Energy Dissipation Potentials of Grouped Spur Dikes in an Open Channel
Water Resources Management, 2023 Spur dikes are frequently preferred fow regulation structures, especially for open channels and coastal morphology due to their ease of application and economics. Since spur dikes placed on the edge of the stream isolated (single) or in groups do not have a length across the entire channel width, they can also play the role of a semi-permeable weir in ...

Velocity Field Analysis of a Channel Narrowed by Spur-dikes to Maximize Power Output of In-stream Turbines [PDF]
Journal of Sustainable Development of Energy, Water and Environment Systems, 2018 Decentralized energy is growing in importance with time. The electricity being needed even in the most remote places, far from power stations, increases the importance of small power production devices such as micro-hydro devices like turbines.

Tidal Bore Scour around a Spur Dike
Journal of Marine Science and Engineering, 2022 Tidal bores are a natural phenomenon with high flow velocity and destructive potential. A spur dike is a widely used river regulation and embankment protection structure that minimizes erosion, promotes deposition, and protects riverbanks. However, the scouring mechanism around a spur dike under the action of a tidal bore is not fully understood, and ...

Experimental study of layout of spur dike as ice-proof structure in curved channel
Shuili Shuiyun Gongcheng Xuebao, 2018 The concave bank of curved channel is easily eroded or collapsed under the impact of ice floes, and its bank revetment will also be damaged and lose its function of protection under the impact of ice floes.
