This is very simple and the most straightforward flow modeling using HEC-RAS 5.0 which is capable of hydraulic modeling in 2-dimensional space.
The input files are not that much accurate and you may double check it again from the technical aspect. There are different parameters that should be defined and given as input to HEC-RAS 5.0.
The screen recording was done by the Webinaria program which is a free and open source program.
