Estimation of Scour Depth at Bridge Piers by Using FASTER Model and Experimental Formulas [PDF]

مهندسی منابع آب, 2017
Bridges are one of the most important river structures. One of the main causes of bridge failure is local scour at bridge piers. Yearly, Many bridges failed around the world because of disregarding hydraulic factors.

On Local Scouring at Single Piers

Scientific Research Communications, 2021
The paper mostly summarizes disperse contributions of the authors published during the last fifteen years on the scour depth at single piers. These contributions rely on unique experiments in the sense that they are systematically longer than most of those found in the literature.

Experimental Study on Local Scour at the Monopile Foundation of an Offshore Wind Turbine under the Combined Action of Wave–Current–Vibration

Journal of Marine Science and Engineering
Monopile foundations are the most widely used offshore wind turbine foundations. The experiments were conducted to investigate the influencing factors of local scour around the monopile under the action of wave–current–vibration.

Local Scour at Bridge Abutments

Journal of King Abdulaziz University-Engineering Sciences, 1998
This paper presents the results of an experilnental investigation of local scour at bridge abutment models of three common shapes placed in laboratory flume with uniform sand with d)l) =0.775 mm. The 1l1uximum scour depths and extent of scour were determined corresponding to clear water conditions.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Study of the time-dependent clear water scour around circular bridge piers

Journal of Hydrology and Hydromechanics, 2017
The local scour around bridge piers influences their stabilities and plays a key role in the bridge failures. The estimation of the maximum possible scour depth around bridge piers is an important step in the design of the bridge pier foundations.

Flow hydrodynamics across open channel flows with riparian zones: implications for riverbank stability [PDF]

, 2017
Riverbank vegetation is of high importance both for preserving the form (morphology) and function (ecology) of natural river systems. Revegetation of riverbanks is commonly used as a means of stream rehabilitation and management of bank instability and ...
