Chapter 30 - Sustainable urban drainage system model

Abstract

This chapter presents a case study that seeks to establish new sustainable urban drainage systems (SUDS) decision support tools for planners, and to compare the outcomes for Edinburgh and Glasgow with each other. 79 and 103 sites within Glasgow and Edinburgh, respectively, were identified to assess, if SUDS can be integrated into future development, regeneration, and retrofitting plans. The optimization model for SUDS implementation in Glasgow and Edinburgh utilized the site classification data to suggest a suitable SUDS solution either as an individual SUDS technique or as a combination of two techniques in the form of a SUDS treatment train. A practical SUDS Decision Support Model based on a matrix and weighting system, incorporating the Prevalence Rating Approach for SUDS Techniques (PRAST) was also developed. The findings indicate that ponds or lined ponds and permeable pavements are the most likely individual SUDS techniques, and ponds combined with standard swales or shallow swales are the most recommended combination of two SUDS techniques. A separate case-based reasoning (CBR) model compared to the linear SUDS Decision Support Model was also developed. The outputs of both models were similar indicating that the linear model works similar to the human mind.
