BOUSS2D Runup / Overtopping Model Control dialog

The BOUSS2D Runup / Overtopping Model Control dialog is accessed by right-clicking on the Runup/Overtopping simulation and selecting the Model Control command. The dialog allows setting the following parameters:

• Project Title – Enter the title of the project in this field. The title is used for the folder name where the output files will be stored.
• Input Datasets – These inputs specify spatially varied input parameters for the model. In addition to the bathymetry, BOUSS-2D can utilize spatially varied damping, porosity and currents. In this section, the user defines whether these inputs are used (“None” is selected if not), and if so, how they are defined.

• Damping – specified using boundary conditions on cell strings or selected from the scalar functions.
• Porosity – specified using boundary conditions on cell strings or selected from the scalar functions.
• Current – selected from the available vector functions.

• Time Control – The interface displays the recommended values for Duration and Time step in parentheses.

• Duration – enter the model run duration.
• Time Step – enter the number of time steps for the model run duration.

• Grid Information – This section displays the attributes of the active grid.

• Cell Size – specifies the size of cells the model run will use.

• Porosity Friction Factors

• Turbulent – value ranges from 0.0 to 3.6 with a default value of 2.4.
• Laminar – value ranges from 0 to 1500 with a default value of 800.
• Store Size – represents the characteristic stone size (d50) in meters of the breakwater armor layer and must be greater than zero.
• Added Mass Coeff. –

• Parameters

• Roughness Type – sets the Chezy coefficient type. Currently, only "Constant Chezy coefficent" is allowed. The Chezy coefficient ranges from 0.0 to 1000.0 (default = 50).
• Smagorinsky Number – must be between 0.0 and 2.0 (default=0.2).
• Nonlinear Option – can be set to either "Strong" or "Weak".

• Output Options

• Overide Default File Prefix – allows the user to specify a file name for these solution files. The default file prefix is the filename of the *.par file.

• File Prefix – becomes active once the Overide Default File Prefix is toggled on. A new prefix may be entered when active.

• Time Independent

• Output Significant Wave Height
• Output Mean Currents
• Output Mean Water Level
• Output Max Inundation Water Level
• Output Format – gives options to output in an "XMDF" file, a "BOUSS-2D Native" file, or "Both".

• Animation Output

• Output WSE – tells the model to output time varying datasets.
• Output Velocity – tells the model to output time varying datasets.
  • Number of Frames
  • Required Memory
• Override Defaults – Enables the Begin Output, End Output, and Step controls.
  • Begin Output – must be greater than 0.0 and less than the run duration.
  • End Output– must be greater than 0.0 and less than the run duration.
  • Step – determines how often the model will save time-varying output.
