The correct choice is (c) 0.96

Easy explanation: The value of Cd varies with different type of bridge openings.

TYPE OF BRIDGE OPENING

VALUE OF Cd

1. Narrow bridge with or without floors

0.94

2. Wide bridge opening with floors

0.98

3. Wide bridge opening with no bed floors

0.96

A road bridge is proposed to be constructed across an alluvial stream with the estimated design discharge as 2500 m^3/s. It is decided to adopt a total effective waterway equal to 300 m for this bridge as against the regime width of 237.5 m due to afflux considerations. If the HFL at the site is at RL 214 m, then the RL of the open foundation can be suggested as _______
