Abstract
Protection below overhanging culvert outlets is required to prevent scour and negate or minimize pipe undermining. Large culverts may need reinforced concrete protection, but for smaller culverts a more economical and satisfactory means of protection can be provided by using field stone.
A three-dimensional model study of scour below overhanging culvert outlets was made.
Testing in a plain sand bed was done first in order to outline the process by which scour occurs at an overhanging culvert outlet and the extent to which it occurs.
Preliminary tests on the placement of rip-rap to reduce scour were then done to test various placement configurations. These tests were qualitative and no design procedure came about from their results.
Testing in a plain rock bed was then done, and from this series of tests a design procedure for protection against scour at an overhanging culvert outlet was formulated.
