USGS HYDRoacoustic dataset in support of the Surface Water Oceanographic Topography satellite mission (HYDRoSWOT)

Metadata Updated: May 1, 2019

HYDRoSWOT – HYDRoacoustic dataset in support of Surface Water Oceanographic Topography – is a data set that aggregates channel and flow data collected from the USGS streamgaging network and includes 200,000+ records of USGS acoustic Doppler current profiler (ADCP) discharge measurements. The data set includes a variety of fields including: mean depth, mean velocity, discharge, stage, water-surface width, maximum depth, maximum velocity, and streamgage metadata for more than 5,000 stations in the United States. The hydraulic and channel geometry data is stored in the USGS hydroacoustic Doppler current profiler tables reported in the SiteVisit field measurement database and polled from 45 individual National Water Information System (NWIS) hosts. The database tables were de-normalized into a single flat file intended for further study in various analytical software, such as a spreadsheet or data frame. Each station can possess multiple measurements, as indicated by the measurement number recorded in the q_meas_no field. An individual measurement may have multiple sub-measurements when flow occurs in multiple channels. The multiple channels are recorded in the q_meas_chan_nu field. This dataset only contains ADCP measurement data. In the event of a multiple channel measurement, where other methods were used to measure flow, only ADCP measurements will be represented.

Licence This dataset, identified as SWOT_ADCP_Dataset, has been approved for release by the U.S. Geological Survey (USGS). Although this dataset has been subjected to rigorous review and is substantially complete, the USGS reserves the right to revise the data pursuant to further analysis and review. Furthermore, the dataset is released on condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from its authorized or unauthorized use. The SWOT_ADCP_Dataset is intended to be used at the discretion of the end user in various analytical procedures desired by the end user, with the user fully aware of the limitations of the data. Data are presented in their raw form as retrieved from the SiteVisit field measurement database and are provided as-is. The user should take into account that some data may not be rounded resulting in excess precision being expressed, and typos and other erroneous data may be present.
