Download or read book Hydraulics of Levee Overtopping written by Lin Li and published by CRC Press. This book was released on 2020-09-20 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthen levees are extensively used to protect the population and infrastructure from periodic floods and high water due to storm surges. The causes of failure of levees include overtopping, surface erosion, internal erosion, and slope instability. Overtopping may occur during periods of flooding due to insufficient freeboard. The most problematic situation involves the levee being overtopped by both surge and waves when the surge level exceeds the levee crest elevation with accompanying wave overtopping. Overtopping of levees produces fast-flowing, turbulent water velocities on the landward-side slope that can potentially damage the protective grass covering and expose the underlying soil to erosion. If overtopping continues long enough, the erosion may eventually result in loss of levee crest elevation and possibly breaching of the protective structure. Hence, protecting levees from erosion by surge overflow and wave overtopping is necessary to assure a viable and safe levee system. This book presents a cutting-edge approach to understanding overtopping hydraulics under negative free board of earthen levees, and to the study of levee reinforcing methods. Combining soil erosion test, full-scale laboratory overtopping hydraulics test, and numerical modeling for the turbulent overtopping hydraulics. It provides an analysis that integrates the mechanical and hydraulic processes governing levee overtopping occurrences and engineering approaches to reinforce overtopped levees. Topics covered: surge overflow, wave overtopping and their combination, full-scale hydraulic tests, erosion tests, overtopping hydraulics, overtopping discharge, and turbulent analysis. This is an invaluable resource for graduate students and researchers working on levee design, water resource engineering, hydraulic engineering, and coastal engineering, and for professionals in the field of civil and environmental engineering, and natural hazard analysis.

This book was released on 2019 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptation to climate change requires a careful evaluation of the infrastructure performance under extreme events in a changing climate. Earthen levees are critical infrastructure systems, which play a vital role to the country’s safety, environment, and economic security. The main objective of this study is to quantitatively assess the integrity of earthen levees subject to extreme precipitation and flooding under a changing climate. A multidisciplinary modeling framework is developed and applied to two earthen levees, Elkhorn and Sherman Island levees, in California. Patterns of extreme precipitation and flooding are obtained for the study areas under current and future climate. A nonstationary framework is employed, which accounts for climate change-induced changes in statistics of future extreme precipitation. The precipitation and flooding data are then applied as hydraulic loads in a set of fully coupled stress-flow finite element simulations to determine the factory of safety (FOS) and probability of failure (Pf) of the levees for different scenarios. The Pf values are used to develop fragility curves, which can provide valuable tools for risk assessments. The modeling framework is used to study three distinct yet interrelated problems. The first problem assesses the performance of the Elkhorn levee using historical and projected future precipitation patterns. The results show iii that Pf increases 3%-12% under the projected extreme precipitation compared to the baseline scenario. The second problem involves quantifying the effects of changes in future streamflow on the fragility behavior of the Elkhorn levee considering multiple modes of failure. For the cases examined, incorporating future floods leads to up to 23% reduction in FOS and 95% increase in Pf. The third problem assesses the fragility behavior of the Sherman Island levee under compound flooding (induced by coastal, fluvial and pluvial processes), an overlooked aspect in the majority of the existing flood hazard analyses. Results show that considering compound flooding leads to 22% and 30% reductions in FOS for 2- and 50-year recurrence intervals, respectively. Using the projected future pluvial flooding increases Pf by 13%. Findings of this research suggest that risk assessments based on historical records can significantly underestimate the levee’s Pf in a changing climate.

Download or read book Hydraulic and Environmental Modelling Estuarine and River Waters written by R.A. Falconer and published by Taylor & Francis. This book was released on 2019-07-23 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1992, this is the second of two volumes on recent advances in the field of hydraulic and environmental modelling, with invited and refereed contributions from an international group of engineers, scientists and planners involved in application, research and development. It covers the estuarine and river waters with parts devoted to: flow processes; flow modelling; salinity intrusion modelling; water quality modelling; sediment transport modelling; expert systems. The first volume covers coastal waters. With the continually increasing interest in the development and application of numerical hydraulic models, their value is especially evident as tools of design and management for flow, pollutant and sediment transport simulation studies in various environments. The readership includes practising engineers and scientists in the water industry, consulting engineers, water companies and the NRA and other government departments, university and polytechnic libraries, staff and students and all other members of the water engineering profession.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Earthen levees are constructed worldwide as flood control infrastructure and are important components of public safety in the areas they protect. Among the factors which negatively impact the stability and serviceability of earthen levees, internal deteriorations are known to be the most critical type of structural problem. A common type of internal deterioration, animal burrows dug into earthen levee embankments are reported to be the cause of failure in many cases of earthen levees breaches. Globally, the annual cost of damage resulting from failure of earthen structures and associated infrastructure due to invasive wildlife activities is estimated to be many billions of dollars. Understanding the mechanisms of wildlife-caused earthen levee failure is a key component of preventing future breaches. Much of the literature in the area of nuisance wildlife investigates the ecological and environmental impacts of animal activities and habitat, however, studies related to failure mechanisms of earthen structures due to invasive wildlife activities are limited and require a geotechnical engineering perspective. This research aims to identify the mechanics that govern the progress of failure within wildlife-induced levees deteriorations. Investigation of the impact of animal burrows on the hydraulic performance and stability of levee structures is performed using centrifuge modeling. Scaled-down earthen levee models with both landside and waterside burrows as well as a benchmark intact levee model are built and tested at 35g during the centrifuge experiments. The centrifuge experiments are monitored and recorded for deformation, seepage, and pore pressure measurements. Particle Image Velocimetry (PIV) analyses are performed on series of images captured during the centrifuge flights to calculate global deformation of the levee models. Finite element models are developed based on the experiments and used to conduct parametric studies on the impacts of burrow configurations on the stability of the deteriorated levees. The studies investigate key parameters which governs levee safety: burrow length, burrow depth and levee side slope ratio. Details and results of the experimental and numerical work are presented in this thesis along with conclusions and recommendations for future research." --
