Local Scour at the Elliptical Guide Banks

Scour development in time at the elliptical guide banks during the floods was studied. The dimensions of the upper part of the elliptical guide banks, namely the turn and length, were calculated by the Latishenko method.

Scour Development at Elliptical Guide Banks during Multiple Floods

The scour development at bridge abutments and elliptical guide banks during multiple floods is studied. At the upstream head of the elliptical guide bank, a streamline concentration, a local increase in velocity, vortex structures, and the development of

Local Scour at Straight Guide Banks in Plain Rivers

The local scour at abutments, elliptical and straight guide banks in plain rivers was studied. The flow pattern and the scour hole parameters at abutments, elliptical and straight guide banks are different.

Local Scour at Elliptical Guide Banks in Plain Rivers

The scour development in floods at abutments (Gjunsburgs & Neilands 2001, 2004, 2005, Gjunsburgs et al. 2004, 2005, 2006) and at elliptical guide banks is studied. The scour hole extents at abutments and guide banks are different. At the upstream head of

Scour Downstream River and Optimum Geometry of Flip Bucket in Tunnel with High Head and Large Discharge

工程科学与技术, 2007
:Experiments are carried out for the evolution of the hydraulic characteristics of the flow in the flip bucket and the scour downstream river. Measures are progressed for analyzing the feature of hydraulic characteristics and scour.
