The effect of artificial roughness on bed topographic downstream of a culvert in response to variations in longitudinal slope. [PDF]
Sci RepThe flow being discharged from the culvert during flood events leads to significant alterations in the topographical features of the downstream bed. These modifications, manifested as scouring, have the potential to compromise the structural integrity of
