“…The Caribbean SIDS of Saint Lucia ( Figure S1) has a mountainous landscape that is characterized by steep slopes cut by fast-flowing water drainage networks, confined low-lying coastal areas, and pocket beaches (UNCTAD, 2017). Coastal lowlands in Saint Lucia have a high concentration of human settlements, hotels, seaports, airport, and transportation infrastructure that connect major communities and coasts on the Island (M. Mycoo, 2011). These highly developed low-lying areas, however, are vulnerable to tropical storms and the subsequent compound flood events that commonly impact the Island from September to November.…”

The passage of a tropical storm, as the main driver of storm surge and high waves in many coastal regions, can also generate heavy rainfall and cause river overflow. The resulting combination of riverine, pluvial, and coastal flood hazard can result in catastrophic losses particularly in densely populated coastal environments. In this study, we characterize compound flooding caused by Tropical Storm Matthew and assess the significance and associated uncertainties of multiple contributing factors over a data-scarce coastal region. A hydrological model combined with a simplified two-dimensional hydrodynamic model are set up and validated to investigate the compounding effects of storm tide, wave runup, rainfall, and river overflow at the southern coast of Saint Lucia in the Caribbean Sea. Pléiades-1 and Sentinel-1 satellite imageries are used to determine the flood-impacted areas. The analyses are performed based on deterministic and probabilistic approaches and the effects of uncertain boundary conditions and model parameters are investigated. Results show that the individual analysis of flood hazards, in isolation, can lead to substantial underestimation of flood risks. Heavy rainfall and wave runup are the most significant contributors to compound flooding in Saint Lucia. In addition, the interactions between seawater and streamflow can exacerbate riverine flood hazards particularly upstream of the river mouth. Communities in western Vieux Fort, and the Hewanorra International Airport, have high exposure to compound flooding, which is projected to intensify under climate change.

“…While islands like Jamaica are experiencing drought, and other parts of the region such as Honduras have experienced coastal flooding (Wrathall et al, 2014), the phenomenon of inland flooding due to changes in the hydrological cycle is less well researched. Key climatic concerns in the region have mainly focused on increased drought with impacts on fresh-water resources (Cashman et al, 2010;Mycoo, 2007) and increased hurricane intensity and frequency (Mycoo, 2011). According to the Intergovernmental Panel on Climate Change, ''Rainfall records averaged over the Caribbean region for 100 years show a consistent 0.18 mm yr À1 reduction in rainfall, a trend that is projected to continue (Jury and Winter, 2010)" (IPCC, 2014, Ch.…”

“…Donors such as the US Agency for International Development (USAID) have funded the construction of hurricaneresistant housing, hospitals, schools, and shelters. In some countries, the need to recover quickly in the aftermath of hurricanes has resulted in the quick erection of buildings without regard to hurricane resistant building standards (Mycoo, 2011b). Another good practice in adopting accommodation as an adaptation strategy is elevating infrastructure.…”

“…The main lesson drawn from these projects is that strong enforcement capacity in city planning agencies is necessary to ensure household compliance in adopting the building code for hurricane-resistant housing. In Castries and Anse La Raye, Saint Lucia households have at times rebuilt hastily in the aftermath of hurricanes without adhering to the hurricane-resistant designs and coastal setbacks (Mycoo, 2011b).…”

August 11, 2016 Regional Responses of Caribbean Agencies 13 LIST Of phOTOS Coastal cities of Caribbean and Pacific Small Island DevelopingStates (SIDS) are highly vulnerable and will be among the earliest and most affected by climate change in the coming decades. Approximately 29 million people reside in Caribbean and Pacific SIDS, 4.2 million of which reside in low-elevation coastal zones (LECZs) located less than 10 meters above the sea level. The cost of damage to critical infrastructure that supports human settlements along the coast that results from rising sea levels will be a financial burden to many SIDS. By 2100, the cost of rising sea levels as a percentage of GDP will be highest among SIDS and enormous relative to the size of their economies. Impacts could include a decline in national output, inflation, increasing debt, revenue loss, and employment decline. Adapting and improving the resilience of cities in coastal zones of SIDS, especially those experiencing rapid urbanisation, remains critical.The unique patterns of urban growth in SIDS increase their vulnerability to climate change. This model includes: SIDS can seize opportunities to minimise the impact of greenhouse gas (GHG) emissions, as well as rising sea levels and natural hazards on their ur...
