HYDRAIN - INTEGRATED DRAINAGE DESIGN COMPUTER SYSTEM: VERSION 5.0. VOLUMES I TO VII. FINAL REPORT AND HYDRAIN SOFTWARE DOCUMENTATION

This software documentation report, in seven volumes, presents an integrated system, HYDRAIN, of hydrology and hydraulic computer programs for drainage design and flood computations. Integration of programs is organized around consistent usage of command line input structure or interactive inputs. HYDRAIN is incorporated into the AASHTO Model Drainage Manual, by reference, using detailed example. HYDRAIN software is available through FHWA distribution agents including McTrans Center, University of Florida, Tallahassee, Florida, and PCTrans, University of Kansas, Lawrence, Kansas. This documentation presents technical details of computerized methods, examples, and complete command definitions. The software includes original logic for the programs: HYDRAIN, HYEDT, HYDRO, HYCLV, and HYCHL. The pre-existent programs, HY8, WSPRO, HYDRA, and NFF are adapted to the HYDRAIN system. The seven volumes in this report are as follows: (I) HYDRAIN (system operation, editor usage, files); (II) HYDRO-HYDROLOGY (design flow and rainfall); (III) HYDRA-STORM DRAINS (gravity and pressure flow computations); (IV) HYCLV-CULVERTS (design and analysis); (V) WSPRO-STEP BACKWATER AND BRIDGE HYDRAULICS; (VI) HY8-CULVERTS (analysis and design); and (VII) HYCHL-ROADSIDE CHANNELS (lining design). Training on HYDRAIN is available from National Highway Institute Course No. 13057; training notebook provides supplementary documentation. Minimum equipment and configuration: MS DOS 3.0 or better, IBM XT, 640K RAM, Hard Disk, Monochrome Monitor. Desirable additional equipment: math coprocessor, VGA monitor.
