Flow of water in a soil profile: a gravity dam simulation

We present here a task carried out by our students in the Environmental Modeling subject. They implemented a routine in Matlab/Scilab/Octave high-level interpreted language in order to simulate the flow of water in a soil profile. Their hypothetical study case was a gravity dam. They performed two simulations 1) steady simulation, with the reservoir water level kept constant and 2) unsteady simulation, with the level changing from 10 meters to 50 meters and form 50 meters to 10 meters, whereas the downstream level was kept constant.
