Influence of short-term configurations of a mouth deviation on river hydraulics: the Pescara River case study

This paper aims to emphasize the importance of simulating river hydrodynamics for all the stages of river mouth deviations, since their potential influence on the flood hazard assessment. The case study of the Pescara River mouth deviation in the Abruzzo Region, Italy, has been considered. Only the realized steps of the project have been analyzed, for which the sea level at the mouth has turned out to not remarkably change for the considered layouts. Consequently, flooded areas and flow velocity do not significantly vary between the analyzed configurations. The adopted modeling chain has proved to be a suitable tool to support engineers, contractors, and controlling authorities in the different project phases.
