We use natural records of floods preserved in the river landscape to determine the age and size of individual flood events. Often these floods precede the instrumented and historical records, which extend our flood histories and provide new insights on extreme floods (>100-yr recurrence intervals). We use these data to assess flood risk and understand drivers of non-stationary flood behavior.

We are interested in how floods shape the fluvial landscape. We are currently studying how the interaction of local and regional water on the floodplain impacts channel-floodplain connectivity and flood sedimentation. This conceptual model of overbank spillage would provide critical insights into floodplain evolution, nutrient cycling, and potential bias in paleoflood records.
