| Purpose | 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. | ||||||||
| Location | San Lorenzo River, Santa Cruz, CA | ||||||||
| Summary | 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. | ||||||||
| Info derived | suspended sediment/sediment transport in river | ||||||||
| Comments | Data spanned the wettest water-year on record for the San Lorenzo watershed. | ||||||||

| Polycyclic aromatic hydrocarbons (PAHs) in the San Lorenzo River, Santa Cruz, California, USA, from 2015 to 2016 | samples | Polycyclic aromatic hydrocarbons (PAHs) are reported for water samples collected from the San Lorenzo River water during the rainy seasons from 2015 to 2016. Samples were collected during 2-, 5- and close to 10 year flood events. | Pamela L Swarzenski |
| Suspended-sediment concentration and grain size in the San Lorenzo River, coastal California | samples | Water samples were collected from the San Lorenzo River, Santa Cruz, California, and analyzed for suspended-sediment concentration and sand break (proportion of sand vs. silt-plus-clay) at the U.S. Geological Survey (USGS) laboratory in Santa Cruz, California. | Amy East |
| Suspended sediment concentration (SSC) from 2008 to 2019 | samples | 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. | Pamela L Swarzenski |
