Steps to get started with FEWS XBeach model adapter
Define a location with "WGS 1984" coordinates
| Code Block |
|---|
|
<?xml version="1.0" encoding="UTF-8"?>
<locations version="1.1" xmlns="http://www.wldelft.nl/fews" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.wldelft.nl/fews
http://fews.wldelft.nl/schemas/version1.0/locations.xsd">
<geoDatum>WGS 1984</geoDatum>
<location id="Dummy" name="Dummy">
<x>4.601954</x>
<y>52.619469</y>
<z>0</z>
</location>
</locations>

Define a grid
| Code Block |
|---|
|
<?xml version="1.0" encoding="UTF-8"?>
<grids xmlns="http://www.wldelft.nl/fews" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.wldelft.nl/fews http://fews.wldelft.nl/schemas/version1.0/grids.xsd">
<irregular locationId="Dummy">
<description>Dummy</description>
<rows>71</rows>
<columns>155</columns>
<csvFile>
<file>dummy_grid.csv</file>
<geoDatum>Rijks Driehoekstelsel</geoDatum>
<x>%X%</x>
<y>%Y%</y>
</csvFile>
</irregular>
</grids>
|
Create .csv grid file
FEWS -F12 -S convert -netcdf file to cell centers csv file
Choose XBeach netcdf output file, a csv file with the same name will be created (place this in Config\MapLayerFiles\ directory) and example configuration will be added to the clipboard. Make sure the correct <geoDatum> is used, probably must be changed to "Rijks Driehoekstelsel".
Using Swan wave spectra in FEWS
Define parameters
"AFREQ" and "NDIR" are domain parameters needed for "EnDens"
