Field Activity 2014-643-FA

Identifier 2014-643-FA
Purpose Measure topographic profiles of the river channel.
Location Carmel River, California, USA
Summary Topographic data were collected in the Carmel River channel successfully at the locations specified above. Topographic surveys were used to delineate channel-perpendicular transects and bathymetry within pools in river bends. Data were analyzed and quality verified by Josh Logan, and further work has been completed to merge these data with additional data collected by NOAA personnel at adjacent field sites.

High resolution topography for two pools on the Carmel River, central California, 2014 to 2019 Total Station High-resolution topographic surveys were conducted at two pools on the Carmel River between 2014 and 2019 using a survey-grade total station. The Dam Reach pool (DMPOOL) is located within the Dam Reach, approximately 450 meters downstream of the former site of the San Clemente Dam. The Sleepy Hollow pool (SHPOOL) is located within the Sleepy Hollow reach, approximately 2.25 kilometers downstream of the former site of the San Clemente Dam. Both pools were surveyed in 2014, 2015, 2016, 2017, and 2019 using a total station, in conjunction with the channel cross-section surveys also conducted as part of this study (see accompanying file within this data release for topographic survey transect data). For the 2015 survey, a kayak-mounted single-beam echosounder was also used to augment the data collected with the total station. Horizontal and vertical coordinates are provided for each point surveyed. Vertical coordinates are referenced to the NAVD88 vertical datum, in units of meters. Horizontal coordinates are referenced to the NAD83(2011) reference frame, projected in Universal Transverse Mercator (UTM) coordinates (zone 10N), in units of meters. Amy East
Topographic survey transect endpoint coordinates along the Carmel River, central California, 2013 to 2021 (ver. 2.0, March 2022) Total Station This dataset contains the easting, northing, and elevation values of the river-right and river-left transect endpoint reference benchmarks (RBM and LBM) from survey transects at 10 survey reaches along the Carmel River, central California. Topographic surveys were completed on these transects during eight summer surveys (in 2013, 2014, 2015, 2016, 2017, 2019, 2020 and 2021). See accompanying file within this data release for elevation measurements. All data were collected in NAD83 UTM10N horizontal coordinates and NAVD88 Geoid 12B vertical coordinates, in units of meters. The positions of some reference marks were selected using only horizontal reference, the elevation values for these marks are set to a no data value of "NULL" in the data file. Amy East
Topographic survey transect data along the Carmel River, central California, 2013 to 2021 (ver. 2.0, March 2022) Total Station Topographic surveys were completed during eight summer surveys (in 2013, 2014, 2015, 2016, 2017, 2019, 2020 and 2021) at 10 sites along the Carmel River, CA: Berwick (BW), Control Reach (CR), Crossroads (CRO), DeDampierre Lower (DDL), DeDampierre Upper (DDU), Dam Reach (DM), Reservoir Reach (RS), San Carlos (SC), Sleepy Hollow (SH), and Schulte Road (SR)). Topographic measurements were made at multiple locations along four to six cross-section transects per site using a total station (at sites CR, RS, DM and SH) and with an auto level and survey rod (at sites DDU, DDL, BW, SR, SC and CRO). This dataset contains the cross-sectional elevation measurements for each transect and survey year. The elevation measurement locations along each transect were located by measuring distances between corresponding endpoint coordinates, starting from river left (see accompanying file within this data release for topographic survey transect endpoint coordinates). For the transects measured with a total station (CR, RS, DM and SH), horizontal coordinates, elevation and distance from the left bank end point are provided. For the transects measured with an auto level (DDU, DDL, BW, SR, SC and CRO), only elevation and distance from left bank end point are provided (horizontal coordinates are defined as NULL for these transects). Vertical coordinates are referenced to the NAVD88 vertical datum, in units of meters. Horizontal coordinates are referenced to the NAD83(2011) reference frame, projected in Universal Transverse Mercator (UTM) coordinates (zone 10N). These data supersede grain-size data originally published in 2017 at https://doi.org/10.5066/F74M93HF. Amy East
Grain size data from the Carmel River, central California, 2013 to 2021 (ver. 2.0, March 2022) Totalstation 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. Amy East
