Acoustic Doppler current profilers (ADCPs) provide detailed, three-dimensional velocity data that includes valuable information about the flow structure, yet much of this data is never fully utilized due to a lack of post-processing software for ADCP data. While ADCPs are most commonly used by the USGS for discharge measurements, the data they collect can provide modelers with calibration and validation data for 2-D and 3-D hydrodynamic models. In addition, ADCPs can provide high-resolution velocity data required for many environmental studies. This short course will focus on the planning required for a velocity survey, the equipment and procedures required for execution of the survey, and application of the Velocity Mapping Toolbox (VMT) to process, analyze, and visualize ADCP data. VMT is a Matlab-based software for processing and visualizing ADCP data collected along transects in rivers or other bodies of water. VMT allows rapid processing, visualization, and analysis of a range of ADCP datasets and includes utilities to export ADCP data to files compatible with ArcGIS, Tecplot, and Google Earth. The software can be used to explore patterns of three-dimensional fluid motion through several methods for calculation of secondary flows (e.g. Rhoads and Kenworthy, 1998; Lane et al., 2000). The software also includes capabilities for visualizing the acoustic backscatter and bathymetric data from the ADCP. A user-friendly graphical user interface (GUI) enhances program functionality and provides ready access to two- and three- dimensional plotting functions, allowing rapid display and interrogation of velocity, backscatter, and bathymetry data. In addition to the Matlab source code, a compiled version of VMT is available for users without access to Matlab.
