Introduction
In numerical modelling, it is often important to check your model results with real-life observations. The 'Tide Stations' toolbox allows the user to both view and download water level time series. These time-series may be filtered for certain astronomical constituents. I is also possible to directly define observation points for Delft3D-FlOW. Dashboard makes use of IHO and XTide stations.
Usage - View and download water levels
A tidal station can be selected with the mouse from the Map View or chosen from the list of available “Tide stations”. There are three options available for each tidal station:
- “View Tide Signal” can be used to view the tide signal between “Start Time” and “Stop Time”.
- “Export tide signal” can be used to export the time series at the selected location in *.mat or *.tek format.
- "Export components" can be used to export the components of the tidal signal in *.mat or *.tek format.
Usage - Make observation points
An interesting possibility for the Delft3D-flow model is the option 'Make Observation Points'. On clicking, the user creates observation points within Delft3D-FLOW at all the locations of the tidal stations. When this option is combined with 'Export Tide Signal' a quick comparison of the accuracy of the simulation is possible. See also Tutorial 1: set-up a tidal model.
Figure: The Tide Stations toolbox makes it possible to both create observations points and view/export tidal signals as can be seen in this example where we export the tidal signal of a station at the coast of India
