Streambed instabilities and nature of turbulence around bridge piers in a dredged channel

Abstract

Extraction of sand from streambed has catastrophic repercussions on aquatic animalia habitat surface water quality and environment Sand mining in an active alluvial channel can compromise the streambed stability of the hydraulic structures nearby The complex nature of flow approaching and interacting with the bridge piers after passing over a mining pit and the streambed response around the piers is not fully understood Gravity flow experiments were performed in a sand bed channel to invest...
