This system can be used to hydraulically design a culvert or hydraulically review an existing or proposed culvert size. The design or review process for drainage culverts is accomplished by routing a hydrograph through the culvert, thereby taking advantage of temporary upstream pond storage. Analysis employing the irrigation design alternative uses only the peak discharge. Various hydrograph relationships, culvert shapes, material, and inlet types can be investigated. The system provides certain environmental and flood hazard data in addition to the culvert hydraulics. The system can be used in any geographical region provided discharges, hydrographs and flood volumes can be identified. Although not part of the system, these practices will aid in identifying any "safety factors" and related cost benefits associated with the culvert design. The system consists of 39 computer programs for computations and plotting and an executive program which controls the flow of the user designated execution of the program segment. All programs are written in FORTRAN IV with the exception of one assembler routine ("GEN4") used in plotting. The plotting programs require either a Xynetics, Calcomp, or similar type of software plotting package.
