Surface Velocity Tools (SurfVelTools)

SurfVelTools is a Python application and user interface for computing parameters associated with the Probability Concept method (Fulton and others, in review) parameters using velocity profile data collected in the stationing where the maximum in-channel velocity occurs. SurfVelTools will also compute streamflow (discharge) for a given Probability Concept result given a known cross-sectional area, phi, and surface velocity—all variables measured in the field at a typical surface velocimetry gage. SurfVelTools enables rapid determination of these parameters and streamflow with uncertainties, including profile fit evaluation. Results can be archived and
exported for recordkeeping purposes.
