Abstract: Conventional methods of energy dissipation by single‐fall hydraulic jump‐type stilling basin, roller bucket, or ski‐jump bucket may not be suitable for high dam spillways because of very high velocities at the end of the ...

Abstract: Existing methods for the design of an open channel transition between a rectangular flume and a trapezoidal channel for subcritical flow have been critically examined. Arising out of some fundamental considerations, a ...

Abstract: Settling basins are used on irrigation and hydropower channels to remove objectionable sediment of a specified size and quantity. They are formed by widening the approach channel and lowering its floor through an expansion ...

Abstract: Recent attempts have been made to reduce scour around solid circular piers. Such attempts use riprap, a circular collar around, a rectangular slot through, and a delta wing‐like fin ahead of piers. Providing another scour ...

Abstract: Sediment entry into irrigation and hydropower canals may be controlled by a sediment excluder at canal headworks and/or a sediment ejector on the canal downstream of headworks. These devices take advantage of the fact that ...

Abstract: An aqueduct is a canal conveyance structure utilized to cross a river when the bed level of the canal is clearly above the river high flood level. One such aqueduct structure is a reinforced concrete rectangular flume ...

Abstract: The present study examines the use of pier slots and collars for reducing local scour at bridge piers. The efficacy of slots, of different lengths and at different angles of attack, was studied through experiments. The ...
