Effect of submergence ratio of parallel wall on bridge abutment scour

Alexandria Engineering Journal, 2018
Scour at bridge abutment could be the main cause of bridge failures, leading to increased repair costs and reduced accessibility to roads. Thus, study and research on the prediction of scour at bridge abutment and its prevention is of great importance ...

SCOUR NEAR SPILL-THROUGH TYPE ABUTMENT ON CLEAR-WATER SCOUR CONDITION FOR MULTI-SECTION CHANNELS

Journal of Civil Engineering
Scour is a natural phenomenon caused by erosion due to water flow on the alluvial channel bed and channel wall. In fact, scour happened in the bridge abutment is total scour, that is a combination between local scour, general scour, and constriction ...

Performance of microbially induced calcite precipitation (MICP) as a local scour countermeasure for offshore wind turbine monopile foundation

International Journal of Sediment Research
Microbially induced calcite precipitation (MICP) is an emerging method for mitigating scour and erosion. The present study experimentally investigates the efficacy of MICP as a local scour countermeasure for offshore wind turbine monopile foundations ...

Scour around submarine pipes due to high-amplitude transient waves

Water Science and Engineering, 2020
Estimation of scour dimensions below submarine pipelines is a vital step in designing offshore infrastructure. Extreme events like tsunami waves produce strong erosive forces below the underwater pipes, apt to create scour holes, jeopardizing the safety ...

Characteristics of reducing local scour around cylindrical pier using a horn-shaped collar

Journal of Engineering and Applied Science, 2022
Local scour is the major cause of bridge water damage. The sediment in the riverbed around the pier is eroded and transported by water flow, leading to a loss of bridge foundation stability.

Clear-Water Scouring Process in a Flow in Supercritical Regime [PDF]

Journal of Hydraulic Engineering, 2016
AbstractThe aim of this research is to measure the clear-water scouring produced by supercritical flow around a rectangular-shaped obstacle. The initial uniform flow condition without the obstacle is such that the Shields parameter remains slightly lower than critical so that the sediment constituting the mobile bed is not transported.

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology

Advanced Materials Technologies, EarlyView.
The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.

Simultaneous Effect of Collar and Roughness on Reducing and Controlling the Local Scour around Bridge Abutment

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Investigation of local scour around hydraulic structures particularly bridges is of crucial importance in river engineering. Bridge destruction mostly occurs as a result of scour phenomenon around piers and abutments, not because of structural weaknesses.

The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton

Advanced Science, EarlyView.
Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates
