rivers, their transformations by humans, their resilience, and their active restoration

300 Wurster Hall

My research and teaching focuses on rivers, their transformations by humans, their resilience and their active restoration. I work on a variety of rivers, including salmon-bearing rivers and Mediterranean-climate rivers, and effects of human alterations like dams, dredging, and gravel mining. In my work, I emphasize understanding of river processes (physical and ecological) and history as a basis for restoration strategy, the need to learn from each restoration project, and the need for scientific rigor when approaching restoration. My current research interests include (1) analysis of changes in land use, sediment delivery, and channel form since the 19th C in southeastern France, the Sacramento-San Joaquin River basin in California, and other Mediterranean-climate regions, (2) effects of dams on physical and ecological processes in rivers, and strategies for process-based ecosystem restoration, (3) sediment management in aging reservoirs, and (4) geomorphic/ecological post-project assessment of river restoration projects, and (5) land-use planning in flood-prone regions of California and Mississippi deltas, and integrating geomorphic insights into restoration strategies for these regions.
