Project overview
Aim:
Assess the role of city scale GI in the fulfillment of key environmental (water quality and carbon footprint) and socio-economic objectives (whole life cost).
Objectives:
Identify and select adequate methods and tools for the planning and assessment of GI.
Select suitable case study areas representative of drainage conditions and systemic problems within the NWL region.
Propose a variety of generic GI interventions that serve typical urban development forms of the case study areas.
Optimise
the selection and placement of
SuDS
for a number of performance objectives: receiving water quality, energy use/carbon footprint of the system, and whole life costs.
Elaborate recommendations for the planning and implementation of
SuDS
at the city scale (e.g. potential barriers).Slide6

Project overview
Review stage:
GI planning, performance criteria & assessment, IUWWS and GI models. Tools and identify data requirements. Uncertainties of model results. LITERATURE REVIEW.‘Benchmark’ stage: Construct SIMBA 6 model for ‘benchmark’ case study. Prepare and test all the necessary tools for the assessment and simulation of GI. TEST APPROACH TO PROBLEM AND SET STRUCTURE.
Case study stage: Selection of adequate case study and collection of data, ready to construct a SIMBA 6 integrated case study and set up all the necessary tools. Collection of results. PROJECT’S CORE.Reflective work stage:
Assess and compare results and identify potential barriers to the implementation of GI schemes. Reflect on the relative merits and demerits of different interventions. ANALYTICAL STAGE.Slide8
Answers?
What level of investment is required to simultaneously improve the condition of urban watercourses and reduce the carbon footprint of the system? How do GI solutions compare with conventional solutions?
Are there any significant trade-offs between objectives?What type of GI solutions are more effective in delivering specific objectives in the large scale? And for specific urban development forms?What barriers could potentially constrain the implementation of specific GI solutions?
Are there any additional benefits to be realised in the control-side of the system?
