Available in PDF, EPUB and Kindle. Book excerpt: The results of laboratory experiments on scour around circular piers in cohesionless bed material at high Froude numbers, F, up to 1.5 are presented. The scour depths in sediment transport regime (F is greater than F sub c) first slightly decreases and then increases with the increase in the Froude number. A formula to predict the scour depth at Froude numbers (F-F sub c) is equal to or greater than 0.15, is developed. The limitations of some of the existing predictors of local scour are discussed, and a new formula to predict the maximum clearwater scour is proposed.

This book was released on 2020-02-06 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2019 in the subject Physics - Mechanics, University of Engineering & Technology Peshawar, language: English, abstract: The objective of the study is to conduct laboratory model testing to investigate and compare scour hole depth of the diamond, square and elliptical scaled model of bridge piers in a cohesion less bedding material under clear water and to propose the most efficient cross section of the bridge pier, having less Local scour around piers under steady clear-water condition was studied experimentally for a variety of configuration, including different sizes and shapes of piers. Total number of forty experiments were performed in the flume using diamond, square and elliptical shape. The scouring around the square shape was found maximum and at elliptical shape was the least. The main reason was obstruction in flow area that was more in case of the square and less in case of the elliptical shape. However, the diamond shaped has the intermediate scouring under same condition. Local scour is a complex phenomenon involving three-dimensional flow, typically developed around piers founded in movable bed rivers. Local scour can lead to partial failure or to collapse of bridge piers because of the high flood velocity. The cost of large bridges, with common and special complex piers, justifies carrying out an accurate prediction of scour depth, for both economic and safety reasons, which in turn leads to the interest of hydraulic engineers in predicting the equilibrium scour depth.

Download or read book Experimental and Numerical Study of Local Scour Around Side-by-side Bridge Piers Under Ice-covered Conditions written by Mohammad Reza Namaee and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Local scour around piers and abutments is one of the main causes of the collapse of many bridges constructed inside rivers. Many researchers have conducted various studies to predict the maximum depth of a scour hole around bridge piers and abutments. However, most of them have been done in small-scale laboratory flumes and specifically for the open channel condition. Besides, most of the existing research on bridge piers uses uniform sediment which is not an appropriate representative of natural river systems. This can result in excessively conservative design values for scour in low risk or non-critical hydrologic conditions. The most severe cases of bridge pier scouring occur in cold regions when the surface of water turns into ice in which, an additional boundary layer is being added to the water surface, which leads to significant changes in the flow field and scour pattern around bridge piers. Ice cover also causes the maximum flow velocity to move closer to the channel bed.

Available in PDF, EPUB and Kindle. Book excerpt: Amid increasing interactions with other disciplines and technical advances for detecting, monitoring, and modeling fluvial landscape origin, dynamics, and diversity, a number of scientific works have come out and nested in globally recognized edited books. This book is an attempt in this regard, where a few precise regular research works from diverse disciplinary expertise from around the globe are compiled as chapters. In this collective effort, the application of geoinformatics, field data on natural rivers, instrumentation, use of analytic tools, scientific techniques, numerical models, case studies, illustrations, etc. in understanding formative processes and appraising fluvial landscapes will hopefully provide insight into the current practice of fluvial geomorphology and may guide fruitful and coherent scientific enquiry into the field.
