Modeling Forced and Self-Organized Morphodynamic Responses of Coastal Systems
Speaker: Maitane Olabarrieta, Assistant Professor, University of Florida-Gainesville
Coastal ecosystems provide a suite of valuable benefits on which humans depend. Examples of ecosystem services associated with coastal areas include reducing the impact of storms, providing nursery for fish and other species, water filtration, from others. These ecosystem services are dependent on the landscape or the coastal morphology. Due to human impacts, sea level rise and changing climate conditions, most of the coastal areas around the world are experiencing morphological changes and a reduction of the associated ecosystem services. The coastal change, together with the increase of population of the coastal areas, has resulted in an increase of the vulnerability of many coastal communities. There is an urgent need to understand the response of the coastal landscape to changing forcing conditions, in order to develop predictive tools and propose strategies to reduce the vulnerability of coastal communities.
This seminar will focus on the different types of responses of the coastal morphology to external forces. Coupled- process based numerical models are robust tools that can be used to gain a better understanding of forced and self-organized responses. As examples of forced and self-organized systems respectively Dr. Olabarrieta will discuss the ongoing modeling efforts of Hurricane Matthew (2016) along the east coast of Florida and the effects of baroclinicity on long-term evolution of idealized estuaries.
Maitane Olabarrieta is currently an Assistant Professor at the Civil and Coastal Engineering department at the University of Florida. She received her Ph.D. from the University of Cantabria (Spain) in 2006. Her research interests cover diverse oceanographic and long-term morphodynamic evolution problems that affect our coasts. By combining both measurement analysis and numerical modeling techniques, she and her students study processes with a wide variety of spatial and temporal scales, including momentum exchange processes during hurricanes and extreme storms, the generation mechanisms of meteotsunamis, short-term estuarine transport processes, and the long-term evolution of tidal networks and inlets. One of her main goals is to improve numerical models used to predict coastal change, erosion and flooding. During her research career has collaborated with several research groups from Europe, the United States, New Zealand, China, and Australia. In 2015 Maitane received the NSF Career Development Award, that has provided her the unique opportunity of analyzing the morphodynamic evolution of mix-energy inlet systems.
