A Vented Low-Water Causeway: Vent Sizing, Depth Over the Slab, a Closure Rule and What It Gives Up Against a Bridge
Year: 2026
Type: preprint
Abstract: Four 900 mm vents carry 5.43 m3/s after inlet limitation; depth over an 18 m slab reaches 0.30 m at 10.46 m3/s, the closure rule, exceeded an expected 6.3 days per year (98.3 percent passable). Cost 36,060 dollars versus a stated 285,000 dollar bridge, with the losses against a bridge stated in numbers. SIMULATED, NOT MEASURED.
