Experimental Study on Flow Turbulence Distribution around a Spur Dike with Different Structure [PDF]

, 2012
The spur dike is an important building in river guiding and bank protection. In the present paper, the turbulence intensity distribution around spur dikes with different structures under the same flow condition is studied through model experiment and it ...

Can Environmental Markets Pay for More Sustainable Farm Dams? A Cost–Benefit Analysis

Sustainable Development, EarlyView.
ABSTRACT Farm dams are widespread artificial waterbodies that play a critical role in agricultural water security. Enhancing these systems through sustainable interventions such as fencing, hardened access points, and revegetation can improve water quality and deliver carbon and biodiversity co‐benefits.

The winter 2023/2024 floods in the UK: a hydrological appraisal

Weather, EarlyView.
From October 2023 to March 2024, the UK saw a succession of named storms and low‐pressure weather systems, leading to widespread exceptional river flows throughout. Peak flow records were broken in several catchments, but this event was most notable for its duration and spatial footprint, which resulted in major impacts.

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

Wildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

EFFECTS OF ORIENTATION ANGLE ON FLOW STRUCTURES AROUND SUBMERGED CONTINUOUS SPUR DIKES

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2004
The flow structures around the continuous spur dikes were investigated by using a PIV method. In this study, the orientation angle of spur dike was chosen as a control parameter and it was varied in three ways. The visual images were recorded by a high-speed camera and analyzed with the cross-correlation method.

A Crisis of Representation: Reflections on John Boswell, How Citizens Encounter the Democratic State

The Political Quarterly, EarlyView.
Abstract In this symposium contribution, we subject John Boswell's How Citizens Encounter the Democratic State to the scrutiny warranted by its contribution. While the book offers a rich categorisation of the myriad forms of mundane agency one can observe in the underbelly of the democratic state, we seek to extend the argument by situating it in some ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Transformation of the Agrarian Landscape and Hope in the Central Kalimantan Peatlands

Asia Pacific Viewpoint, EarlyView.
ABSTRACT In Kalimantan, Indonesian Borneo, agrarian state programs and corporate strategies seek to transform indigenous Ngaju Dayak into sedentary farmers. Focusing on the notion of transformation, the paper traces whether and how rural people can engage in struggles against structural injustices.

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

Boreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant
