9.2.8. Location of Hydraulic Jump on Glacis It is generally assumed that the jump forms at the junction of the glacis with the horizontal floor and, therefore, the relations for classical hydraulic jump are used for determining the location of the jump on glacis. For known discharge intensity q, and the difference in the levels of the upstream and downstream levels of total energy line, ∆E, one can determine the downstream specific energy, E2, using a suitable method or Blench’s curves (Fig. 9.17). The location of the jump on a glacis can then be obtained by finding the intersection of the glacis with the horizontal plane E2 below the downstream level of the total energy line.
