Modelling flood events in the Arno River and the interaction with the infrastructures in the city of Florence using REEF3D

Abstract

The first part of this work provides the numerical model overview including the governing equations, the turbulence model and the discretization methods. The second part describes the geographical position of Florence, its hydraulic history and the data collected on the river reach in the urban part. In the third part, some experimental cases analysing the flow around the piers and over a weir are introduced in order to validate the software performance. In the last part, the case study is presented. The results obtained from the simulations are discussed and analysed to get a in-depth understanding of the flow phenomena in the Arno river.
