SMS:BOUSS-2D Probes

BOUSS-2D Probe Manager dialog

BOUSS-2D can output the histories of the computed water surface elevation, velocities, force, and pressure at every grid point and at every time step. However, due to the number of data points in the domain, this is usually done at intervals of 15-30 min.

In order to provide a more complete temporal representation of the results of the calculation, the model allows specifying probes. At a probe location (x,y,z), specify what data should be saved and at what temporal resolutions. The options include water surface, velocity, force, and pressure.

Example of the BOUSS-2D Pressure Probe Options dialog. The UV Probe Options dialog is similar.

The probe manager allows creating, editing, and deleting probes. This dialog is only accessible when a BOUSS-2D grid exists. The properties associated with probes as follows:

• *.ts1 solution data loaded – Indicates the highlight color for any fields that have solution data loaded.
• Create Probes at Selected Cells – This button will add probes to the probe list using any cells that were selected when the Probe Manager was opened.
• Unload All *.ts1 Solution Data – If any *.ts1 solution data has been loaded for any of the probe properties, the fields with that data will be highlighted. Clicking this button will unload the the solution data, allowing a new solution file to be generated when BOUSS-2D is run again.
• Asign position by: – These options will determine which coordinate fields to use in positioning the probes.
  • Cell Position (I,J) – Activates the i and j fields.
  • (X,Y) Coordinate – Activates the x and y fields.
• Color – Clicking on this button will bring up Color dialog. Altenatively, a simple color picker can be accessed by clicking on the arrow to the right.
• Name – A default name will be entered in this field, but by selecting the field any name can be typed in.
• x and y coordinates – These fields are only available when the (X,Y) Coordinate option is toggled on under the Assign position by: section. When active, specific coordinates may be entered which will move the probe on the grid.
• i and j coordinates – These fields are only available when the Cell Position (I,J) option is toggled on under the Assign position by: section. When active, specific coordinates may be entered which will move the probe on the grid.
• WSE – When checked, specifies using available water surface elevation data.
• Pressure – When checked, specifies using available wpressure data. The Options button will bring up the Pressure Probe Options dialog where elevation data can be entered.
• Velocity – When checked, specifies using available velocity data. The Options button will bring up the UV Probe Options dialog where elevation data can be entered.
• Force – When checked, specifies using available force data.

A probe can be deleted from the Probe Manager list by selecting the probe row number and hitting the Delete key.

Viewing Probe Solutions

After running the BOUSS-2D model, probe solution files are generated. These files can be imported into SMS to view the probe data. Right-clicking on a probe cell will have the following options for viewing probe data:

• Eta Time Series Plot – Creates an eta time series plot.
• Basic Statistical Analysis – Brings up a Eta Basic Statistical Analysis dialog.
• Zero-crossing Analysis – Brings up a Zero-crossing Analysis dialog.
• Spectral Analysis – Brings up a Spectral Analysis dialog showing a spectral plot.

Basic Statistical Analysis

Example of the BOUSS-2D Eta Basic Statistical Analysis dialog

The Basic Statistical Analysis dialog includes the following information for each probe:

• Mean (m)
• Minumum (m)
• Maximum (m)
• Standard Deviation (m)

Zero-crossing Analysis

The Zero-crossing Analysis dialog

The Zero-crossing Analysis dialog contains the following information for each probe:

• HAV (m) – Average wavelength for the full time series.
• H13 (m) – Average of the highest 3% of Water Surface Elevation.
• H110 (m) – Average of the highest 10% of Water Surface Elevation.
• HMAX (m) – Highest Water Surface Elevation.
• TAV (s) – Average time periods for the full time series.
• T13 (s) – Average of the highest 3% of time periods.
• T110 (s) – Average of the highest 10% of time periods.
