EPSRC Grant: EP/FP202511/1 Challenges of infrastructure management Paul Sayers, Leader SWP4 – Infrastructure Management Adrian Saul, Leader SWP3 Urban risk - University of Sheffield

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 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)

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.
