Design relationships for maximum local scour depth for bridge pier groups. [PDF]
, 1996 An investigation of local scour at pier groups has been conducted with the aim of developing design recommendations and scour depth prediction equations for the bridge pier groups.

Sedimentology, EarlyView.ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Experimental investigation of the effect of the presence of obstacles at the end of the output keys of the C-type piano key weir on its downstream scour [PDF]
علوم آب و خاکPiano key weirs are a type of non-linear weir that have a higher discharge coefficient than similar linear weirs. These hydraulic structures have a lightweight foundation and a simple structure is designed and installed on dams and drainage channels. Due

Comparison of Erosion and Sedimentation Patterns Facilitated by a Spur Dike and a Triangular-Shaped Vane Structures in a 90° Mild Bend under the Influence of Different Froude Numbers [PDF]
مهندسی منابع آب, 2016 Spur dikes and triangular-shaped vanes are structures that control the erosion of a river’s outer bend by the diversion of flow from there to its center.

Sedimentology, EarlyView.ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Influence of propeller clearance on the jet scour process in restricted water
International Journal of Sediment ResearchRapid development of inland waterways and marine transportation has resulted in the construction of large ships and an increase in ship speed. Consequently, severe local scour erosion of restricted water beds occurs due to propellers, endangering the ...

Prediction of Maximum Local Scour Depth Due to Horizontal Jets of Flushing Gate using Artificial Neural Network [PDF]
Local scour is a serious concern for hydraulic engineers. To maintain the reservoir capacity, flushing accumulated sediment is necessary, resulting in a turbulent and scouring jet from the flushing gate.

Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.ABSTRACT Natural Flood Management (NFM) is increasingly adopted as a sustainable strategy for mitigating flood risk. Among these measures, the installation of leaky wooden dams (LWDs) at catchment scale is a widely used intervention aimed at slowing flow and desynchronising runoff peaks between sub‐catchments, thereby reducing flood magnitude.

SIMULATION OF SCOURING AROUND A VERTICAL CYLINDER DUE TO TSUNAMI [PDF]
Science of Tsunami Hazards, 2017 * Corresponding author radianta@ugm.ac.id ABSTRACT Local scour due to tsunami is damaging especially on shallow foundation. Although relatively in a short duration, tsunami attack may scour material around buildings that led to destruction. A number of
