Long term efficiency analysis of infiltration trenches subjected to clogging

Research output: Contribution to conferenceOther

Abstract

Abstract: In recent years, limitations linked to traditional urban drainage schemes have beenpointed out and new approaches were developed introducing more natural methods forretaining and/or disposing of stormwater. Such practices include infiltration and storagetanks in order to reduce the peak flow and retain part of the polluting components. The impactof such practices on stormwater quantity and quality is not easily assessable because of thecomplexity of physical and chemical processes involved. In such cases, integrated urbandrainage models may play a relevant role providing tools for long term analysis. In this study,the effect of the clogging phenomenon has been assessed by means of a simplifiedconceptual modelling approach developed in previous studies has been employed anddifferent soils as well as different design criteria have been considered. On the basis of along-term simulation of 6 years rain data, the performance as well as the effectiveness of aninfiltration trench measure are assessed. The study confirmed the important role played bythe clogging phenomenon on such infiltration structures.
