Under construction

 

The XBeach menu in Delft Dashboard resembles the different modules in the XBeach source code. More information can be found in the XBeach manual. All the default parameters are used in the windows. When the default is not changed, the keyword will not end up in your XBeach configuration file (i.e. params.txt)

Description

Toolbox

To perform a number of operations according to the Toolbox selected from the Toolbox tab in the Top Menu.  For all the supported models this is the quick mode of the model maker and the possibility to combine several sources of bathymetry.

Model physics

The data Group Model physics offers the user to selected which XBeach modules (e.g. swave, flow morphology, eg.) one wants to run. On top of that physical constants like gravitional gravitational acceleration and rho and fluid density can be specified. The physical advanced options are not yet operational.

Model domain

 

The data Group Model domain contains the following sub-data groups: Grid parameters, Initial conditions and advanced options

  • Grid parameters: in thus sub data group all the parameters related to the hydrodynamic grid (nx, ny, etc.), but also of the wave grid (thetamin and thetamax) can be set. XBeach offers user to work with a XBeach or Delft3D grid, so it is possible to to simply select a Delft3D grid with the button xyfile.
  • Initial conditions: gives the user the possibility to define the initial water elvel
  • Advanced options: at the moment only the option to enable hotstart flow is implemented.

Model Domain options are not yet operational

Time inputThere are two settings which need to be set in order to do a an XBeach simulation. First of all the simulation time in seconds (tstop) needs to be set. Secondly, the time step used in the hydrodynamic simulation is determined based on a given maximum Courant number using the keyword CFL.
Wave input@The majority of the keywords related to waves (e.g. boundary conditions, breaking parameters) can be set here.
Flow input@The majority of the keywords related to flow (e.g. boundary conditions, bedfriction) can be set here.
Sediment input@The majority of the keywords related to sediment transport (e.g. waveform, facSk, facAs) can be set here.
Morphology input@The majority of the keywords related to morphology (e.g. rho, morfac and wetslope) can be set here.
Output options@The majority of the keywords related to output (e.g. tintm, tintp) can be set here.
Advanced input@More parameters can be defined under 'advanced input'.
