On the 13 down-drift side, the coastline is set-back. This is often believed to be caused by increased 14 erosion via the ‘terminal groyne effect’, resulting in rapid land loss. This paper examines 15 whether the terminal groyne effect always occurs down-drift post defence construction 16 (i.e. whether or not the retreat rate increases down-drift) through case study analysis. 17 18 Nine cases were analysed at Holderness and Christchurch Bay, England. Seven out of 19 nine sites experienced an increase in down-drift retreat rates. For the two remaining sites, 20 retreat rates remained constant after construction, probably as a sediment deficit already 21 existed prior to construction or as sediment movement was restricted further down-drift. 22 For these two sites, a set-back still evolved, leading to the erroneous perception that a 23 terminal groyne effect had developed. Additionally, seven of the nine sites developed a 24 set back up-drift of the initial groyne, leading to the defended sections of coast acting as 1 25 a hard headland, inhabiting long-shore drift.

  • Overview of Connecticut's Coastal Management Program
    Overview of Connecticut’s Coastal Management Program Coastal Management in Connecticut - What is it all about? We all need Connecticut's coast for all of the services it provides for recreation, tourism, commercial activities, and enjoyment of its resources, all of which benefit the state economically. We all use our coast in one way or another, so we all have to work together to ensure it remains available for future generations. That is where coastal management comes in to guide activities taking place where the land meets the sea. In the case of Connecticut, our emphasis is on balancing protection of the fragile coastal resources of the Long Island Sound ecosystem with sustainable economic uses of the shoreline. Coastal management in Connecticut is a comprehensive, cooperative program that functions at all levels of government. Connecticut's Coastal Management Program is administered by the Department of Energy and Environmental Protection (DEEP) and is approved by the National Oceanic and Atmospheric Administration (NOAA) under the federal Coastal Zone Management Act. Under the statutory umbrella of Connecticut’s Coastal Management Act (CCMA), enacted in 1980, the Coastal Management Program ensures balanced growth along the coast, restores coastal habitat, improves public access, protects water-dependent uses, public trust waters and submerged lands, and promotes harbor management and facilitates research. The Coastal Management Program also regulates work in tidal, coastal, and navigable waters and tidal wetlands under CCMA (Sections 22a-90 – 22a-112 of the Connecticut General Statutes (CGS)), the Structures Dredging and Fill statutes (CGS Sections 22a-359 – 22a-363f) and the Tidal Wetlands Act (CGS Sections 22a-28 – 22a-35).

  • Environmentally Friendly Coastal Protection the ECOPRO Project Abstract
    Environmentally Friendly Coastal Protection The ECOPRO Project Brendan Dollard1 Abstract In the battle to preserve land against the ravages of the sea man has created many inappropriate protection structures on the coast. Often the coastline which is being protected is, inherently, in dis-equilibrium with nature. When combined with the increased recreational usage of the coastal zone, the rise in sea level and the increased incidence of storms, accelerated erosion rates are often the result. The Environmentally Friendly Coastal Protection project, or ECOPRO for short, developed a coastal erosion assessment method for the non-specialist. It devised a system for optimising erosion monitoring and developed a guide to select of an appropriate coastal protection response. The project results are contained in the ECOPRO Code of Practice. This 320-page guide explains the steps involved in assessing and monitoring coastal erosion problems, planning protective actions and evaluating their environmental impact. Prepared by the Offshore & Coastal Engineering Unit of Enterprise Ireland, it is the result of four years of work which was supported under the EU LIFE Programme and drew on expertise from Ireland, Northern Ireland and Denmark. This paper presents details of the project and the development of the Code. 1. Introduction In recent years it has become accepted that the coastline is a valuable natural resource which needs careful and sensitive management. This is especially so in the case of small island countries where the coastal zone has a direct and major influence on the economic welfare of the country. Coastal erosion has always been seen as one of the main threats to this resource and for centuries man has been fighting what was perceived as the ravages of the sea.

  • New York State Coastal Management Program and Final Environmental
    NEW YORK STATE COASTAL MANAGEMENT PROGRAM AND FINAL ENVIRONMENTAL IMPACT STATEMENT This document incorporates all of the approved routine program changes from 1982 to 2020. Prepared by: Office of Coastal Zone Management National Oceanic and Atmospheric Administration Department Of Commerce 3300 Whitehaven Street, N.W. Washington, D.C. 20235 and New York Department of State 99 Washington Avenue, Suite1010 Albany, New York 12231‐0001 The preparation of this publication was financed in part through the office of Coastal Zone Management, NOAA. DESIGNATION: Final Environmental Impact Statement TITLE: Proposed Federal Approval of the New York Coastal Program ABSTRACT: The State of New York has submitted its Coastal Program to the Office of Coastal Zone Management for approval. Approval would allow program administrative grants to be awarded to the State, and would require that Federal actions be consistent with the program. This document includes a copy of the program (Volume 1), which is a comprehensive management program for coastal land and water use activities. It consists of numerous policies on diverse management issues which are administered under existing State laws and is the culmination of several years of program development. New York’s coastal policies either: promote the beneficial use of coastal resources, prevent their impairment, or deal with major activities that substantially affect numerous resources. The program will improve decision-making processes used for determining the appropriateness of actions in the coastal area. Approval and implementation of the program will enhance governance of the State’s coastal land and water areas and uses according to the coastal policies and standards contained in the existing statutes, authorities and rules.

  • Coastal Management Software to Support the Decision-Makers to Mitigate Coastal Erosion
    Journal of Marine Science and Engineering Article Coastal Management Software to Support the Decision-Makers to Mitigate Coastal Erosion Carlos Coelho * , Pedro Narra, Bárbara Marinho and Márcia Lima RISCO & Civil Engineering Department, Aveiro University, Campus Universitário de Santiago, 3810-193 Aveiro, Portugal; [email protected] (P.N.); [email protected] (B.M.); [email protected] (M.L.) * Correspondence: [email protected] Received: 4 December 2019; Accepted: 8 January 2020; Published: 11 January 2020 Abstract: There are no sequential and integrated approaches that include the steps needed to perform an adequate management and planning of the coastal zones to mitigate coastal erosion problems and climate change effects. Important numerical model packs are available for users, but often looking deeply to the physical processes, demanding big computational efforts and focusing on specific problems. Thus, it is important to provide adequate tools to the decision-makers, which can be easily interpreted by populations, promoting discussions of optimal intervention scenarios in medium to long-term horizons. COMASO (coastal management software) intends to fill this gap, presenting a group of tools that can be applied in standalone mode, or in a sequential order. The first tool should map the coastal erosion vulnerability and risk, also including the climate change effects, defining a hierarchy of priorities where coastal defense interventions should be performed, or limiting/constraining some land uses or activities. In the locations identified as priorities, a more detailed analysis should consider the application of shoreline and cross-shore evolution models (second tool), allowing discussing intervention scenarios, in medium to long-term horizons. After the defined scenarios, the design of the intervention should be discussed, both in case of being a hard coastal structure or an artificial nourishment (third type of tools).
