Blue Dunes chronicles the design of artificial barrier islands developed to protect the Mid-Atlantic region of North America in the face of climate change. It narrates the complex, and sometimes contradictory, research agenda of an unlikely team of analysts, architects, ecologists, engineers, physicists, and planners addressing extreme weather and sea level rise within the practical limitations of science, politics, and economics.

Topics discussed include erosion, causes of scour, AASHTO design codes, hydrology, hydraulics, scour analysis, inspection methods, and modern materials technology. Real-world case studies illustrate the concepts presented. The authoritative information in this practical guide will help you to develop more efficient and cost-effective design processes and bridge management systems for river bridges subjected to floods. Flood Scour for Bridges and Highways covers: Floods, scour problems, and mitigation River instability caused by flow obstructions Past failures and bridges vulnerable to failure Geotechnical and hydraulic issues at scour-critical rivers and bridges Hydrology, floods, and scour-critical bridges Estimating scour depths and selecting applicable countermeasures Inspections, ratings, and monitoring countermeasures FHWA, HEC-18, and HEC-23 scour countermeasures as remediation Innovative methods of flood control and disaster management

The United States has one of the largest and costliest flood control systems in the world, even though only a small proportion of its land lies in floodplains. Rivers by Design traces the emergence of the mammoth U.S. flood management system, which is overseen by the federal government but implemented in conjunction with state governments and local contractors and levee districts. Karen M. O'Neill analyzes the social origins of the flood control program, showing how the system initially developed as a response to the demands of farmers and the business elite in outlying territories. The configuration of the current system continues to reflect decisions made in the nineteenth century and early twentieth. It favors economic development at the expense of environmental concerns.O'Neill focuses on the creation of flood control programs along the lower Mississippi River and the Sacramento River, the first two rivers to receive federal flood control aid. She describes how, in the early to mid-nineteenth century, planters, shippers, and merchants from both regions campaigned for federal assistance with flood control efforts. She explains how the federal government was slowly and reluctantly drawn into water management to the extent that, over time, nearly every river in the United States was reengineered. Her narrative culminates in the passage of the national Flood Control Act of 1936, which empowered the Army Corps of Engineers to build projects for all navigable rivers in conjunction with local authorities, effectively ending nationwide, comprehensive planning for the protection of water resources.

Diese Open-Access-Publikation ist ein anwendungsorientiertes Lehr- und Handbuch zur Abflussminderung im landlichen Raum. Meteorologische Extreme wie Durren, Starkregen und UEberschwemmungen haufen sich wegen des Klimawandels. Gleichzeitig steigt der Druck auf unsere Landschaft kontinuierlich, indem sie immer intensiver genutzt und effizienter erschlossen wird. Durch diese Entwicklungen ergeben sich dringende Herausforderungen fur den landlichen Hochwasserschutz und den Erhalt unserer naturlichen Ressourcen Wasser und Boden. Das Buch beschreibt Methoden fur die Planung von Massnahmen zur Abflussminderung. Es ist speziell fur kleine Einzugsgebiete (< 25 km(2)) konzipiert, da gerade dort viele Gemeinden durch die genannten Entwicklungen zunehmend mit Sturzfluten und UEberflutungen konfrontiert sind. Gleichzeitig koennen dezentrale Ansatze zur Abflussminderung hier am meisten bewirken. Das Handbuch richtet sich vornehmlich an Ingenieure, Planer und Berater von Landwirtschaft, Kommunen und Landlicher Entwicklung, soll aber auch Studenten und Wissenschaftlern der relevanten Fachgebiete als Informationsquelle und Nachschlagewerk dienen. Die Autoren: Dr. Simon P. Seibert ist Ingenieuroekologe und hat uber die Entstehung und Modellierung von Hochwasser in Munchen und Karlsruhe promoviert. Seit Mitte 2019 leitet er der Arbeitsgruppe Gebietshydrologie am Bayerischen Landesamt fur Umwelt. Prof. Dr. Karl Auerswald lehrt am Wissenschaftszentrum Weihenstephan fur Ernahrung, Landnutzung und Umwelt der TU Munchen. Seine Forschungsschwerpunkte der vergangenen 40 Jahre sind agraroekologische Prozesse, insbesondere der Wasserhaushalt von Landschaften, Boeden, Pflanzen und Tieren.
