Flood Risk Management in an Urban Area Applying LID Techniques

Abstract

We analyze the benefits of a practical application of Low Impact Development (LID) structures in an urbanized area in terms of reduced flooding volumes and peak flow. LID techniques are fairly economic and easy to implement solutions for the hydraulic restoration and improvement of the efficiency of existing urban drainage networks. The case study is the New Rome Fair, a recent urban development where flooding problems have been observed in the last few years. The study illustrates the potential of LID structures together with a dual system, and their impact on flooding occurrences, for two different Return Periods, highlighting the need for attentive and feasible applications of such structures in a heavily urbanized environment, harmoniously with the related architectural aspects.
