WebJun 6, 2024 · The breach geometry of this control section is assumed to be representative for the entire breach. At the same time it acts only as a hydraulic control section and therefore the location of this transition in flow regime is not relevant for the model (Coleman et al., 2002; Macchione, 2008; Singh, 1996). The energy head is given by WebJan 20, 2024 · Breach widths have been documented in a large number of cases, although predictive correlations are almost nonexistent.
