Dear Gazi,
Fortunately, this is certainly possible!
You can add rainfall as External Forcing.
In the MDU (model definition file unstructured) you refer to the external forcing file (extention .ext)
In this ext-file you define the types of external forcing which you add to the model
You multiple options for rainfall, for example spatially uniform, but time varying rainfall or spatially and temporally varying rainfall.
The first is done with a simple text file, for others you can use netCDF files.
In the case of spatially uniform rainfall, you refer to a file in which the course of the rainfall event is described.
This has the extension .tim (for time)
The format is time in minutes since simulation started and rainfall intensity in mm/hour for that timestep.
the software interpolates the amount of water which enters the model at each timesteps based on these values.
I've included an EXT-file with a list of all the options and a simple example rainfall event.
The example rainfall event is a quite severe shower for midlatitudes.
I hope this is usefull for you.
kind regards,
Marjanne
