AcknowledgmentsMaintenance and updating of the EPA SWMM has been continuous since its inception in 1969-70.Over the many intervening years many individuals have contributed to its improvement, notablyEPA colleagues Mr. Richard Field, Mr. Harry Torno, Mr. Chiu-Yuan Fan, Mr. Doug Ammon andMr. Tom Barnwell. Mr. Torno and Mr. Barnwell have also managed the Storm and Water QualityModel Users Group (formerly the SWMM Users Group), a source of invaluable feedback frommodel users, including a large contingent from Canada and abroad.Too many individuals have contributed to specific improvements to list here. This user=s manual,however, is based upon earlier versions to which the following persons contributed significantauthorship while at the University of Florida: Mr. Brett A. Cunningham, Mr. Victor Gagliardo, Dr.Stephen J. Nix, Mr. Donald J. Polmann and Mr. W. Alan Peltz. In particular, Mssrs. Cunninghamand Gagliardo developed the new subsurface routing routine in the Runoff Block. Dr. James P.Heaney has served staunchly as colleague, critic, and pioneer of new ideas. Omission of these namesfrom the current list of authors does not diminish our gratitude for current and past efforts in developingthe model.The Extran Block is one of the most valuable and widely-used components of SWMM. Dr. LarryA. Roesner and Mr. John A. Aldrich of Camp, Dresser and McKee, Inc., one of the three originalSWMM developers, have given generously of their time to enhance Extran and to provide usefulsuggestions for improvements of Extran and the rest of the SWMM model.The Fortran-77 code for Version 4 of SWMM is based on a microcomputer version prepared by Mr.Richard M. Baker and Mr. Karl J. Brazauskas of Metcalf and Eddy, Inc., another one of the originalthree developers. Much of the user’s manual text for Version 4 has been adapted from acomputerized edition of the Version 3 manuals prepared by Dr. William James of Wayne StateUniversity. We are grateful to Dr. James and to Dr. Stephen Nix of Syracuse University for theirhelpful comments regarding Version 4. Assistance in printing of the manuals was provided by KBNApplied Sciences and Engineering, Inc. of Gainesville.At the University of Florida, invaluable word-processing and SWMM dissemination duties havebeen performed faithfully by Ms. Doris Smithson. Main-frame computations were performed at theNortheast Regional Data Center on the University of Florida campus, Gainesville.xxiii
