The model SIMCAR solves the gradually varied unsteady flow in a branched canal network with upstream control, with particular attention given to the simulation of the AMIL radial gates. It is based on the Saint-Venant system of equations, which are solved by a finite-difference technique with a four-point implicit scheme weighted in time and space. Model calibration and validation are made for the canal network of the Sorraia Irrigation Project, Portugal.
