Preparation of input data for automatic computation of stage-discharge relations at culverts

摘要: Detailed instructions are given on the preparation of input data for automatic computation stage-discharge relations at culverts. The program follows standardized methods computing headwater elevations, discharges, tailwater and geometries approach cross section culvert. basic energy equations programed solutions singlebarreled circular pipes, riveted or multiplate pipe-arches, rectangular box culverts with without webs. A full relationship can be developed range discharges elevations selected. option that is independent culvert discharge used to obtain properties either a defined channel section, both barrel. One example demonstrates technique.
