  3. Improving the management of flood infrastructure – Session Outline Presentations (6 x 5mins) • Challenges of infrastructure management (Paul Sayers) • Blockage – Its prediction and importance (Nick Wallerstein) • Gully performance - connecting above and below ground system(Slobodan Djordjevic) • Asset condition – linking remote and visual inspection(Martin Smith) • Breach growth – Rapid and more complex models (Myron van Damme) • Computer support for infrastructure planning decisions(Jim Hall) Plenary discussion (45mins) With the Panel taking questions from the floor – so remember your questions!

  4. Challenges of infrastructure management Paul Sayers, Leader SWP4 – Infrastructure Management Adrian Saul, Leader SWP3 Urban risk - University of Sheffield paul.sayers@sayersandpartners.co.uk a.j.saul@sheffield.ac.uk

  5. What are infrastructure assets? A wide range of assets: • Linear assets (above ground) • e.g. a raised defence (levee or dyke) through to major dams structures • Linear assets (below ground) • e.g. urban drainage networks • Interface assets • E.g. culverts, manholes etc • Point assets • e.g. a pump, gate or culvert trash screen • Watercourses and channels • E.g. the vegetation and sediment within a channel and floodplain • Coastlines • e.g. a groyne, beach or backshore

  6. Scale of the challenge England and Wales • Annual expenditure on maintenance / improvement approx. £450m • £20 billion of sunk investment Water companies • £100’s millions required! USA • US Corp of Engineers estimate $2.2 trillion to maintain levees at a “desirable” standard (Steve Stockton)

  7. Some difficult questions…. A range of spatial and temporal scales of interest What are the national… How will the system... How will an asset… • Hot spots? • Investment need? • How might these change ? • Perform now and in the future? • Which assets contribute most to risk? • Perform under load or on demand? • Improve or deteriorate with/without action?

  8. How is the research in FRMRC helping?

  9. Conclusions Many more challenges ….. but FRMRC provides some innovative and useable advances.

  10. The research reported in this presentation was conducted as part of the Flood Risk Management Research Consortium with support from the: Engineering and Physical Sciences Research Council Department of Environment, Food and Rural Affairs/Environment Agency Joint Research Programme United Kingdom Water Industry Research Office of Public Works Dublin Northern Ireland Rivers Agency Data were provided by the EA and the Ordnance Survey.
