodiversity assessment, yet spectral diversity metrics are scale dependent. Across 15 NEON ecosystems, we find that spectral richness increases sub‐linearly from 3600 m2 to 4 km2, whereas spectral divergence shows weak or inconsistent scaling with area, underscoring the importance of scale‐aware interpretation ...

Numerical Investigation of Local Scour Around Bridge Pile-Group Foundations Under Steady Flows

Infrastructures
Local scour around pile-group foundations is a predominant cause of hydraulic instability in bridge engineering. This study employs a fully coupled three-dimensional computational fluid dynamics model to investigate local scour around a 2 × 2 inline pile

Business Model and Sustainable Development Goals for an Innovative Agricultural Waste Management: Distributed Biogas Production

Sustainable Development, EarlyView.
ABSTRACT Technological progress and population growth have increased global pork demand; leading to a rise of methane emission from pig farming, a key contributor to climate change. Anaerobic digestion offers a sustainable solution by converting manure into biogas.
