FLOW MAY OCCUR AS OPEN CHANNEL, <br />GRAVITY FULL OR PRESSURE FLOW <br />. THEORETICAL ANALYSIS IS DIFFICULT <br />. FOR PURPOSES OF DESIGN, STANDARD <br />PROCEDURES AND NOMOGRAPHS ARE USED <br />(SEE HDS-5) <br /> <br />3,2 Culvert Design Approach <br /> <br />A. Flow conditions in a culvert may occur as open-channel flow, gravity full <br />flow or pressure flow, or in some combination of these conditions. <br /> <br />B. A complete theoretical analysis of the hydraulics of culvert flow is time- <br />consuming and difficult. <br /> <br />C. For purposes of design, standard procedures and nomographs have been <br />developed to simplify the analysis of culvert flow. These procedures are <br />detailed in HDS-5, "Hydraulic Design of Highway Culverts." <br /> <br />3.2 CULVERT INLETS <br /> <br />CULVERT INLETS <br /> <br /> <br />. COMMON INLETS INCLUDE: <br /> <br />- projecting culvert barrel <br />- cast-in-place concrete headwalls <br />- precast or prefab end sections <br />- culvert ends mitered to fill slope <br /> <br />3.3a Types of inlets and outlets <br /> <br />3.3b Four Standard Inlets <br /> <br />3-3 <br />
