Figure 2.4.49: Simulated and measured water level atN3 in the second periodFigure 2.4.50: Simulated and measured water levels atN3 in the third periodAs seen from the figure 2.4.49, during the days 19 and 20 when the two dams were close, theestimated water level is higher than the recorded one. Apparently, the actual water flow in thiscondition is lower than the calculated one from water level. It means the employed ratingcurve does not adapt well to this special water regime. Besides, the similarities of measuredand simulated water levels in other simulation times imply the success of model in modellingthe hydrological state of the river system.Figure 2.4.51: Simulated and measured DO at NT1 inthe second periodFigure 2.4.52: Simulated and measured DO at NT1 inthe third periodFigure 2.4.53: Simulated and measured pH at NT1 in Figure 2.4.54: Simulated and measured pH at NT1 inthe second periodthe third period162
