“…This research not only enabled the solution of the governing equations descriptive of the prevailing flow conditions in multi-outlet systems but also provided the foundation for subsequent development of new simulation approaches that extended applicability of the model to a broader range of piped networks that now encompasses all components of the property-based drainage system; a move that prompted a renaming of the model given the extended scope of application. 9,10 Outlet characteristics and representation of blockage…”

This paper presents the findings of an 18-month study of detritus accumulation at two siphonic rainwater drainage systems installed in a building in Edinburgh. Findings are based on an analysis of data recorded from the site, and are positioned within the context of enhancing representation of the outlet loss coefficient used within both steady-state design calculations and finite-difference-based unsteady flow modelling techniques. The scope of findings reported herein is extensive but, in the main, shows how detritus accumulation not only builds relatively rapidly but also that 'wash-through' or 'displacement' occurs. Further, data suggest that detritus accumulation in the gutter, that is either wind-blown or is introduced from roof runoff, can, and does, build around the outlet with only relatively low intensity rainfall but that high-intensity rainfall events do seem to result in a direct and significant increase in blockage. An indication of the impact upon performance, assessed using simulation software, is also presented. Practical application: This paper reports patterns of detritus accumulation at on-site siphonic rainwater outlets. Changes in detritus 'categories' are mapped to corresponding weather data and conclusions drawn on influencing factors. The paper therefore yields key information for building owners/operators on the extent of detritus accumulation at siphonic system outlets. Outcomes also inform designers of the potential shift in loss coefficient and flow performance post-installation.

“…Specific planning actions for adaptation should be targeted to the identified vulnerabilities of a particular area, but might include items such as resizing pipes to address a future of more intense storms (Kirshen et al, 2004(Kirshen et al, , 2008) using more green infrastructure to provide for cooling and on-site stormwater management (Ashley et al, 2007;Gill et al, 2007), anticipating the effects of climate on transportation systems (Suarez et al, 2005), mapping anticipated sea level rise (Frumhoff et al, 2007;Rosenzweig et al, 2007), encouraging building only outside of the zone of likely flooding and designing buildings for maximum natural cooling (Hacker & Holmes, 2007;Smith & Levermore, 2008), anticipating urban heat waves (Stone, 2005(Stone, , 2012, and seeking to understand how a changed climate also changes the meaning of a place (Hunter, 2008). Economics of policy choice also plays an important role, as persuasively demonstrated by the widely reviewed report by Stern (2007), and legal questions are beginning to be framed (Nolon, 2009;Wold et al, 2009).…”
