hydrographs are provided by Electricité de France (EDF). The topogra-
phy of the Toce River physical model is shown in Figure8.25. It covered
an area of 46 m × 10 m. The river was initially dry with a rectangular
tank located upstream. Two different tests were conducted in the physi-
cal model, one without the overtopping and the other with overtopping
of the reservoir in the downstream river reach. The corresponding inow
hydrographs (HY1 and HY2, respectively) are shown in Figure8.26 for
these two tests and used as inow boundary conditions. For both tests,
