A road bridge is proposed to be constructed across an alluvial stream with the estimated design discharge as 2500 m³/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 _______

1.	A road bridge is proposed to be constructed across an alluvial stream with the estimated design discharge as 2500 m³/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 _______
A.	206.6 m
B.	208.5 m
C.	207.2 m
D.	210.2 m
Answer» B. 208.5 m
