We’re pleased to announce the release of our findings and recommendations from DredgeFest California, which can be downloaded here. They delineate key principles that the Dredge Research Collaborative believes should guide the design, planning, and management of sediment in California’s Bay-Delta.

Sediment is an increasingly scarce resource which is critical to the health of this estuary — and many others like it around the world — yet sediment is too often undervalued, understudied, and underdesigned. Moreover, the Bay-Delta is in a period of rapid change, propelled by local forces like development and global forces like climate change, which requires new thinking to meet new challenges.

The report describes the current state of affairs in the Bay-Delta with a summary of scientific research and maps, diagrams, and drawings that concisely visualize sediment in geographic context. Eleven key recommendations then outline the contours of new thinking that can meet the sedimentary challenges that the Bay-Delta faces and emphasize directions for additional research.

Along with the release of the report, the Dredge Research Collaborative has partnered with Landscape Metrics to create “The Hidden Sediment Reserve”, an interactive web visualization that illustrates the sediment needs of Bay-Delta wetlands and allows users to explore the sediment volumes trapped within the Bay-Delta watershed’s many reservoirs.

The principles articulated in the report are based on the work of DredgeFest California, a week-long event held in the Bay Area in July 2016.
