Abstract

In this paper, an experimental study was carried out to investigate the characteristics of flow through inclined finite bump in a sloping rectangular open channel of constant width. Experiments were conducted with bed slopes of 0.00, 0.005, 0,010, 0.015, 0.020 and 0.025, and lump angles of 15°, 30°, 45°, 60°, 75 and 90', and relative heights, of 0.1, 0.2, 0.30, 0.40, 0.05 and 0.60 to study the variation of the energy loss and relative water depth with the main parameters affecting the finite hump in sloping channel. These parameters include the channel bottom slope, the upstream Froude number, downstream Froude number, hump angle and relative height. Non-dimensional design curves are provided to relate the flow characteristics. The results show that the rate of variation of the energy loss increases till a finite hump angle of about 30°. This rate of increase decreases behind this value of angle of finite hump. The energy loss increases with the increase of bed slope and relative height ratio. The energy loss is quite high at a relative height of 0.3. The effect of all parameters on the energy loss through the inclined finite hump analyzed and discussed.
