View source for TUFLOW Rainfall Control File Examples

=Introduction=
This page contains some simple rainfall control file examples.<br>
The Rainfall Control file is referenced in the tcf by the command: <br>
<font color="blue"><tt>Rainfall Control File </tt></font> <font color="red"><tt>==</tt></font> <tt><filename> </tt> <br>
The model setup is a very simple square model, with a series of rainfall points within or close to the model area, as shown in the image below.  The dashed outline is the TUFLOW model area and the labelled points are the 2d_rf point locations which are labelled by the "Name" attribute.<br>
The purpose of  the model is only to demonstrate the point rainfall to gridded rainfall functionality.  The rainfall and locations are 100% made up!

The provided rainfall control files, use the same temporal pattern but different depths of rainfall.  For the points listed above the rainfall depths are outlined in the tabel below:<br>
'''Total Rainfall Depths'''

For each of the interpolation method the total rainfall depth is shown.  The colouring is the same for all of these grids, with the legend shown below.<br>
