Understanding and quantifying the effect of variability in surface processes and the sedimentary record is vital for both predicting future landscape change and for deciphering landscape response to paleo-environmental conditions. These are of paramount importance for sustainable management of landscapes during a time of climate change and anthropogenic interference.
My research aims are centered around answering two broad questions: (a) How do modern geomorphic processes, which show variability over a wide range of spatiotemporal scales, interact and manifest themselves in landscape form and function?; (b) What is the depositional signature of these processes in the sedimentary record? To address these research questions, I use an interdisciplinary, integrated approach that combines an in-depth understanding of modern geomorphic processes and ancient sedimentary deposits with the hydrodynamics of sediment transport and loose-boundary hydraulics typically undertaken within a civil engineering context. I approach these problems using a suite of laboratory experiments, sediment-transport theory, targeted fieldwork, and field-data compilation.
