Curt Storlazzi, PhD

My interests span the coastal zone, from seacliff erosional processes to sediment dynamics in the shallow coastal ocean. My research focuses on the quantitative study of hydrodynamics, sediment transport, and geomorphology in coastal and marine environments.

Research Topics

Coral reef morphology, hydrodynamics, and sediment, nutrient, contaminant, and larval transport

The role of coral reefs and other coastal ecosystems in coastal hazard risk reduction

The interplay between geologic structure, climatic fluctuations, and coastal processes

High-resolution oceanographic instrumentation and coastal mapping techniques

The influence of physical processes on coral reef ecosystems

Many tropical coastal environments have been impacted by infrastructure development, nutrient and contaminant delivery, and natural and human-induced sedimentation. The high geomorphic and hydrodynamic complexity both within and between coral reefs, in conjunction with past technical restrictions, has limited our understanding of the nature of flow and the resulting flux of physical, chemical, and biologic material in these ecosystems. Understanding the physical controls on the timing and magnitude of flow and sediment, larvae, nutrient, and contaminant transport, along with their impact on seafloor geomorphology, stability, and sedimentation in these refugia are essential to assessing modern anthropogenic impacts (climate change, etc.) on these ecosystems and help guide how restoration can increase the resiliency of coral reef-lined coastal communities.

The influence of climate change and sea-level rise on coral reef-lined coasts

Observations show that sea level is rising and recent projections indicate sea level will exceed 1.0 m, and may reach 2.0 m, above 2000 levels by the end of the 21st century. The amount of land and water available for human habitation, water and food sources, and ecosystems along coral reef-lined coasts is limited and vulnerable to wave-driven flooding during storms. Rising sea levels will further exacerbate the impacts of storms on coral reef-lined coasts by reducing wave breaking (and thus energy dissipation) over reefs and result in greater wave energy impacting the shoreline, causing increased flooding and changes to the coast such as erosion. Understanding the physical controls on the timing and magnitude of flooding, along with their impact on coastal geomorphology, are essential to assessing impacts on, and the future sustainability of, coastal infrastructure, agriculture, freshwater availability, and ecosystems.
