Local scour downstream of a weir is a common problem that can result in serious damages to the weir itself. This study presents results from large eddy simulations (LESs) for surface jets over a submerged weir. Turbulent surface jets were computed over the flat and deformed beds due to scour for the same approach flow. The mean flow and turbulent statistics are presented for both flat and deformed bed conditions. Turbulent flows with the scour hole show that the reattachment region startingdoi:10.3850/38wc092019-0576 fatcat:q2ypw6qenvcrxbemnyam7bmpiq
