IFI’s National Barriers Programme (NBP) developed a field survey to capture information on barrier location, type and associated images and structure dimensions. This form was used as a Level I assessment measure to find and locate barriers. The NBP has delivered a geo-referenced database fully integrated with EPA-WFD coding and instream structures can then be assessed by EPA sub-Catchment or waterbody codes. This is the framework with structures assessed during on-site visits are now populating.
