Description:
Abstract:
Corte Madera Marsh, located in northern San Francisco Bay, California, is experiencing shoreline erosion. Determining whether the eroded sediment is exported to the bay or imported via tidal channels and deposited on the marsh platform is critical to understanding the long-term response of the marsh to wave attack and sea-level rise. Quantifying water-column sediment flux helps to characterize the role of tidal channels in this process, and water discharge is a key component of sediment flux. Tidal creek discharge was measured repeatedly over diurnal tidal cycles in a tidal channel located in the central, Muzzi marsh region of Corte Madera marsh, California during the summer of 2022 and during the winter of 2023. These transect data were collected using a downward-looking Teledyne RDI RiverPro 1200-kilohertz acoustic Doppler current profiler (ADCP) from a moving boat.
Purpose:
The discharge measurements were used in the development of an index-velocity relationship between flow velocity measured at a single location within the channel and the channel-average velocity. This relationship enables the computation of a time-series of total channel discharge from long-term measurements of current velocity at a single location within the channel. These data were collected as part of a study with the goal to produce information useful for prioritizing marsh restoration sites, assessing restoration actions, and understanding mechanisms of sediment delivery to marshes. These data are intended for researchers, students, policy makers, and the general public.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
No formal attribute accuracy tests were conducted. Data were processed using QRev. QRev uses a color-coded scheme in its graphical user interface to indicate potential areas of concern (e.g., percent change in discharge magnitude between consecutive transects). Because these measurements were made in tidal systems with highly variable bathymetry, these changes are expected and many of the yellow- and red-colored regions in QRev are to be expected. ADCP data were collected in 0.06 m depth bins. Variation in tidal elevation resulted in variation the ability to measure the entire width of the tidal channel. During the highest tides, the marsh was fully inundated and there was no defined edge to the channel. For this reason, all data has been retained and must be handled with care.
Logical_Consistency_Report:
Data fall within expected ranges. Data were processed using QRev and reviewed by staff experienced in ADCP discharge measurements. All data were collected using the same instrument, computer, and moving-boat platform.
Completeness_Report:
Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the metadata for each part of this data release carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
GPS locations were collected using a Hemisphere A631 GNSS Smart Antenna. The GPS antenna was located directly above the ADCP during data collection. Based on manufacturer specifications, the locations are assumed to be accurate within 2 m Circular Error Probable (CEP).
Vertical_Positional_Accuracy:

Process_Step:
Process_Description:
Discharge data were collected using a boat-mounted Teledyne RDI RiverPro 1200 kHz acoustic Doppler current profiler (ADCP), in one tidal channel during Spring tides in the summer of 2022 and winter of 2023, at one location within a tidal creek in Corte Madera marsh. The boat repeatedly traversed each channel from one bank to the other, collecting data during each transect crossing. The dates and times of the transect measurements were chosen to cover as much of a full diurnal tidal cycle as possible, subject to logistical and safety constraints. ADCP data were recorded and initially reviewed using WinRiver II version 2.23. WinRiver II is available at http://www.teledynemarine.com/support. The raw data were recorded in .mmt and .pd0 files, which are the native file formats of WinRiver II.
Process_Date: 20230120
Process_Step:
Process_Description:
Data were post-processed using QRev version 4.31 or 4.33, a program developed by the USGS Office of Surface Water to compute moving-boat ADCP discharge. QRev automates data-quality checks, data filtering, extrapolation methods, and invalid-data-handling steps, and provides estimates of uncertainty to help guide the user. QRev is available at https://hydroacoustics.usgs.gov/movingboat/QRev.shtml.
Process_Date: 20240507

Process_Description:
QRev file naming convention consists of YYYYMMDD_HHMMSS_VER_BT_QRev where, starting with the date and time at start of the transect, VER is the QRev software version 4.31 or 4.33, and BT indicates the position within each transect was determined using bottom tracking from the initial GPS position.

Overview_Description:
Entity_and_Attribute_Overview:
This dataset consists of discharge measurements collected using a Teledyne RD Instruments RiverPro ADCP (Teledyne RD Instruments, 2024). All data were collected with Teledyne RD Instruments WinRiver II version 2.23 (Teledyne RD Instruments, 2016) and processed with QRev (Mueller, 2016). Due to the complexity of an ADCP data file and the various algorithms applied to compute the streamflow from ADCP data, these data are most useful in either 1) their original raw data format which can be opened and processed in either WinRiver II or QRev or 2) their processed format which can be opened and processed by QRev or opened by Matlab or any software that can read Matlab formatted files. Both WinRiver II and QRev are distributed free. This dataset is in the form of a zip file, NBM_discharge.zip. The data are divided into folders based on location and acquisition time, and further divided by software association. The top-level folder naming convention consists of Season_X, where Season is specified as Summer or Winter, the survey index is appended. Each of these folders contains two subfolders: QRev_Files and WinRiver_II_Files. The WinRiver II files consist of: 1. .mmt file: XML configuration file used by WinRiver II for setup, specific measurement data entry, and filenames of the raw transect data files (pd0) 2. .pd0 files: raw binary data collected by WinRiver II. The format for these files is defined in Teledyne RD Instruments (2013). The QRev files consist of: 1. .mat files: saved data processed by QRev. These files can be opened and processed by QRev or loaded into Matlab or software that can read Matlab formatted files. The variable definitions are documented in Mueller (2016). 2. .xml: summaries of the data processed by QRev. The variable definitions are documented in Mueller (2016). Refer to the README_NBM_Discharge-File-Explanation.txt file in this directory for further information.
