Rivers are conduits for transport of fresh water, sediment and nutrients throughout the landscape. Humans manage rivers for water supply, power generation, flood control and navigation. These needs often conflict with ecological functions of rivers, such fish migration. My research focuses on understanding how rivers respond to changes, ranging from long-term variations in tectonics or climate to short-term shifts in dam function or land use. I link measurements of channel morphology from high-resolution airborne lidar digital elevation models with field-based measurements of stream processes.
