Effects of relative dike hight on flow structures in submerged spur-dike zones [PDF]
To predict and control sediment transport and water quality exchange by using submerged spur-dike, it is necessary to clarify three-dimensional flow structures and instantaneous vortex structures around spur-dike zones.

Hydropeaking Catalyzes Redox Reactions in Impacted Aquifers: A First Field Evidence
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Hydropeaking indicates the sudden and frequent fluctuation of river stage caused by the operation of hydropower plants. This river alteration affects numerous physical, chemical, biological, and ecohydrological processes in surface water bodies.

Global Change Biology, Volume 32, Issue 10, October 2026.Re‐oligotrophication drove strong recovery of macrophyte communities in the Upper Mississippi River, increasing plant diversity and shifting dominance toward submersed species. This ecosystem‐wide transition signals biological recovery from improved water quality.

Impact of Submerged Spur Dike on Migrating Fish Habitat in Bending Branched Shoal
工程科学与技术, 2020 There are many bending branched shoals, which are the main obstacles of navigation, in the upper reaches of the Yangtze River, and the reaches are also the main breeding areas of endangering fish Acipenser sinensis.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.ABSTRACT Environmental integrity is vital for the long‐term preservation of freshwater biodiversity, which is currently among the most threatened on Earth due to anthropogenic pressures such as dam construction. The present study investigated the temporal responses of ostracod communities over 8 years (2017–2024) in the Upper Paraná River floodplain ...

Study on Sediment Sorting around Single Spur-dike with Different Orientations [PDF]
, 2013 This paper presents an experimental study on the impacts of orientation of a spur-dike on the bed topography and sediment sorting process of bed surface around a single impermeable spur-dike. The importance of one governing parameters, the orientation of

علوم و مهندسی آبیاری, 2018 Spur dikes are one of the coastal protection methods. Bandal- like is a local type of spur dikes that would be constructed to improve the water depth for navigation in alluvial rivers. This is a new type of spur dike that is a combination of permeable and impermeable spur dike.

Effect of spur dike length on the horseshoe vortex system and the bed shear stress distribution
, 2015 Turbulent flow structures forming around isolated spur dikes in a horizontal channel are investigated in this study. In the analysis detached eddy simulation is used under fully turbulent incoming flow conditions at a channel Reynolds number of 45,000 ...
