Fig. 6.46 Scenario (3); simulation results of velocity (m/s) and depth of water (m), food 1957;
(modeling with considering the dyke)

Comparing the estimated depth and velocity in 1957, the effects for scenario (4)
were much more disastrous than in the cases of scenario (1). For this scenario, the
same river morphology was assumed as applied for scenario (1). As can be seen in
the results obtained from scenario (4) the dykes overtopped on several sections in
both banks, especially in the urban sectional area. Critical overtopping occurred
