Summary

The mission of the U.S. Geological Survey (USGS) involves providing reliable, impartial, and timely information that is needed to understand the Nation’s water resource. New techniques that aid in achieving this mission are important, especially those that allow USGS to do so more accurately or cost-effectively. To this end, a new method for selecting the optimum exposure time for velocity and discharge measurements has been explored. These data were assembled to assist in the development and evaluation of this new method. Four kinds of time-series data are available and used for this purpose. They are: (1) model-derived synthetic velocities, (2) point-velocity measurements in laboratory flumes, (3) point-velocity measurements in streams, [...]

Purpose

The purpose of these data is for developing and evaluating a method to dynamically estimate the exposure time, the time required to accurately sample the flow when making turbulent flow measurements. Laboratory ADV data were originally collected as part of the work to develop ADV performance curves and for a model study in a large indoor flume. Field ADV and ADCP discharge measurement data were collected by the U.S. Geological Survey as a part of routine data collection in its hydrometric networks.
