Fig. 6 Measured bed pressures on the pre-excavated plunge pool (Q100=14,000 m3/s) Fig. 7 Pre-excavated plunge pool in operation (Q100=14,000 m3/s) The mean, RMS fluctuating and extreme peak dynamic pressure coefficients available in the literature for several different jet and plunge pool conditions are shown in Fig.8 and Fig.9. The NT1 plunge pool design flood jet processed data is plotted on the relevant graphs. According to the values shown, it can be concluded that the design flood jet is of a developed one while the plunge pool water cushion regarding the corresponding tailwater level was classified as a “Deep Pool”. This confirms the results of the calculations and classifications of the jet already performed in Section 6. 1038
