Abstract:This paper will compare and contrast a number of international approaches to the hydraulic control of surface water runoff from new development and redevelopment, know as sustainable drainage systems (SuDS) or low impact development (LID). The paper will provide a commentary on the progress and current status of national standards for SuDS in the UK to control the frequency, flow rate and volume of runoff from both frequent and extreme rainfall events, and the best practice design criteria presented in the revised UK CIRIA SuDS Manual, due to be published in October 2015. The paper will then compare these design criteria and standards with those developed and applied in China, USA, and Germany and will also look at the drivers behind their development. The benefits of these different approaches will be assessed in the context of flood risk mitigation, climate resilience and wider environmental protection objectives, including water quality, morphology and ecology. The paper will also review the design approaches promoted by the new Manual and internationally for delivering additional benefits for urban spaces (such as recreation, visual character, education and economic growth) through multi-functional urban design.
