Effect of Upward Seepage on Scour and Flow Downstream of an Apron due to Submerged Jets
(Preview)
Introduction
The topic of scour downstream of an apron due to a submerged jet issuing from a sluice opening has been well explored due to its practical applicability in the context of the stability of hydraulic structures (Chatterjee and Ghosh 1980; Hassan and Narayanan 1985; Chatterjee et al. 1...

Scour of River Bed
(Preview)
Scour of River Bed
Scouring of riverbed is caused by natural phenomena as well as by imposed structure like bridge piers. Scouring due to natural reasons is called general scour and takes place on large space-time scales. The principal reason for general scour in large river systems is geomorpho...

Effect of Superstructure Submergence
(Preview)
Effect of Superstructure Submergence
Scour at submerged bridge is shown in Figure 6.43. Submergence of the superstructure leads to an increase in scour at the bridge foundations compared to that at an unsubmerged bridge. Some guidance is available for estimation of scour depths at submerged b...

Characteristics of Turbulent Flow in Submerged Jumps on Rough Beds
(Preview)
Introduction
Free and submerged jumps are important phenomena in open channel flow because of their applications in energy dissipation downstream of hydraulic structures, such as spillway, barrage and weir. Because of their various engineering applications, jumps have been the focus of...
