The hydraulic study conducted was commissioned for the construction of the bypass for the “Salaria road, near the town of Monterotondo. It is one of the implementations of the broader planning of the Tevere Media Valle, aimed at the hydraulic safety of these territories, while respecting the legitimate urban development needs of the small towns within them and the hydraulic preservation of the metropolitan area of Rome. The second part of the “Monterotondo Scalo Variant” project is divided in 2 phases, the first one is the construction of a bypass road around Monterotondo on an embankment prepared and built to become a levee, when all the complementary hydraulic works of active and passive defense works by Lazio Region will have been done. For this reason, all the arrangements were made from the design necessary so that the road embankment would have the mechanical and hydraulic characteristics to fulfill the function of embankment, verifying that until the works complementary works are not realized it will be transparent with respect to the flood of the Tevere, so as not to aggravate conditions downstream and thus in the metropolitan area of Rome. The analyses carried out involved two-dimensional modeling of the Tevere river for a total stretch of about 15km, for the pre- and post- intervention scenarios.
