Urban drainage patterns are altered by increasing urbanization and rapid conveyance and discharge of runoff, leading to increased flood risk, diminish of aquifer recharge and degradation of receiving waterways. These effects are expected to escalate with climate change. In response, alternative and more sustainable drainage practices with a holistic approach have been developed, although their wide-scale implementation has been limited largely due to socio-institutional barriers. This paper presents an innovative regenerative urban stormwater methodology for transition management at city level, containing two main enablers to overcome the barriers that drag out progress. First, a structured set of activities, the 'wheel', to guide and document the process, which is steered by a group of regional actors. Then, a visual and effective set of indicators that monitors and assesses the progress achieved and identifies the strategies to move forward. Its successful application to Benaguasil, a Mediterranean city, reveals that by integrating the views and strategies from actors at different but interconnected scales and following a structured but flexible methodology, it is possible to make progress in only few years and have a promising future ahead. © 2015 Elsevier Ltd.

This paper presents the performance of a number of sustainable drainage systems (SuDS) in the city of Xàtiva in the Valencia Region of Spain relatively soon after their construction. The systems studied comprise two roadside swales, one detention basin receiving runoff from one of the swales and one green roof to a school. The SuDS were installed under an EU LIFE+ project intended to demonstrate their practicability, application, and behavior under Mediterranean rainfall conditions. Most of the systems installed were in new developments but the green roof was retrofitted to a school within Xàtiva, which is a dense urban area. Full flow monitoring was undertaken and spot samples were taken to give a preliminary assessment of water quality performance. The early results presented in the paper demonstrate the effectiveness of the systems under typical Mediterranean conditions, which comprise intense rainfall from September to December and little or no precipitation at other times of the year. It is concluded that SuDS can be effectively introduced in the Mediterranean region of Spain. Full flow monitoring was undertaken in Xàtiva, Spain, and spot samples were taken from two roadside swales, one detention basin and one green roof to give a preliminary assessment of water quality performance. The preliminary results demonstrate the effectiveness of the systems under typical Mediterranean conditions. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

This paper reports on a study of the implementation of sustainable urban drainage systems (SUDS) in two Spanish towns (Xàtiva and Benaguasil) as part of the EU LIFE+ Project AQUAVAL, which has been conceived to introduce examples of sustainable drainage to the Valencia Region of Spain. Six sites in a range of common urban spaces and land uses are selected and appropriate SUDS techniques proposed by means of a decision-support process. This primarily consisted of the systematic application of key selection criteria through matrices and scores, followed by a brief sustainability analysis. Stakeholders' preferences and opinions as well as educational and social opportunities are highly considered throughout the process. General monitoring requirements and major limitations in using the methodology are outlined, stressing the need for improvement of four main aspects: local data regarding SUDS performance, detail of the sustainability analysis, support through comprehensive modelling tools, and level of stakeholder engagement. The importance of creating showcases for SUDS in Mediterranean Regions, thus adapting key selection criteria as to foster sustainable drainage understanding and expertise is highlighted. © IWA Publishing 2012.

This paper reviews the devices suitable for building scale application and then outlines three case studies, two from Coventry, UK and one from Valencia, Spain. The first assesses the potential to retrofit an extensive green roof to the Frederick Lanchester Library, Coventry University. Costings are given, the structural strength of the building is investigated and various benefits of its installation, including potential to sequester and store carbon, are assessed. The second reports part of the AQUAVAL Project, Spain, whereby an extensive green roof was retrofitted to half of a school roof and porous concrete retrofitted to a pavement. Preliminary monitoring results show expected benefits, including attenuation of the storm peak and increased time to peak. The third case study using WinDes® software compared a conventionally drained new-build housing estate with a Sustainable Drainage Systems train of porous paving, bioretention and swales. Stormwater volume was reduced by ̃20% and peak flow by >250 L s-1. Addition of extensive green roofs to all buildings increased these differences and delayed return to baseflow conditions reflecting water stored in the management train components. © IWA Publishing 2013.

Flooding events may become devastative phenomena in many urban areas due to the increase of the density population in prone zones. Therefore, new tools have been developed to assess the existent risk. As an example, this paper describes the SUFRI Methodology for pluvial and river flooding risk assessment in urban areas to inform decision-making, developed within the SUFRI project (ERA-Net CRUE initiative, 2009-2011). This methodology proposes the use of F-N graphs as a comprehensive tool which can be applied for evaluating all type of flood risk sources. Flood risk is quantified by studying different flood scenarios and incorporating available information on their probability of occurrence and potential consequences into risk models. Software based on the use of influence diagrams is suggested to compute risk. Two case studies are presented to show the estimates on flood risk and the effect of non-structural measures in risk reduction. © 2012 Taylor & Francis Group.
