Q full vs Q dynamic vs Q normal
1. It gets more flow than qFull because the water in the pipe has more than just the bed slope to push it – it also has the water surface slope. There is about a 5 meter head pushing the water out if you the bed slope to the water surface slope – see [...]
Future Rainfall
Published: April 2009 Outlook: Extreme As the planet warms, look for more floods where it’s already wet and deeper drought where water is scarce. By Elizabth Kolbert The world’s first empire, known as Akkad, was founded some 4,300 years ago, between the Tigris and the Euphrates Rivers. The empire was ruled from a city—also known as Akkad—that is [...]

SWMM 5 Variable Time Step
Topic: The Variable time step and the Adjustment Factor. The adjustment factor lowers the internal time step used in the model. In the example model the lowering of the Adjustment factor from 75 percent to 25 percent lowers the minimum simulation time step from 20 second to 3 seconds. The inflow and outflow of the [...]

SWMM 5 Complexity Index
SWMM 5 Complexity Index The complexity index for SWMM 5 compares a model to the first Extran example in Extran 3, which would be network #1 in this expanded SWMM 5 network. The baseline network has 22 objects and an 8 hour simulation duration. It took 5 minutes to run this network on a IBM AT [...]
SWMM 5 Pond Infiltration
You can model the pond infiltration indirectly by using either: 1. a Pump Type 4 (the classic SWMM 4 solution to this matter), in which the Pump simulates the pond depth – infiltration rate function, 2. alter the SWMM 5 Evap Factor for a pond so that you have seasonal or monthly variation in your infiltration loss [...]
SWMM 5 Variable Time Step
SWMM 5 Variable Time Step In the SWMM 5 Simulation Options/Dynamic Wave Options is the Variable Time Step Frame which contains the Adjustment Factor Percentage. The Adjustment Factor is a multiplication factor on the CFL condition. The effiect of changing the Adjustment factor can be seen in the following graph. As the value of the [...]
SWMM5 Normal Flow
Option “Define Supercritical Flow By” does inside the SWMM 5 engine. The options are called Slope, Froude and Bothin the GUI and in the engine of SWMM 5. A few other variable definitions you need to know to understand this explanation are: (1) Y1 for the upstream link depth, (2) Y2 for the downstream link [...]
Smaller Storms Drop Larger Overall Rainfall In Hurricane Season
Smaller Storms Drop Larger Overall Rainfall In Hurricane Season ScienceDaily (Dec. 11, 2007) — Researchers have found that when residents of the U.S. southeastern states look skyward for rain to alleviate a long-term drought, they should be hoping for a tropical storm over a hurricane for more reasons than one. According to a new study using [...]

How to Make an InfoSWMM model from the DBF Files
Follow the following steps to create MY .MXD file. 1) Open an empty InfoSWMM project. Do not initialize it. 2) Save the project as MY .MXD within the folder where you have MY. ISDB 3) Initialize the project. 4) Click the reset Display button That should create the project for you. If you want an H2OMAP SWMM project, you can save the [...]

Force Main Transition in SWMM 5
Force Main Transition between Partial and Full Flow 1. If the force main is full then the program will use either Hazen-Willams or Darcy-Weisbach to calculate the friction loss (term dq1), 2. If the force main is NOT full then the program will use Manning’s Equation. // — compute terms of [...]

SCS Rainfall Distributions and Design Storms
SCS Rainfall Distributions for H20MAP and InfoSWMM The base file has a 24 hyetograph for SCS Type 1A and SCS Type 2 distrubutions. The total of the rainfall is 1 inch and to make a 25 year or 50 year storm you follow these steps: 1. Clone the rainfall time series and 2. Use the Field Calculator in [...]
H2OMAP and InfoSWMM Sediment Transport Modeling
H2OMAP SWMM and InfoSWMM Sediment Transport Modeling Sanitary and combined sewer systems can carry substantial loads of suspended solids (waste solids) which can accumulate and cause blockages thereby impairing the hydraulic capacity of the sewer pipes (by restricting their flow area and increasing the bed friction resistance). H2OMAP SWMM and InfoSWMM can simulate the transport and [...]
