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. -

Upper Susquehanna River Basin Flood Damage Reduction Study
Final Fish and Wildlife Coordination Act Report Upper Susquehanna Comprehensive Flood Damage Reduction Study Prepared For: U.S. Army Corps of Engineers Prepared By: Department of the Interior U.S. Fish and Wildlife Service New York Field Office Cortland, New York Preparers: Anne Secord & Andy Lowell New York Field Office Supervisor: David Stilwell February 2019 EXECUTIVE SUMMARY Flooding in the Upper Susquehanna watershed of New York State frequently causes damage to infrastructure that has been built within flood-prone areas. This report identifies a suite of watershed activities, such as urban development, wetland elimination, stream alterations, and certain agricultural practices that have contributed to flooding of developed areas. Structural flood control measures, such as dams, levees, and floodwalls have been constructed, but are insufficient to address all floodwater-human conflicts. The U.S. Army Corps of Engineers (USACE) is evaluating a number of new structural and non-structural measures to reduce flood damages in the watershed. The New York State Department of Environmental Conservation (NYSDEC) is the “local sponsor” for this study and provides half of the study funding. New structural flood control measures that USACE is evaluating for the watershed largely consist of new levees/floodwalls, rebuilding levees/floodwalls, snagging and clearing of woody material from rivers and removing riverine shoals. Non-structural measures being evaluated include elevating structures, acquisition of structures and property, relocating at-risk structures, developing land use plans and flood proofing. Some of the proposed structural measures, if implemented as proposed, have the potential to adversely impact riparian habitat, wetlands, and riverine aquatic habitat. In addition to the alternatives currently being considered by the USACE, the U.S. -

Background, Rationale and Outputs/Results Expected: According to Richard Haggerty’s country study on Haiti from 1989, in 1925, 60% of Haiti’s original forests covered the country. Since then, the population has cut down all but an estimated 2% of its original forest cover. The fact that many of Haiti’s hillsides have been deforested has caused several flooding problems for cities and other communities located in critical watershed and flood-plain areas during recent hurricane seasons. The 2008 hurricane season was particularly devastating for Haiti, where over 800 people were killed by four consecutive tropical storms or hurricanes (Fay, Gustav, Hanna, and Ike) which also destroyed infrastructure and caused severe crop losses. In 2004, tropical storm Jeanne killed an estimated 3,000 people, most in Gonaives. -

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.
