Brett Milligan is professor of landscape architecture at the University of California, Davis, where he directs the Metamorphic Landscapes Lab. He is also a co-founding member of the Dredge Research Collaborative. In this talk, Brett will discuss his forthcoming co-authored book: Silt, Sand, Slurry: Dredging Sediment and the Worlds we are Making, which is an investigation into where, why, and how sediment is vital to the future of America’s coasts, estuaries, and rivers. Sediment is approached as unseen infrastructure that shapes and enables modern life. Human actions now move more sediment annually than ‘natural’ geologic processes — yet this global reshaping of the earth’s surface is rarely-discussed and poorly-understood. Through image and text, the book explores the many limitations of current sediment management practices, and in response, delineates an approach to designing with sediment that is more adaptive, healthy, and equitable.
