Measurement of peak discharge at culverts by indirect methods
George Lawrence Bodhaine
1968, Techniques of Water-Resources Investigations 03-A3
This chapter classifies culvert flow into six types, gives discharge equations based on continuity and energy equations, and describes procedures for measuring peak discharges using culverts in the field. Discharge coefficients for a variety of geometries and flow types arc given. Ten examples detail step-by-step computation procedures....
