Modeling Morphodynamics in Estuaries and Deltas and their Feedbacks with Ecosystem Engineering
Biogeomorphic feedbacks between geomorphology and ecosystem engineering species, such as vegetation and benthic organisms, shape the evolution of our rivers and coastlines under climatic and anthropogenic drivers. Understanding how geomorphology changes over space and time is crucial for mitigating flood risk and sustaining biodiversity. To quantify how ecosystem engineering drives geomorphology and species patterns, I will present and show results of a dynamic eco-morphodynamic model that couples ecological and physical processes in estuaries and deltas. The models showcase the relevance of species-specific traits for saltmarsh growth and for their capacity to deposit fine sediments and build land. In addition, I will present comparisons of those model predictions with data from the Mississippi River Delta.
Dr. Muriel Brückner is an Assistant Professor at the Department of Civil and Environmental Engineering at LSU. She holds a BS and MS degree in Environmental Engineering from the Technical University of Braunschweig in Germany and a PhD in Biogeomorphology from Utrecht University, the Netherlands. As a postdoctoral researcher at the University of Exeter, UK, and UT Austin, she studied fluvial dynamics in the Amazon River Basin and accretion in the Mississippi River Delta. She is interested in understanding how organisms and geomorphology interact across environments, and how they are impacted by climate change and human influence. In her research she develops process-based models to represent dynamic coupling of physical and biological processes.
