Sustainable urban drainage systems (SUDS) call for collaborative and interdisciplinary practices. The problem with this is the social and technical complexities involved, and the absence of a shared understanding of the challenge and the scope of integrated solutions. It is necessary to clarify the contributions and interactions between disciplines in order to achieve integrated planning and design of SUDS. This paper reviews the literature across disciplinary fields and outlines key messages and uncertainties within each discipline. The outcome is a framework comprising time, space and human values, as well as biophysical processes (e.g. engineering), spatial strategies (e.g. urban design) and adaptive strategies (e.g. management). It identifies the planning of SUDS as a collective leaming process with continuous iterations between disciplines, while also reflecting the past, present and future of a spécifie site.
Abstract:The hydraulic performance of permeable pavement (PP) systems has been well demonstrated when based on full or partial on-site infiltration, while there is only limited research on lined PP systems built to provide detention and volume reduction by evaporation only. In this study, we tested the performance of commercially available PP components when constructed as lined PP systems with un-throttled discharge to explore basic hydraulic function in a real-life-setting. Four types of PP surface products and three types of sub-base aggregates were tested in six unique combinations, built as side-by-side parking lots into an existing parking area, each stall having a size of 25 m 2 and 0.5 m of depth with individual lining. Based on 12 months of monitoring precipitation and discharge from each stall, total volume reduction ranged from 3% to 37%. Analysis of up to 22 single events, representing return periods of up to two years, revealed marked detention capacities, expressed as median volume reduction of 40%, spanning 27-69% and median lag time of 1:38 h, spanning 0:39-3:16 h, across all stalls. The considerable range in hydraulic properties can be ascribed to both surface and sub-base properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
