URBAN COASTAL FLOOD MITIGATION STRATEGIES for the CITY of HOBOKEN & JERSEY CITY, NEW JERSEY by Eleni Athanasopoulou
©[2017] Eleni Athanasopoulou ALL RIGHTS RESERVED URBAN COASTAL FLOOD MITIGATION STRATEGIES FOR THE CITY OF HOBOKEN & JERSEY CITY, NEW JERSEY By Eleni Athanasopoulou A dissertation submitted to the Graduate School- New Brunswick Rutgers, The State University of New Jersey In partial fulfillment of requirements For the degree of Doctor of Philosophy Graduate Program in Civil and Environmental Engineering Written under the direction of Dr. Qizhong Guo And approved by New Jersey, New Brunswick January 2017 ABSTRACT OF THE DISSERTATION URBAN COASTAL FLOOD MITIGATION STRATEGIES FOR THE CITY OF HOBOKEN & JERSEY CITY, NEW JERSEY by ELENI ATHANASOPOULOU Dissertation Director: Dr. Qizhong Guo Coastal cities are undeniably vulnerable to climate change. Coastal storms combining with sea level rise have increased the risk of flooding and storm surge damage in coastal communities. The communities of the City of Hoboken and Jersey City are low-lying areas along the Hudson River waterfront and the Newark Bay/Hackensack River with little or no relief. Flooding in these areas is a result of intense precipitation and runoff, tides and/or storm surges, or a combination of all of them. During Super-storm Sandy these communities experienced severe flooding and flood-related damage as a result of the storm surge. ii Following the damage that was created on these communities by flooding from Sandy, this research was initiated in order to develop comprehensive strategies to make Hoboken and Jersey City more resilient to flooding. Commonly used flood measures like storage, surge barrier, conveyance, diversion, pumping, rainfall interception, etc. are examined, and the research is focused on their different combination to address different levels of flood risk at different scales. -

Technology Fact Sheet Seawall and Revetment Technologyi
Technology Fact Sheet Seawall and revetment technologyi 1) Introduction In every coastal area and beach in Indonesia, integrated coastal management will be applied. This is a process of coastal natural resource management and environmental services that integrate the activities of government, business and society covering horizontal and vertical planning, preserving land and marine ecosystems, application of science and management, so that this resource management will improve and be sustainable for the surrounding community welfare. Lack of understanding of coastal dynamics will lead the efforts to harness the economic potential even bring up new problems such as erosion and abrasion as well as accretion. Besides, the incidence of sea level rise and tropical storms will also lead to coastal erosion. Various efforts to solve the problems through the development of Seawall and revetment have been and some are being done by government, business and the society. Because the incidence of abrasion and erosion of beaches are scattered throughout Indonesia, the location that has a significant impact will be followed up in advance. Development of Seawall and revetment is one of the appropriate adapt technology in dealing with further damage of coastal and beaches. A) Feasibility of technology and operational necessities Seawall and revetment are structures that were built on coastline as a barrier of the mainland on one side and waters on the other. The function of this structure is to protect and keep the coastline from waves and to hold the soil behind the seawall. The seawall is expected to cease erosion process. On the north coast of Java, many cities are experiencing abrasion and erosion resulting from a decrease of land and sea-level rise. -
New Orleans and Hurricane Katrina. III: the 17Th Street Drainage Canal

Vera-Grunauer, M.ASCE14; and J. Wartman, M.ASCE15 Abstract: The failure of the levee and floodwall section on the east bank of the 17th Street drainage canal was one of the most catastrophic breaches that occurred during Hurricane Katrina. It produced a breach that rapidly scoured a flow pathway below sea level, so that after the storm surge had largely subsided, floodwaters still continued to stream in through this breach for the next two and a half days. This particular failure contributed massively to the overall flooding of the Metropolitan Orleans East Bank protected basin. Slightly more than half of the loss of life, and a similar fraction of the overall damages, occurred in this heavily populated basin. There are a number of important geotechnical and geoforensic lessons associated with this failure. Accordingly, this paper is dedicated solely to investigating this single failure. Geological and geotechnical details, such as a thin layer of sensitive clay that was laid down by a previous hurricane, proper strength characterization of soils at and beyond the toe of the levee, and recognition of a water-filled gap on the inboard side of the sheet pile cutoff wall are judged to be among the most critical factors in understanding this failure. -
Appendix G. Flood Hazard Management Risk Areas
APPENDIX G. FLOOD HAZARD MANAGEMENT RISK AREAS This appendix contains a complete listing of the flooding and erosion related risk areas identified by the River and Floodplain Management Program staff during the preparation of the 2006 King County Flood Hazard Management Plan. The approach to identifying and characterizing these risk areas varied from river to river and was influenced by both the characteristics of each river, and by the professional judgment of the team compiling this information. This risk identification was the first step in the development of project and program proposals contained in Appendices E and F of this Plan. These project and program recommendation are cross referenced in the last columns of this table. In many cases the magnitude of these risks described is not well understood but will be further evaluated through future technical studies and risk assessments.

Decision-Making Chronology for the Lake Pontchartrain & Vicinity
DECISION-MAKING CHRONOLOGY FOR THE LAKE PONTCHARTRAIN & VICINITY HURRICANE PROTECTION PROJECT FINAL REPORT FOR THE HEADQUARTERS, U.S. ARMY CORPS OF ENGINEERS SUBMITTED TO THE INSTITUTE FOR WATER RESOURCES OF THE U.S. ARMY CORPS OF ENGINEERS Douglas Woolley Leonard Shabman March 2008 ii Forward The one-two punch of Hurricanes Katrina and Rita in August and September of 2005 proved calamitous to a vast swath of the U.S. Gulf Coast across the States of Louisiana, Mississippi, Alabama, Florida, and Texas. While still offshore in the Gulf of Mexico, Hurricane Katrina’s 175 mph winds created the highest storm surge yet recorded at landfall in North America. Katrina’s storm surge overwhelmed many of the levees and floodwalls for greater New Orleans designed and constructed by the U.S. Army Corps of Engineers, collectively known as the Lake Pontchartrain & Vicinity Hurricane Protection Project (LP&VHPP). The result was a human tragedy—more than 1,600 people killed or missing and presumed dead, with over 1,250 confirmed deaths in Louisiana alone. In economic terms, the flooding from Katrina represents the costliest natural disaster in U.S. history. Direct flood damages to residential, non-residential, and public properties and infrastructure in greater New Orleans approached $28 billion, with further indirect economic effects and long- lasting socio-economic disruption to the region. In the immediate aftermath of the tragedy, the Secretary of Defense directed that that Army enlist the National Academy of Sciences to conduct a thorough review of the engineering aspects of the performance of the levees and floodwalls in place in New Orleans on August 29, 2005.
