San Lorenzo River watershed on central California coast alongside a sediment rating curve

Figure shows (a) San Lorenzo River watershed, central California coast, which empties into Monterey Bay. Fluvial sediment sampling location is indicated just upstream of river mouth. Locations of rain gages are indicated (National Oceanic and Atmospheric Administration, 2025). (b) Sediment rating curve generated from log-transformed discharge data (Q, m³/s) and suspended-sediment concentrations (SSC, mg/L). As essentially all of the sediment is siliciclastic, density of 2,650 kg/m³ can be assumed. OLS, ordinary least squares regression. From the study River Floods Under Wetter Antecedent Conditions Deliver Coarser Sediment to the Coast.
