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!

Challenges of infrastructure management

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
Scale of the challenge
England and Wales• Annual expenditure on
maintenance / improvement approx. £450m
• £20 billion of sunk investmentWater companies• £100’s millions required!USA• US Corp of Engineers estimate $2.2
trillion to maintain levees at a “desirable” standard (Steve Stockton)
Some difficult questions….
Perform under load or on demand?
Improve or deteriorate
with/without action?
How will an asset…
Perform now and in the
future?Which assets
contribute most to risk?
How will the system...
Hot spots?Investment
need?How might
these change ?
What are the national…
A range of spatial and temporal scales of interest
How is the research in FRMRC helping?
Conclusions
Many more challenges …..
but FRMRC provides some innovative and useable advances.
