Selection of Appropriate Coastal Protection Strategies for Caribbean Coastlines (2016)Jamel Banton, Philip Warner, David Smith, Veronique Morin

The coastlines of the Caribbean are unique in many ways. Their warm waters and sandy beaches attract millions of visitors to their shores and these attributes provide an essential economic opportunity. Coastal hazards affecting the region include hurricanes, tsunami, and coastal erosion. For islands with mountainous interiors, development is often concentrated along the coastlines. This paper draws on more than 20 years of experience designing and evaluating coastal protection schemes in the region, and the related issues, constraints and opportunities are discussed. Projects in The Bahamas, St. Vincent, Guyana, Jamaica and Barbados are cited and the reasons for their appropriateness to the region and specific locations are highlighted. The paper highlights the importance of multi-criteria analyses for coastal project selection and the need for funding agencies to insist on a thorough evaluation of options at the design stage.

Caribbean storm Surge Mapping – An overview towards regional guidelines (2013)Jamel Banton, Danielle D. Dowding

Hurricane waves and surges can have a crippling effect on economic growth in Caribbean island states. In reducing the vulnerability to these disasters, exposed areas to storm surge must first be identified and inundation levels predicted. Various methods and models have been applied to estimate storm surge at sub-regional scales and for coastal sites and towns. The approach used to filter and utilise the hurricane data, and the statistical methods employed to develop final values are often different. The territories through different funding agencies have sponsored several projects to map storm surge, but there has not been a single unified project or approach. This paper puts into perspective the requirements for storm surge evaluation, outlines the varying approaches relevant for the region and re-emphasises the need for an established set of regional guidelines.

Long Term Variability of Hurricane Trends and A Monte Carlo Approach To Design (2002)David A.Y Smith, Philip S. Warner, Jamel D. Banton

Whilst beach erosion in Negril over the past 5-10 years has gained significant media attention, the calculation of the true rates of erosion that could be used in the design of rehabilitation works requires careful analysis. Ideally, a long-term database of regular beach profile measurements would be available and could be analysed to separate beach response to storms, seasonal fluctuations and long-term trends. In the absence of this long-term data set, two main sources of beach width data have been examined. The first is aerial and satellite images from 1968, 1980, 1991, and 2003, and the second is a series of beach profile measurements taken between 2000 and 2003. In addition, a series of detailed beach profile measurements were made in 2006. This paper looks at the available sources of beach width data and determines related erosion rates for Long Bay and Bloody Bay.

Medium and Long Term Shoreline Erosion at Negril – Abstract (2009)David A. Y. Smith, Veronique Morin

An examination has been made of multi-decadal and longer-term trends in hurricane frequency and intensity in the North Atlantic and Caribbean Basins. The investigation points to an increasing occurrence of hurricanes, which may also be more intense. There appears to be a strong link between global warming impacts and these findings. This paper presents a recommended methodology for incorporating these anticipated changes into the development of a design wave climate for coastal infrastructure in the Caribbean.

Evaluation Of A Mitigation Strategy To Combat Beach Erosion At Negril (2009)Philip S. Warner, Elisabeth A. Mondon

Over the past 5-10 years the problem of coastal erosion along the beaches of Negril has received much media exposure. There are believed to be several factors that have contributed to the problem, such as a series of damaging hurricanes and severe swell events, as well as the construction of tourism-based infrastructure close to, or at, the waters edge, poor water quality, degrading seagrass beds and declining coral reef health. The beach is typically sheltered from the Trade Winds, but when it is exposed to passing storms, the beach exhibits a noticeable response. Extensive investigative work on the Negril Beach erosion problem has been carried out for the Negril Coral Reef Preservation Society in a recent Preliminary Engineering study entitled “Beach Restoration Works at Negril”. Part of the work applied detailed coastal engineering analyses to understand the prevailing coastal processes and develop remedial engineering solutions that address the problem of beach erosion along the shoreline.

MSc Thesis of Jamel Banton- Parametric Models And Methods of Hindcast Analysis For Hurricane Waves (2002)David A. Y. Smith, Veronique Morin

Scientists and Engineers around the world have naturally developed a fascination with cyclones (called Hurricanes in the North Atlantic Basin). With this fascination, we have developed a range of prediction models for cyclone-generated winds and waves. In addition, we have adapted statistical procedures to analyze the probable wind and wave conditions for different time intervals. These conditions are vital in determining the potential shoreline impacts such as storm surge levels and coastline erosion. There are several prediction models and similarly several commonly used statistical methods. Unfortunately, these models and methods often give varying results and as such it becomes unclear as to which are most suitable for application to a particular situation. In addition, there is only a handful of measured data to inter-compare and calibrate these models.
