Temporal variation of clear-water scour at compound Abutments

Ain Shams Engineering Journal, 2016
Most of actual abutments in rivers are built on foundation, while there is limited number of study available on the effects of the foundation on the local scour.

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

River Research and Applications, EarlyView.
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

Laboratory Flume Experiments on the Formation of Spanwise Large Wood Accumulations: Part II—Effect on local scour

Water Resources Research, 2019
In this second companion paper, hydraulic model tests were conducted to analyze local scour due to natural spanwise large wood (LW) accumulations. Spanwise accumulations were modeled using a vertical barrier, similar to a LW retention rack in prototype ...

Temporal evolution of jet induced scour depth in cohesionless granular beds and the phenomenological theory of turbulence

The Physics of Fluids, 2018
In this work, we investigate the temporal evolution of the jet-driven scour depth in a pothole lying on a cohesionless granular bed by using diverse approaches.

Reusing health records from farm animal practices at scale: A potential complementary method of surveillance

Veterinary Record, EarlyView.
Abstract Background Disease in primary care frequently represents a surveillance blind spot, particularly for diseases affecting farm animals. Methods Electronic health records (EHRs) were collected from four farm animal veterinary practices in Wales (February 2024‒January 2025) as part of a pilot study.

Designing Improved Sediment Transport Visualizations [PDF]

, 2013
Monitoring, or more commonly, modeling of sediment transport in the coastal environment is a critical task with relevance to coastline stability, beach erosion, tracking environmental contaminants, and safety of navigation.

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

Journal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Experimental investigation of scour downstream of a type A trapezoidal piano key weir under free and submerged flow conditions

Journal of Hydrology and Hydromechanics
In this paper, the scour downstream of a trapezoidal Piano key weir (PKW) is investigated under free and submerged flow conditions. For this purpose, an experimental model was used in a laboratory channel with a length of 10 m, width of 0.75 m, and ...

Effects of flow regime on the young stages of salmonid fishes. Summary and conclusions based on results for 1981-1985 [PDF]

, 1985
The main British salmonid species spawn in clean gravel in streams and rivers, many of them in the upland areas of Britain. The earliest stages of the life cycle (eggs and alevins) spend some months within the gravel of the river bed.

Evaluation and Prediction of the Scour Depth of Bridge Foundations with HEC-RAS Numerical Model and Empirical Equations (Case Study: Bridge of Simineh Rood Miandoab, Iran)

, 2019
Today, scouring is one of the significant issues in river and coastal engineering. Each year, many bridges around the world destroy due to neglecting hydraulic elements.
