This manual is a practical application guide for new SWMM users who have already had some previous training in hydrology and hydraulics. Therefore, it is necessary to know the large drainage capacity that is able to accommodate the amount of runoff discharge when the rain occurs using the 5-year return EPA SWMM software modeling. The EPA Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model that computes runoff quantity and quality from primarily urban areas. The flooding that occurred in this area caused several schools, offices and hospitals to be flooded, a number of houses and a number of points on the local road were flooded. The cause of inundation in this area is that drainage is not able to accommodate water and high rainfall intensity with the parent river in the Batang Kuranji watershed. This area is a densely populated area (1,000 people / km 2). Based on the news collected from 2009–2018, it was found that Gunung Pangilun Village, Padang Utara Subdistrict was often flooded when it rained for more than 3 hours. NVivo software is utilized to analyze the online news which reported floods occurrence. The zipped file contains the self-installing program, support files, example files, and release notes. SWMM5 (version: 5.1.009) SWMM5 is public domain software by the EPA (From the EPA site: 'Storm Water Management Model (SWMM) is used throughout the world for planning, analysis and design related to: stormwater runoff, combined sewers, sanitary sewers, and other drainage systems in urban areas with many applications in non-urban. This version is the official release of the older SWMM4 program, but it's somewhat out of date. It would benefit you to read them (if you have not already downloaded the PDF files).Floods have often occurred in the city of Padang, PALAPA Metropolitan Urban Area in recent years, this is generally caused by high rainfall and poor drainage capabilities. SWMM 4.3 1994.05 - Official US EPA version. It is truly an outstanding aid to modelers and modellers worldwide. The documentation is fantastically complete with detailed background on the theory, process parameters and completely worked out examples for all of the processes in SWMM5. I have noticed based on email questions and postings to the SWMM LIst Sever (a great resource hosted by CHI, Inc.) that many SWMM 5 users do not know about the really outstanding documentation on SWMM 5 posted on the EPA Website It consists of two now and in the near future three volumes on Hydrology, Water Quality, LID’s and SuDs and Hydraulics. I posted this on the SWMM Group on LinkedIn World Class Software Documentation for SWMM5 from Lew Rossman and Wayne Huber (Hydrology) Autodesk Inc bought Innovyze Inc on 4/2021 so I have multiple work emails now. You can send me an email to or or and I will do my best to answer your questions.
