Flanagan, Sam A.; Furniss, Michael J.; Ledwith, Tyler S.; Thiessen, Stan ; Love, Michael A.; Moore, Kemset ; Ory, Jill . 1998. Methods for Inventory and Environmental Risk Assessment of Road Drainage Crossings. 9877 1809P. Water/Road Interaction Technology Series: Volume Issue .

Road-stream crossings and ditch-relief culverts are commonly sites of ongoing or potential erosion. Erosion from failures of these structures can be a source of significant impacts to aquatic and riparian reesources far removed from the initial failure site. The inventory and assessment of culvert installations are necessary for locating sites with potential impacts to aquatic and riparian environments for possible treatment. Locating those sites with the greatest potential for causing adverse impacts and reducing or eliminating those impacts is critical in prioritizing restricted funding available for road maintenance and repair.
