WebJun 9, 2024 · The U.S. Geological Survey (USGS) does quite a lot of work across the country measuring how much sediment is transported by streams. To do this, both the amount of water flowing past a site (streamflow or flow) and the amount of sediment in that water (sediment concentration) must be measured. Webobjectives of this study are to: 1) compare the sediment ﬂuxes from the two main local tributaries to the tidal sediment ﬂux measured at the bayward margin ofthe reach (Dumbarton), 2)computea sediment budget for this reach of SFB, and 3) determine if this reach serves as a source or sink of sediment to greater SFB.
