Day 3 – Thursday October 20th

Caribbean coastal dynamics, coastal development scenario’s and Caribbean coastal zone research initiatives

Morning session

The morning session will focus on an integrated approach looking at coastal configurations and morphodynamic processes and the development of scenario’s for coastal development in various settings. Two topics will be covered in more detail. These are the impacts of extreme wave events (tsunami and hurricane induced) on coastal configurations and coastal morphology and sedimentation patterns. Secondly we will explore sedimentation in coastal zones and the interaction between natural sedimentation processes and transport and human induced sediment transport. The first lecture Impact, Frequency, and Regional Aspects of Extreme Events in the Caribbean’ will assess the frequency of extreme events. The following lecture High-Resolution Records of Natural and Anthropogenic-induced Sediment Deliveries to Coastal Environments of the Virgin Islands’ will assess the human aspects of sediment transport. The final two lectures Causes, Impact, and Mitigation of Coastal Erosion in the Caribbean, with emphasis on the Yucatán Peninsula’ and ‘Morphodynamics of Caribbean Coastal Zones along the Margin of the South American Continent’ will analyze the implications for coastal erosion and development in two different tectonic settings.

Afternoon session

The afternoon session is completely dedicated to future scenario’s for the development of Caribbean Coastal areas. This is done from the perspective of the implications of climate change, sea level rise and the threat of increasing coastal erosion in large areas of the Caribbean region. In this session we will explore the gaps in current knowledge to inform strategies to prevent erosion and mitigate impacts. In addition we will look at the development and application of new strategies for coastal defense. This include concepts such as ‘ecological engineering’ and the use of hydrodynamic/ morphodynamic modelling of currents and sedimentation processes in threatened coastal areas. As an example of important knowledge gaps the lecture ‘A 2060 Climate Change Scenario for the Greater Everglades’ will present overview of the well studied Everglades area in Florida. This will raise the question: A new paradigm needed? The following lecture ‘Nature-based Flood Defense Scenario’s for the Caribbean’ explores the future role of ecology in coastal defense. This session will conclude with the lecture on ‘modelling Caribbean Coastal Zone Morphodynamics’ with a particular focus on the role of coastal lagoonal systems in coastal defense scenario’s.

The concluding afternoon session will focus on re-capping the most important conclusions of the working conference and to discuss the direction of a proposed ‘Caribbean Joint Coastal Research Initiative’. It is envisioned that this discussion will result in the identification of important regional themes and ‘hotspots’ and help prioritize research topics within the context of societal needs. This can form the basis for a position paper on regional research priorities and proposed thematic topics that are recommended for future discussions to determine specific research needs and partnerships.

The ensuing discussion should give a, hopefully, positive answer to the need for and provide direction on how to shape future joint Caribbean Coastal Zone Research and ensure informed policy making and responsible coastal development.

The titles of the lectures are provisional.
