Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 Due to the lack of any specific study about the sidewalls and other blocks’ changes in the case of hydraulic and scour downstream, the present study was conducted to investigate this issue. For this purpose, drainage projects and spillway chutes, as well as many baffle block chutes, were designed and constructed with the parallel sidewalls and ...

Experimental Investigation on Augmenting the Discharge over Ogee Spillways with Nanocement [PDF]
Civil Engineering and Architecture, 2020 Due to urbanization, the infiltration has decreased drastically resulting in more runoff. Due to this, dams are receiving more runoff than the design runoff. To avoid over topping of dams due to this excess runoff, the capacity of the spillways has to be augmented. The objective of this research is to determine the effect of nano material on increasing

Numerical Simulation of the Hydraulic Performances and Flow Pattern of Swallow‐Tailed Flip Bucket
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 In this study, the evolution process of the swallow‐tailed flip bucket water nappe entering into the plunge pool is simulated by using the standard k‐ε turbulence model and the volume‐of‐fluid method. The effects of the upstream opening width ratio and downstream bucket angle on the flow pattern, the unit discharge distribution, and the impact pressure
