| Abstract | ||||
| Sudden load rejection at a hydropower plant causes the development of a positive surge or a hydraulic bore in the power canal. Determination of the bore height and velocity is necessary for the design of the power canal. Determination of these parameters involves the solution of higher simultaneous equations through trial and error procedure which is a laborious and time consuming process, In the present work, a computerized solution of the problem was developed and then a vast data pertaining to the practical range of hydraulic bores was analyzed. As a result, two very useful sets , of three parameter curves were prepared. One of these relates the depth ratios to the Froude number for different discharge ratios . With the help of these charts the depth and velocity of any hydraulic bore can be determined immediately if the initial flow conditions and the dicsharge ratio are known... | ||||
