Q. 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 _______
