Hydraulics of Levee Overtopping

Earthen levees are used to protect against floods, but overtopping, surface erosion, internal erosion, and slope instability can cause failure. This book presents a cutting-edge approach to understanding overtopping hydraulics under negative free board and levee reinforcing methods, including soil erosion test, full-scale laboratory overtopping hydraulics test, and numerical modeling. It is a valuable resource for graduate students and researchers, as well as professionals in civil and environmental engineering and natural hazard analysis.

Earthen levees are a crucial defense system against periodic floods and high water levels caused by storm surges. However, their effectiveness can be compromised by various factors, including overtopping, surface erosion, internal erosion, and slope instability. Overtopping occurs when water exceeds the levee crest elevation, leading to the formation of fast-flowing, turbulent water velocities on the landward slope. This can damage the protective grass covering and expose the underlying soil to erosion, ultimately leading to the loss of levee crest elevation and the potential breaching of the protective structure.

To ensure the viability and safety of levee systems, it is essential to protect them from erosion by surge overflow and wave overtopping. This book offers a comprehensive approach to understanding overtopping hydraulics under negative free board of earthen levees. It combines soil erosion test, full-scale laboratory overtopping hydraulics test, and numerical modeling to analyze the mechanical and hydraulic processes governing levee overtopping occurrences. The topics covered include surge overflow, wave overtopping, their combination, full-scale hydraulic tests, erosion tests, overtopping hydraulics, overtopping discharge, and turbulent analysis.

This book is particularly valuable for graduate students and researchers in the field of levee design, water resource engineering, and coastal engineering. It provides a detailed understanding of the mechanisms behind levee overtopping and offers innovative engineering approaches to reinforce overtopped levees. By addressing these critical issues, the book contributes to the development of more resilient and sustainable infrastructure for protecting communities from the impacts of flooding.
