Cultivating Water Resources on River Deltas

Austin is a graduate student in geology working in Prof. Michael Lamb’s group. He earned his bachelor’s degree in geophysics at UCLA, where he conducted research in geophysical fluid dynamics and tectonic geomorphology. At Caltech, Austin studies the mechanics of river deltas using a combination of theory, laboratory experiments, and remote sensing techniques. His research focuses on the natural tendency of depositional rivers to catastrophically change course, and how the frequency and location of these events are influenced by land subsidence and flood variability. Predicting patterns of channel-switching is crucial for sustainable water resource management on densely populated river deltas. A better understanding of how rivers naturally distribute water and sediment across floodplains and wetlands will help us to recognize the long-term consequences of water infrastructure such as dams and levees, and to revise management solutions like engineered diversions.
