This Show and Tell session provides an introductory tour of the modernized USGS Water Data for the Nation interface and tools available at waterdata.usgs.gov.
The USGS Continuous Water-Quality community maintains a large network of real-time instruments. Throughout the country, the USGS is collecting over 6,000 continuous water-quality datasets at over 2,500 sites and measuring more than 8 water-quality parameters (temperature, specific conductance, pH, dissolved oxygen, turbidity, nitrate, chlorophyll, and Fluorescent Dissolved Organic Matter (fDOM)). Discover what CWQ resources are available for staff, who to contact with questions or suggestions, and what efforts are in progress.
To compute discharge using image velocimetry, the measured surface velocity must be related to the depth-averaged velocity; this is typically done using a simple coefficient known as the alpha coefficient. The alpha coefficient is the most significant input to the computation of discharge from imagery that is often not empirically determined, but the resulting discharge value is directly proportional to the value chosen. The USGS database contains more than half a million ADCP measurements - the profiles in these measurements can be used to inform selection of alpha. Results from a compilation of profiles at a variety of sites will be presented.
The USGS has collected water data for over 135 years. The USGS Fundamental Science Practices (FSP) have been governing water data collection and publication for the past 17 years. How familiar are you with FSP as it pertains to water data? This presentation will (1) provide a broad overview of FSP, (2) show how FSP relates to water data collection and subsequent data publication, and (3) share available OSQI resources useful for when FSP questions arise.
This presentation will accomplish these objectives by examining three focus areas; (1) discussing data collection and approval obligations in SM 502.2 Fundamental Science Practices: Planning and Conducting Data Collection and Research and SM 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release, (2) relating adherence of Water Mission Area Techniques and Methods to adherence of Fundamental Science Practices, (3) discussing mechanisms for reporting FSP questions to the Fundamental Science Practices Advisory Council (FSPAC), quality concerns to OSQI resources, and integrity concerns to the USGS Scientific Integrity Officer. Listeners will leave the presentation with a better understanding of how FSP relates to USGS Water data collection and publication and where to turn to when concerns arise.
This presentation will be given by Gary Burke, a staff scientist from the Office of Science Quality and Integrity (OSQI). Gary was a Field Office Chief for 7 years prior to joining OSQI and had collected NWIS water data for over 20 years.
Manual data review and processing is time-consuming for USGS technicians - the USGS Water Community needs tools to help automate time-series data workflows. HydroCorrect is an AQTS toolbox that monitors data, identifies anomalies, and performs corrective actions based on rate of change, threshold, and flatline rules. In this session, we will demonstrate how HydroCorrect capabilities and workflows can make things easier for you! Join us to learn about opportunities to be part of a pilot testing group to be among the first to implement HydroCorrect and help shape the next iteration of water data tools for the USGS.
Overview of the cause and effect of a moving bed and methods to identify and correct for a moving bed when measuring discharge with an ADCP from a moving boat. This talk will also include a review of the moving-bed test results and what they mean.
Learn more about the USGS Continuous Water-Quality Community at this facilitated networking session. Meet your colleagues, make contacts, and discuss parameters and processes. Ever wish you had more time to ask peers about equipment or a challenge? Great ideas often come by having conversations with people about a shared problem or interest. During this session, employees will get the opportunity to share perspectives with a subset of peers working on the same topics.
