Modeling barrier islands and fluvial-deltas across time scales: Insights from a moving-boundary approach
There are few regions of the Earth that change more rapidly and consistently than the coastal zone. Despite this transience and its susceptibility to hazards, the coast continues to attract humans and development. Additionally, coastal deposits can hold important information about environmental changes in Earth's history, such as variations in relative sea level, sediment supply, or tectonics. Accordingly, deeper knowledge of the formative and destructive processes operating at the shore is of both scientific interest and societal importance. In this presentation, I will introduce a moving-boundary framework aimed to advance our quantitative understanding of the key processes that drive the evolution of low-lying coastal landscapes such as barrier islands, fluvial deltas, and continental shelves. I will also provide examples of how this mathematical framework can be applied at both field and laboratory scales.
