A study of the effect of local scour on the flow field near the spur dike
Theoretical and Applied Mechanics LettersThe flow field near a spur dike such as down flow and horseshoe vortex system (HVS) are susceptible to the topographic changes in the local scouring process, resulting in variation of the sediment transport with time.

River Research and Applications, EarlyView.ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed

Local scour around a vertical pile caused by a jet
, 1995 This study is a preliminary investigation of local scour around a pile caused by a ship propeller. As a first approximation, the propeller generated flow is simulated using a circular jet.

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 ...

Investigating the Local Scour around Group Bridge Piers in Cohesive Soils
علوم آب و خاک, 2019 One of the main reasons for bridge failure is the local scour around the pier. Pier groups are popular in the structural designs due to economical and geotechnical reasons.

River, EarlyView.This figure elaborates the scientific connotation and systematic construction path of ecological dams. Adopting a full‐cycle analysis framework centered on ecological impacts and benefits throughout the project lifecycle, it covers four key stages from planning to post‐completion, with core focuses on risk avoidance, impact control, ecological health ...

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.

Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands
Sustainable Development, EarlyView.ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing

Bridge Pier Scour in Tidal Environments [PDF]
, 2006 Scour depths in estuaries are often estimated using imprecise models that were developed for riverine systems and do not consider the various processes responsible for the removal of sediment in a tidal system.
