Grain size data from the Carmel River, central California, 2013 to 2021 (ver. 2.0, March 2022)
Pebble-count data were collected during summer surveys (2013, 2015, 2016, 2017, 2018, 2019, 2020, and 2021) at ten sites along the Carmel River, California. Grain-size measurements were made at four to six transects per site using a 0.5 by 0.5 m sampling frame, with approximately 100 sediment-particle counts per transect. Each transect was defined by coordinates on the left and right sides of the river, and sediment grain sizes were measured at five equally spaced locations within the bankfull channel on the transect defined by those endpoint coordinates (see accompanying file within this data release for transect endpoint coordinates). The grain-size data file reports spatial information as being the midpoint of the transect.
Grain-size diameters were measured using a gravelometer. We report grain-size values to the next size class up in this spreadsheet, that is, the size gradation that the sediment grain passed through on the gravelometer frame, with the data being analogous to the percent passing in sieve analyses.
These data supersede grain-size data originally published in 2017 at https://doi.org/10.5066/F74M93HF.
