RHABSIM Data Entry and File Conversion Screen Shots


Data entry in RHABSIM consists of stream cross-section bed profiles, velocity measurements, attribute measurements (substrate, shading, etc.), water surface levels, flows and other hydrologic parameters.

The FIELDAT and CONVERT modules incorporate a number of features for data entry, data file importing, and file conversions.

The first screen below is the FIELDAT main screen. RHABSIM data files can be designed to include up to 100 cross-sections of 300 data points each.

RHABSIM allows users to enter Bottom Profile and velocity data using direct values or by using Height-of-Instrument, rod readings and depth values for the bottom profile, and with Velocity Meters, revolutions, time, and angles to meter. The next screen below is the Direct Entry data worksheet where X (station) and Y (elevation) coordinates, up to five calibration sets of Velocity data and one or two Attribute values can be entered. If the user has entered the Water Surface Elevations for the calibration sets, RHABSIM will automatically flag points that are under water but have no velocity readings, and also points out of water that do have velocity readings.

The next screen is the data worksheet when the user creates a Bottom Profile using Height-of-Instrument, rod readings and depth values. When more than one data type exists (rod and depth or multiple depths from different surveys), the user has the option of selecting the single data column to use, or to average the available data.

The next screen is the Velocity Data worksheet when the user collects data using Velocity Meters, revolutions, time, and angles to meter. Users can load and save multiple Meter formula profile files and each Meter files can contain five algorithms. Data can be collected at one, two or three depths and then averaged. The user can choose to include angles or not and get a report of the difference in calculated vels.

The next screen below is a bottom profile and velocity graph where the user has chosen to show the calculated hydraulic information for a single calibration set. The user may also view all calibration sets together. A variety of options are available to allow the user full control over the graph presentation.

Once the user has built a number of cross-sections, RHABSIM can display a 3-dimensional graph of the reach. The user can select which cross-sections and calibration sets to show, rotate the reach in all three dimensions, and squeeze/stretch the length and width for best viewability.

Similar to the 3-D reach graph, the Velocity Histogram shows the bottom profiles and velocities for one or more cross-sections in a reach. The reach can be tilted up and down and problem cells (under water but no velocity, or out-of water with a velocity) are shown in contrasting colors.

As feature-rich as the RHABSIM DOS modules are, a dedicated presentation graph and report Windows program is included with RHABSIM.

The next screen below is the main screen for RHABSIM for Windows. Note that all modules (FIELDAT, HYDSIM, CRITERIA and HABSIM) are included for easy graph and report preparation once data are entered and models run.

The graph below is a screen shot of bottom profile and velocities from the RHABSIM for Windows module. The user has full control over scaling, fonts and data presentation. The graphs can even be printed in color!

RHABSIM has great ability to import and export data. The CONVERT module can easily import and export ASCII data, Acoustic Doppler data files, and old PHABSIM data files in the IFG4, MansQ and WSP formats. Users can set "IOC" strings and other data before exporting to PHABSIM.

RHABSIM has allows much greater control over methods and algorithms than PHABSIM. For example, RHABSIM allows different WSL and velocity methods at each cross-section (no more dividing reach files into pools and riffles!) When exporting from RHABSIM to PHABSIM, the program will report these discrepancies to allow greater understanding of differences the user might encounter in calculations.

The screen below is the CONVERT main screen...

A powerful feature of RHABSIM is it's ability to import Acoustic Doppler data files that have been exported from the ADCP program "TRANSECT", Version 2.65. ADCP files are created in the ASCII-OUT routine under the TRANSECT PLAYBACK menu (usually as "filename.000"). Each ADCP ASCII Doppler file represents one cross-section.

RHABSIM's CONVERT module makes it easy to import these files. Bearings of the cross-section and velocities can be automatically calculated and the user can preview the data in a graph before importing.

The following graph shows ADCP data (boat track), the calculated RHABSIM cross-section line and the average velocity bearing.
