Abstract

«RÉSUMÉ: Les débordements d’égouts unitaires peuvent causer des problèmes majeurs de pollution des cours d’eaux récepteurs. De plus, l'augmentation des surfaces imperméables, une conséquence de l’expansion des villes urbaines au cours du dernier siècle, a engendré une augmentation des volumes et débits de ruissellement des eaux pluviales. Ceci entraîne une réduction de la recharge des eaux souterraines, une augmentation de la masse de polluants rejetés et une érosion des berges des cours d’eaux récepteurs. Les pratiques de gestion optimales (PGO) favorisent les chances qu’un site retrouve ses caractéristiques hydrologiques initiales, avant développement, en gérant le ruissellement à la source. Ces nouvelles mesures de gestion des eaux pluviales, sous forme d’ouvrages à faible impact écologique, bénéficient de systèmes naturels pour augmenter l’infiltration et l’évapotranspiration.» et «----------ABSTRACT:Low Impact Development (LID) increases the chances for a site to have “predevelopment hydrology” by managing runoff at the source. New stormwater control measures (SCMs) in the form of structural micro-solutions (LID-Best Management Practices or LID-BMPs) have been implemented around the world as control strategies benefitting from natural systems to increase infiltration and evapotranspiration of stormwater. Hydrologic models permit the design of these projects and can be used to understand the benefits of implementing LID facilities into the landscape and predict their capabilities in handling a variety of rainfall events. Two types of LID structures were monitored in 2019 as part of a pilot project in Montreal; one with an underdrain pipe and runoff storage potential (bioretention basin) and the other without (vegetated swale). Their hydraulic performance was quantified using metrics such as bioretention abstraction volume, volume retention, peak flow reduction and peak delay.»
