Modelling Site-scale Suds At The Street-scale
Supervisor: Dr Virginia Stovin
Urbanisation is usually associated with the replacement of permeable (green) surfaces with impermeable hard surfaces (roads, roofs, etc), which alter the catchment's response to rainfall. Stormwater runoff from urbanised areas tends to peak more rapidly and contain higher volumes of runoff than in undisturbed catchments. SuDS (Sustainable Drainage Systems), such as green roofs and rain gardens, provide an alternative to conventional piped drainage, but there are uncertainties surrounding the most appropriate methods for modelling SuDS in urban drainage hydraulic models. The focus of this project will be to transfer detailed understanding of site-scale performance, e.g. of a single green roof, to appropriate representation within commercial hydraulic models (InfoWorks, SWMM) applied at the city-scale. This will ideally include case study performance evaluations of retrofit SuDS options.
This project is NOT FUNDED, although Departmental/University scholarships are available for applicants who can demonstrate strong evidence of research potential.
