In addition to the flow of water, a culvert must pass woody debris and sediment and allow passage of aquatic species. If only the design peak discharge is used in the design, the engineer cannot assess what effect increases in the essential design discharge will have on the culvert design. Determine the dimensions of the culvert, including the span, height, and width. Box Culvert - A culvert in the shape of an enclosed rectangle and consisting of a bottom slab, two wall elements and a top slab. Calculate Loads: Oct 7, 2019 · The process of designing a concrete box culvert falls into five steps: Hydrology; Hydraulics; Sizing; Structural design; Headwater is below the culvert crown (culvert is not submerged at Hydraulic Design series No. •Choose culvert material, shape, size and entrance type. 5, No. 3) Side Walls 1. 2) Bottom slab 1. 14m.
