Deliverables:

It is recognised that the scope of the issues related to the effects of climate change on performance of urban drainage is wide. Because of this, AUDACIOUS will concentrate only on certain key aspects of the problem in detail. The following were envisaged to be the primary outputs for the original proposal, based on a range of potential climate change scenarios as specified by the Building Knowledge for Climate Change (BKCC) integrating framework (IF):

  1. A scoping study report, reviewing the issues, effects and interactions between local drainage and the wider urban system, and also the contextual interface with river-caused floods, identifying where new research initiatives will be required. This scoping study will be revisited at the end of the project.

  2. Downscaled rainfall timeseries, to point values at 1-5 minute timesteps, appropriate for use in small building and local catchment drainage analysis.

  3. An adaptable modified hydrology model, providing a key tool for urban drainage operators to be able to evaluate the likely changes in runoff, subsurface flows and interactions within drainage systems.

  4. A methodology for building drainage managers to evaluate and adapt a wide range of existing property drainage systems to account for climate change scenarios, considering also the need to attenuate increased flows locally.

  5. Guidance on the procedures to evaluate and manage the performance of local drainage systems and SUDS in the light of possible climate change scenarios. This will include sub-surface water interactions and additional storage, more proactive operation and alterations to ambient maintenance regimes. Implications for 'sewers for adoption' and vesting.

  6. Guidance on the alternatives to conventional urban drainage systems and changes in operational approaches to existing system and input system performance, and their resilience to climate change scenarios.

  7. Guidance to inform building regulation and standard setting.

  8. Guidance on the interfacial/boundary effects between building drainage, local and main drainage networks. Implications for the position of local urban drainage systems within CFMPs.

  9. Guidance for the management of local highway (non-trunk road) drainage.

  10. New model approaches to facilitate the more-effective analysis and routing of drain and sewer flood waves across urbanscapes in order to predict problems and devise responses. Including interactions between paved and greenspaces.

  11. Adaptable management solutions to coping with the problems, including local flood protection barriers and other devices aimed at preventing floodwater or drainage backflow from entering properties and other means of dealing with surface floods. This may also include operational measures such as Real Time Control to maximise capacity. (e.g. Bramley & Bowker, 2002; DTLR et al, 2002; CIRIA, 2002; Posford Duvivier; CIRIA 2002a).

  12. Guidance on the evaluation of each of the potential increased risks as a result of flooding, including health (primarily physical, but also including other aspects such as mental health).

  13. Guidance on the evaluation of risk and uncertainty for predicting the impacts and implementing alleviation responses based on the UKCIP, EA and other procedures.

  14. Procedures to determine the attitudes to risk and approaches to develop acceptable solutions (investment priorities), and to raise awareness amongst the various actors affected by potential changes to urban drainage system performance. Also aid with the facilitation of the implementation of the required responses from the various actors.

  15. Whole-life cost evaluations that include guidance on the apportionment and possible shift of economic burdens between the various actors concerned with urban drainage systems. Hence information on which regulators can base any revisions to performance standards and service levels.

  16. Case study applications demonstrating the drainage evaluation tools and mitigating management approaches above.

  17. Widespread dissemination of the tools and outputs in partnership with CIRIA,UKWIR, EA, ABI and others.
