I am excited to present collaborative work with Rice Sedimentology and Rose Palermo at AGU 2018! During sea-level rise, coastal barriers (islands and peninsulas) are thought to respond by retreating landward. However, bay accommodation may (1) vary in bay depth (ΔDb) (2) be subjected to variation in rates of RSLR (relative sea-level rise, ΔRSLR), or (3) both bay depth and rates of RSLR may vary (ΔDb & ΔRSLR). Variable bay morphology may drive alongshore changes in retreat rate, generating shoreline curvature, and modifying longshore transport. The videos below are a supplement for our 2018 AGU poster, which is available as a PDF.

Many thanks are owed to the CoRE group (Especially Zane Jobe) at the Department of Geology and Geological Engineering at the Colorado School of Mines for inviting me to give a departmental seminar in their Van Tuyl lecture series. For this seminar, we will explore the response of the expansive system of barrier islands and peninsulas along the Texas coast to a wide survey of sea-level rise rates and barrier overwash configurations.
As always, please feel free to download a PDF of the presentation!
