Abstract
We develop a refined sand budget for the Eureka Littoral Cell (ELC), along California’s North Coast, that reflects time-dependent changes in fluvial sediment yields, fluvial sand extraction, Humboldt Bay dredging, and relative sea-level rise; and incorporates comprehensive estimates of shoreline change (erosion and storage), inner-shelf storage, shoreline and estuary sand losses from RSL rise, and ultimate dune growth (storage). We also seek to: 1) quantify uncertainty in our fluvial sediment flux and sand budget estimates, 2) examine the implications of long-term trends in fluvial sediment loading estimated via static vs. dynamic rating curves, and 3) elucidate different sand pathways in the ELC.
