CESD Group

Mission

The Coastal Ecosystem Dynamics (CESD) specialization brings together faculty with expertise in coastal hydrodynamics, geo-mechanics, and ecology. The goal of the group is to advance fundamental science, provide solutions for resilient coastal communities, and train the next generation of scientists and engineers to succeed in academic and non-academic careers.
With nearly 40% of the world’s population lives within 100 kilometers of the coast, understanding the dynamics of coastal ecosystems is critical to ensure the resilience of human and natural coastal communities and requires multi-disciplinary research and solutions. Coastal ecosystems sit at the interface between marine and terrestrial environments, and their structure and stability are driven by complex interactions among hydrodynamic forces, geotechnical properties of natural and man-made substrates, and organisms that biogenically build coastal reefs and wetlands.
Students trained in the new PhD specialization will be prepared to pursue academic and industry careers in the fields of coastal, environmental, and geotechnical engineering, as well as, in the future, other engineering disciplines such as mechanics, structures, ecology, environmental science, geology, natural resource management and coastal resilience.

Katie Glodzik

Adviser: Dr. Kaplan

PhD student Katie Glodzik is studying how saltwater intrusion from SLR and decreased river flow are combining to threaten coastal ecosystems, particularly those modified by development. Her study looks at drivers and impacts of saltwater intrusion and altered hydrology in the coastal wetlands of Florida’s Big Bend region to meet three primary objectives: 1) to determine long-term trends and drivers of river discharge; 2) to evaluate the effect of coastal roads on salt marsh hydrology and ecology; and 3) to use physical and hydrological variables to predict coastal forest die-off. Preliminary results show that roads consistently decrease invertebrate densities in tidally-restricted marshes, while impacts to salinity and vegetation vary by road.

 

Amy Langston

Adviser: Dr. Kaplan

PhD student Amy Langston is investigating how SLR and a warming climate are driving reassembly trajectories of coastal vegetation. Her data on tree and understory vegetation in freshwater forest islands extend a 20-year dataset and reveal long-term trends of forest decline and marsh conversion. Amy’s field experiments on mangrove seedling success in relict freshwater islands show that, while climate change provides favorable conditions for mangrove establishment, crab predation and insect herbivory are strong top-down controls on mangrove encroachment into new areas.
