TUFLOW Rainfall Control File Examples

Introduction

This page contains some simple rainfall control file examples.
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.
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:
Total Rainfall Depths

Boundary Name	Total Rainfall Depth (mm)
RF1	30
RF2	60
RF3	90
RF4	120
RF5	150
RF6	180
RF7	210
