Recent research has revealed that natural soil pipes provide important pathways for sub-surface movement of water and solutes, as well as contributing to landslide initiation. A benchscale experiment (in a sloping box 1 m in length) was conducted with a uniform sand to evaluate the effect of pipeflow on the overall hydrologic regime. A single drainage pipe (13 mm inside diameter (ID)) composed of five 20 cm segments, each with a different roughness coefficient (Manning's n), was placed 5 cm above the base of the 12.8° sloping box. Roughness elements were arranged in four different spatial combinations during hydraulic experiments. Piezometric levels were highest and pipeflow was lowest when the high-roughness (n = 0.325) portion of the pipe...
