AdcpXP Software (Release II)
March 1, 2008
AdcpXP is a
customized software developed at The University of Iowa's IIHR—Hydroscience
& Engineering (IIHR). The software provides a wide range of flow
characteristics derived from velocities measured by Acoustic Doppler Current
Profilers (ADCP). In this initial stage, the software uses standard output
files produced by Teledyne RD Instruments’ Rio Grande and StreamPro ADCPs
(www.rdinstruments.com/rio.html). AdcpXP is a stand-alone application fitted with graphical user interfaces
that was developed with C++ and operates on Microsoft’s Windows platforms.
The software complements TD RDI’s WinRiver software
that is primarily related to the estimation of stream discharges. AdcpXP
brings in new visualization and post-processing capabilities to obtain
additional flow characteristics enhancing the value of the measurements
collected at fixed points or from moving vessels. The analysis can be
conducted in a point, vertical, transect or at the reach scale. A summary
of the AdcpXP capabilities is listed below.

Estimation of the main flow
direction and conversion of velocities in stream coordinates
-
Estimation of stream bulk
flow characteristics (Froude number, aspect ratio, hydraulic
radius, bulk stream velocity)

Visualization of secondary
flow (cross section)
-
Visualization of
cross-section velocity distribution and depth-averaged
velocity profiles (streamwise & spanwise directions)
-
Estimation of the unmeasured
edge bathymetry
-
Discharge estimation (using
both TD RDI and customized algorithms)

Spatial averaging of the
vertical and horizontal velocity distribution with variable
averaging step

All of the Above Collected with
WinRiver II |
The original AdcpXP was developed for ADCP data collected with
WinRiver I. Release II of the AdcpXP includes an additional
piece of code (HydroML2Summary) that converts data collected
with WinRiver II to a format that can be processed by the
original AdcpXP post-processing software. |
