Book Description
Sponsored by the Water Resources Engineering (Hydraulics) Divsion of ASCE. This collection contains 75 papers and 321 abstracts presented at conferences sponsored by the Water Resources Engineering (Hydraulics) Division of ASCE from 1991 through 1998. The collection contains many new and expanded versions of the original papers and is designed to assist the practitioner with the concepts in evaluating stream instability and scour at bridges. Topics include: history of bridge scour research; bridge scour determination; stream stability and geomorphology; construction scour; instrumentation for measuring and monitoring; field measurement; computer and physical modeling of bridge scour; scour at culverts; and economic and risk analysis. One important paper contains 384 field measurements of local scour at piers made by the U.S. Geological Survey.

Book Description
This report explains the use of the Erodibility Index Method (also known as Annandale's Method) to calculate bridge pier scour. The method can be used to predict scour in any earth material, including rock and cohesive and noncohesive soils. Earth material properties are represented by a geo-mechanical index that integrates the role of material mass strength, block/particle size, internal shear strength and orientation in quantifying the relative ability of earth material to resist scour. A relationship between the geo-mechanical index and the erosive power of water defines the scour threshold that is used in the scour calculations. By comparing the erosive power that is required to scour an earth material (obtained from the threshold relationship) with the erosive power that is available at the base of a bridge pier, it is possible to calculate scour depth. The report outlines the methods that are used to quantify the geo-mechanical index and those that are used to estimate the erosive power of water flowing around bridge piers, and explains how to calculate scour depth. Application of the method is illustrated with an example.

Book Description
"This report provides a methodology for estimating the time rate of scour and the design scour depth for a bridge founded on rock, as well as design and construction guidelines for application of the methodology. It will be of interest to hydraulic, bridge, and geotechnical engineers responsible for designing bridge foundations on rock or maintenance engineers concerned about existing bridges founded on erodible rock."--Foreword.

Book Description
This book examines the digitalization of rock scour engineering at dams and hydraulic structures. It outlines the current digitalization (technologies, applications, issues) in rock engineering, as well as the digital evolution that has strongly characterized the development of computational methods in state-of-the-art rock scour over recent years. The challenges of rock scour digitalization are also discussed, such as parametric standardization, real-time data acquisition, data analysis and interpretation, quantitative rock mass indices, new ways of thinking and digital twin implementation. Further, it presents the major components and characteristics that are needed to develop an environment that implements rock scour digitally into dam safety procedures and dam risk analyses, such as IT platforms, database availability, topology, physics, computational methods, phase coupling, accessibility, portability, reliability, real-time and ahead-of-time implementations and more. Features: Provides an overview of physics-based computational methods that have been developed by the engineering community over the last 20 years, which can easily be implemented digitally into cloud-based platforms. Offers examples of the next-generation computational environment, combining both real-time computational power and an up-to-date scour database allowing new parametric refinements. Includes several case studies of real-life rock scour. Presents the latest Digital Twin developments, which are novel and new to dam operations.

Book Description
The mechanisms and behaviour of the scour process is a challenging subject, and one which is expertly dealt with in this informative, illustrated volume. Specifically, this book addresses issues relating to computing and controlling the scour process near hydraulic structures, and pays special attention to the time-dependent character of the scour processes and the predictability of scour relations. Providing information on the latest developments in scouring, this text is intended for practising hydraulic engineers.

Book Description
Scouring is an engineering problem caused by exposing a structure's foundation to moving water, eventually causing weakness, collapse or flooding. This reference shows civil engineers how to utilize state-of-the-art techniques to analyze, predict, and prevent scour for all earth materials. Valuable case studies
