Collect suspended-sediment samples from a bridge-mounted sampling station on the San Lorenzo River (pedestrian bridge between Water St and Soquel Ave), opposite the downtown Trader Joe's. We intend to sample every hour or two (more often on the highest flows) throughout rainfall events as part of a multi year study of how antecedent conditions affect coastal watershed sediment yield in this area.
San Lorenzo River, Santa Cruz, CA
Collected 384 water samples between water-years 2009 and 2024 that were processed at CA Water Science Center field station in Santa Cruz for suspended-sediment concentration and sand break.
suspended sediment/sediment transport in river
Data spanned the wettest water-year on record for the San Lorenzo watershed.
Suspended-sediment concentrations are reported in mg/L for water samples collected from the San Lorenzo River during the rainy seasons from 2008 to 2019. Samples were collected during 2-, 5- and 10-year flood events.
