Paper Title
Turbulence Characteristics And Velocity Response In An Open Channel Using Acoustic Doppler Velocimeter
  Akshaye,  Mohit kumar

In this experimental study, efforts have been made to know how the sudden change in bed roughness affects the flow parameters, the series of experiments were performed in a rectangular hydraulic flume. The hydraulic flume was 3.47 m long, 0.622 m wide and 0.535 m deep. Four different kinds of roughness was generated, each of length 0.63 m and 0.621m wide. The average height of roughness 13.5 mm, 28.5mm, 46.5 mm and vegetated mat were used to generate the roughness. Acoustic Doppler velocimetre were used to find the velocity at each depth in the rectangular flume. The discharge was found with the help of sharp crested wear located at the downstream of the hydraulic flume. The observations were taken for the sudden change in the bed roughness. The observed velocity distribution for sudden change in the bed roughness was compared and analyzed. A new correlation is proposed that will help in better estimation on the effect of flow parameters due to a sudden change in bed roughness which ultimately will help in designing more efficient channel section and improving the economics of channel design.

Keywords- acoustic doppler velocimeter, sudden change in bed roughness
