Bay sediment budget: Sediment accounting 101
January 1, 2005
- Comparison of a budget developed for 1955-1990 with a budget developed for 1995- 2002 showed decreasing sediment inflow and increased amounts leaving the Bay to upland disposal and sand mining, resulting in an increased rate of erosion of sediment from the Bay floor
- Finding a way to shift disposal from the Ocean back to the Bay could provide sediment for restoration projects and decrease dredging costs
- Increased erosion of the Bay is mobilizing legacy contaminants from the sediment bed
- Restoration projects could increase erosion and mobilization of legacy contaminants
- Sand mining, ignored in previous budgets, removes almost twice as much sediment from the Bay as dredging
