Bathymetry used in the simulationThe first two days of November 1999 are simulated to demonstrate the capability of themodel in simulating cycling discharge with dry- and-wet bed conditions. Figure 5 showsthe comparison of simulated and observed water surface elevation at the tailrace alongwith the rating curve. Figure 6 shows the simulated water depth at a low flow (1000 m 3 /s)condition. Figure 7 shows the simulated water depth at high flow (3500 m 3 /s). It can beseen that during low flow, many parts of the river bed, especially at the Rapids, are exposed.The water discharge pattern at the tailrace, i.e. the upstream boundary condition isalso shown in Figures 6 and 7.Tailwater Rating Curve for no ice condition57.00056.000Elevation (m)55.00054.00053.000Observed Dataon Nov.1 toNov. 15, 1999Rating Curvesimulated52.00051.0000.0 1000.0 2000.0 3000.0 4000.0 5000.0discharge (m 3 /s)Fig. 5.
