How to determine culvert size
WebThe equivalent diameter of a rectangular tube or duct can be calculated as (Huebscher) de = 1.30 (a b)0.625 / (a + b)0.25 (1) where de = equivalent diameter (mm, inches) a = length of major or minor side (mm, inches) b = length of minor or major side (mm, inches) WebThe following equation is used to determine the Apron rock size, D50: Where: D50 = required riprap size in ft (m) Q = discharge in cfs (cms) D = culvert rise (diameter) in ft (m) Tw = tailwater depth in ft (m) g = acceleration due to gravity Tailwater depth is limited to between 0.4D and 1.0D. For example, if Tw is less than 0.4D then Tw = 0.4D.
