When the Levees Break: Relief Cuts and Flood Management in the Sacramento-San Joaquin Delta
UC Berkeley Hydrology Title When the levees break: Relief cuts and flood management in the Sacramento-San Joaquin Delta Permalink https://escholarship.org/uc/item/4qt8v88d Authors Fransen, Lindsey Ludy, Jessica Matella, Mary Publication Date 2008-05-16 eScholarship.org Powered by the California Digital Library University of California When the levees break: Relief cuts and flood management in the Sacramento-San Joaquin Delta Hydrology for Planners LA 222 Lindsey Fransen, Jessica Ludy, and Mary Matella FINAL DRAFT May 16, 2008 Abstract The Sacramento-San Joaquin Delta is one of California’s most important geographic regions. It supports significant agricultural, urban, and ecological systems and delivers water to two-thirds of the state’s population, but faces extremely high risks of disaster. Largely below sea level and supported by 1,100 miles of aging dikes and levees, the Delta system is subject to frequent flooding. Jurisdictional and financial disincentives to better flood planning prevent coordination that might otherwise reduce both costs and damages. This study highlights one possible flood mitigation technique called a relief cut, which is an intentional break in a downslope levee to allow water that has overtopped or breached an upslope levee to drain back into the river. This flood management technique is “smart” when located in appropriate areas so that floodwaters can be managed most efficiently and safely after a levee break. We identify four key constraints and make four recommendations for flood management planning. The -

The Hurricane Katrina Levee Breach Litigation: Getting the First Geoengineering Liability Case Right
Richards Final.docx (DO NOT DELETE) 2/10/2012 9:50 AM ESSAY THE HURRICANE KATRINA LEVEE BREACH LITIGATION: GETTING THE FIRST GEOENGINEERING LIABILITY CASE RIGHT † EDWARD P. RICHARDS INTRODUCTION In August 2005, Hurricane Katrina flattened the Gulf Coast from the Alabama border to 100 miles west of New Orleans. The New Or- leans levees failed, and much of the city was flooded. More than 1800 people died,1 and property damage is estimated at $108 billion.2 While Katrina was not the most deadly or expensive hurricane in U.S. history, it was the worst storm in more than eighty years and destroyed public complacency about the government’s ability to respond to disasters. The conventional story of the destruction of New Orleans is that the levees broke because the Army Corps of Engineers (Corps) did not design and build them correctly.

On the Importance of Analyzing Flood Defense Failures
7 E3S Web of Conferences, 03013 (2016) DOI: 10.1051/ e3sconf/20160703013 FLOOD risk 2016 - 3rd European Conference on Flood Risk Management On the importance of analyzing flood defense failures 2 1, Myron van Damme1,a, Timo Schweckendiek1,2 and Sebastiaan N. Jonkman1 1Delft University of Technology, Department of Hydraulic Engineering, Delft, Netherlands 2Deltares, Unit Geo-engineering, Delft, Netherlands Abstract. Flood defense failures are rare events but when they do occur lead to significant amounts of damage. The defenses are usually designed for rather low-frequency hydraulic loading and as such typically at least high enough to prevent overflow. When they fail, flood defenses like levees built with modern design codes usually either fail due to wave overtopping or geotechnical failure mechanisms such as instability or internal erosion. Subsequently geotechnical failures could trigger an overflow leading for the breach to grow in size Not only the conditions relevant for these failure mechanisms are highly uncertain, also the model uncertainty in geomechanical, internal erosion models, or breach models are high compared to other structural models. Hence, there is a need for better validation and calibration of models or, in other words, better insight in model uncertainty. As scale effects typically play an important role and full-scale testing is challenging and costly, historic flood defense failures can be used to provide insights into the real failure processes and conditions. The recently initiated SAFElevee project at Delft University of Technology aims to exploit this source of information by performing back analysis of levee failures at different level of detail. Besides detailed process based analyses, the project aims to investigate spatial and temporal patterns in deformation as a function of the hydrodynamic loading using satellite radar interferometry (i.e. -

Military Technology in the 12Th Century
Zurich Model United Nations MILITARY TECHNOLOGY IN THE 12TH CENTURY The following list is a compilation of various sources and is meant as a refer- ence guide. It does not need to be read entirely before the conference. The breakdown of centralized states after the fall of the Roman empire led a number of groups in Europe turning to large-scale pillaging as their primary source of income. Most notably the Vikings and Mongols. As these groups were usually small and needed to move fast, building fortifications was the most efficient way to provide refuge and protection. Leading to virtually all large cities having city walls. The fortifications evolved over the course of the middle ages and with it, the battle techniques and technology used to defend or siege heavy forts and castles. Designers of castles focused a lot on defending entrances and protecting gates with drawbridges, portcullises and barbicans as these were the usual week spots. A detailed ref- erence guide of various technologies and strategies is compiled on the following pages. Dur- ing the third crusade and before the invention of gunpowder the advantages and the balance of power and logistics usually favoured the defender. Another major advancement and change since the Roman empire was the invention of the stirrup around 600 A.D. (although wide use is only mentioned around 900 A.D.). The stirrup enabled armoured knights to ride war horses, creating a nearly unstoppable heavy cavalry for peasant draftees and lightly armoured foot soldiers. With the increased usage of heavy cav- alry, pike infantry became essential to the medieval army.
