Description:

Abstract:

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.

Purpose:

These data were collected and analyzed to determine possible changes in suspended-sediment concentrations in the San Lorenzo River during the wet seasons from 2008 to 2019.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Blanks were run with every batch of 20 and a reference sample of known concentrations was run monthly. Data were calculated as percentages based on the amount in grams of that size fraction in relation to the total suspended sediment sample.

Logical_Consistency_Report: No formal logical accuracy tests were conducted.
Completeness_Report:

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. The horizontal accuracy is based on a hand-held Garmin GPS with a stated manufacturers accuracy of +/- 3.0 m.

Process_Step:

Process_Description:

River water samples were collected using a US D-95 water sampler with a 1L Nalgene bottle attached, which was lowered throughout the water column by hand from a bridge-box platform beneath a pedestrian bridge in Santa Cruz, California. After 14 days of settling time, excess water and organic matter were removed using wet suction from a vacuum pump; the sand fraction was then separated from silt and clay by filtration through a 0.063-mm sieve. Each fraction (sand and silt-plus-clay) was dried in a crucible in a 103-degree Celsius oven, and then weighed. The supernatant fraction was not analyzed. Concentration results are reported in milligrams per liter (mg/L).
