The Special Issue Management Strategies for Coastal Erosion Processes (MSforCEP) presents an international collection of papers related to the implementation of various management strategies for coastal erosion under specific objectives:

      • Identification of significant coastal erosion issues.
      • Understanding of the underlying coastal processes contributing to erosion problems.
      • Development and evaluation of strategies for the adequate coastal erosion management.
      • Facilitation of community input on coastal erosion issues.
      • Assistance in coastal planning for the delivery of optimal erosion management options.

The SI objective is to make a clear and explicit link between fundamental concepts and the improvement of coastal erosion management practice. To reach this goal, papers presented in this special issue are grouped into four main topics:

      • Policies.
      • Management Practices.
      • Methodological Approaches.
      • New Alternatives in the Coastal Erosion Management.

The first paper “The Management of Coastal Erosion” (Williams et al.) presents an in depth analysis of coastal erosion management theory, as well as, giving many examples of the various options available to manage erosion. To the standard trio of defend, sacrifice, and realignment strategies is added a fourth strategy: ‘intervention as to the causes.’

Under the topic ‘Policies for coastal erosion management’ two papers are presented from the USA. ‘Why coastal regulations fail’ (Neal et al.) and ‘Coastal erosion and the United States Flood Insurance Program’ (Leatherman). These papers show both the general weaknesses of regulations as well as how some specific programs have failed in part due to legal flaws, and also in part for not including projected rates of sea-level rise and erosion.

The ‘Coastal erosion management practices’ section includes papers from Italy (Pranzini), Colombia (Rangel et al.), Kuwait (Neelamani), West Africa (Ndour et al.), Argentina (Isla et al.) and the USA(Nordstrom et al.). These papers confirm that coastal erosion is a rising worldwide problem, and reflect how many management practices have not been used very successfully or have failed in their purpose. The conclusion is that under current coastal development practices and climate change conditions, smart, innovative and strong coastal erosion management plans are needed.

The ‘Methodological approaches section’ includes detailed case studies from Bulgaria (Stanchev et al.), Chile (Martinez et al.), Mexico (Escudero-Castillo et al.), Saint Kitts (Stancioff et al.), USA (Psuty et al.), Brazil (Bonetti et al.) and Malta (Micallef et al.). These papers include methodologies such as i) analysis of shoreline changes by satellite images, ii) beach profiling, iii) geo-indicators and iv) the Coastal Hazard Wheel: all used as tools that provide reliable data and useful information for coastal erosion management.

Lastly, the section called ‘New alternatives in the coastal erosion management’ encompasses a review article (Gracia et al.) and four case studies from Croatia (Pikelj et al.), Portugal – the Netherlands (Stronkhorst et al.), India (Ramakrishnan et al.) and West Africa (Giardino et al.). These five papers conclude that coastal erosion management using new approaches can be cost-effective and sustainable, but the success of these kinds of strategies will depend on the determination of realistic operational objectives and indicators.

The world urgently requires effective management strategies to help solve the present coastal erosion problem. The use of one strategy by itself cannot guarantee a 100% success rate; the combination of different strategies seems a promising way forward. Management strategies for coastal erosion must be included and not overlooked in any coastal planning scheme.

Within the last few years, new approaches have received much attention, but there are still many areas in research, education, and practice that must be covered. As climate change raises the risk and incidence of coastal hazards, it is imperative that all involved stakeholders continue to examine their role and participation in the coastal erosion management process.

California’s Coastal Harbors, Beach Compartments and Sand Dredging; By Gary Griggs

October 1st, 2018

Every year the dredge at the Santa Cruz Small Craft Harbor along central California’s northern Monterey Bay sucks up about 250,000 cubic yards of sand, on average, from the entrance channel and pumps it out onto Twin Lakes Beach where it continues its journey down coast. If it were put in dump trucks, it would fill about 25,000 of them, but the waves can move all that sand without any human labor, and without any noise or carbon emissions.

Newfoundland’s Sandy Beaches: A Glacial Legacy; By William J. Neal & Joseph T. Kelley

February 1st, 2018

“Newfoundland” as a coastal place does not conjure up images of sandy beaches, but rather scenes of wave-cut rocky cliffs, bird rookeries on small rock islands, sea stacks, and boulder and cobble beaches if wave deposits are present. But scattered among the latter are genuine sand beaches.
