This report provides general information on non-visual methods of testing.
The Environment Agency has developed a structured procedure for obtaining and recording data on the National Sea and River Defences in England and Wales. The current system outlined in the Flood Defence Management Manual (FDMM) and supported by the Flood Defence Management System (FDMS) utilises a tool for visually assessing the condition of assets called the National Sea and River Defence Condition Assessment Manual. This provides a central inventory of the location and condition of component parts of flood defence systems. The current Environment Agency asset inspection system is principally visual. As part of its efforts to improve the condition assessment of its flood defence assets, the Environment Agency wishes to investigate the use of non-destructive testing within its asset condition assessment process.
