Document Summary
Energy dissipation structures: introduction, excess energy should usually be dissipated in such a way as to avoid erosion in unlined open channels. Design of small canal structures book by the usbr) In practice, many variations of baffled energy dissipation structures can be found. Side view of a hydraulic jump (flow is from left to right) conjugate depths: the energy loss across a hydraulic jump (upstream to downstream) is equal to the difference in specific energy: E d (1: energy loss can be calculated based on measurements of depth and flow rate. In designs, hydraulic jump energy loss is unknown, so you must apply the momentum function to determine a conjugate depth, then apply eq. )1. 01 (2) where fus is the froude number on the upstream side of the jump: there are several classifications for hydraulic jumps. Donnelly & blaisdell (1965) and involve mostly empirically-determined relationships. In the present context, b represents the width of the stilling basin: note that eq.
