This project report, in six volumes, documents a system of computer programs oriented to the design of drainage components: culverts, storm drains, and open channels. The system includes an input generator to estimate design rain, hyetographs, design flow and hydrographs at user selected return periods. Programs are facilitated with semi-expert system shells that generate input data for engineering programs. All system elements fit into an open architecture that utilizes personal computers having hard disks, math coprocessors and operate within an MS-DOS environment. This volume, Volume III, documents PFP-HYDRA, which is a storm drain analysis and design program. This report is intended to introduce PFP-HYDRA and guide the user through the necessary steps toward designing or analyzing stormwater drains and/or sanitary sewer systems. In the PFP-HYDRA design process, the program will select the pipe size, slope and invert elevations if given certain design criteria. Additionally, PFP-HYDRA will perform analyses on an existing system of pipes (and/or ditches).
