How to Create an InfoSWMM model
An InfoSWMM model can be newly created from a CSV file but it helps to have an idea of the maximum extents before you initialize the Arc Map project. Use the ArcGIS default and Edit the extents of your future imported network (Figure 1). Import the CSV files (Figure 2) and define the imported variables (Figure 3) followed by an Update Map from DB (Figure 4) which will draw your imported nodes and links on the Arc Map screen. The updated Map should be within the extents of your defined spatial reference (Figure 5). It is important to have the proper spatial reference for your imported data in Arc Map. If you do not have the proper extents then when you update the Map from DB you will have a warning message "The coordinates or measures are out of bounds".

How to Create an InfoSWMM model
An InfoSWMM model can be newly created from a CSV file but it helps to have a background map or shapefile to initialize the Arc Map project. BEFORE initializing yourInfoSWMM map Add a data layer using the Arc Map command Add Data. Create a new InfoSWMM project using the same spatial reference as your added shapefile (Figure 1). Import the CSV files (Figure 2) and define the imported variables (Figure 3) followed by an Update Map from DB (Figure 4) which will draw your imported nodes and links on the Arc Map screen. The updated Map will have the same coordinates as the background shapefile (Figure 5). It is important to have the proper spatial reference for your imported data in Arc Map.

How to Save Node and Link Relates in H2OMAP SWMM to Shapefiles
How to Save Node and Link Summary Tables in H2OMAP SWMM to Shapefiles
How to Save Node and Link Summary
The export manager of H2OMAP SWMM is very flexible, you can export shape, MIF and CSV files but you have to do some copy and pasting to allow the program to export ALL of the node and pipe summary tables. The export manager will export any node or pipe information in the DB hydraulic and information tables. If you copy and paste, for example, the output pipe summary table to the Pipe information tables (Figure 1) then you can use the Export Manager (Figure 2) to save the shape file with tables(Figure 4) and view the shape file in Arc Map (Figure 4). The TOC properties in Arc Map can be used to show the maximum d over D or maximum Q over Qfull values in Arc Map using this VBScript.
Function FindLabel ( [DOVEMAXD] )
FindLabel = "" & FormatNumber([DOVEMAXD],2) & ""
End Function

Annual International Conference on modeling urban water systems, Feb 21-22 2013 in Toronto - call for papers
Annual International Conference on modeling urban water systems, Feb 21-22 2013 in Toronto - call for papers
My note, this is a conference well worth attending, the Convenor is Dr Bill James and the venue is described at the CHIWater link shown below.
Once again it's the time to request one or more abstracts for the Annual International Conference on the Modeling of Urban Water Systems (formerly SWMM users meeting), to be held Feb 21-22 2013 in Toronto (note the venue). As you probably know, this is the 46th (!) meeting in this extraordinary series. This year our featured speakers include many well-known scientists, researchers and engineers (listed on our website).The meeting is well attended: your audience exceeds 100 folks in your specialty. Also, the meeting is inexpensive, highly-regarded, professional, friendly and collaborative. Proceedings are produced as a peer-reviewed, integrated archival-quality book (you get the previous year's monograph at this conference, two-for-one value). The conference addresses all aspects of urban water systems, including planning, design, construction, operation, monitoring, models, safety, and security; how to manage urban water systems including water supply, drainage, pollution control, domestic, municipal, and industrial waters and stormwater from surface water catchments or ground water; and real-time control along with education, outreach, and practical applications. We welcome abstracts in any and all of the following general categories:; LIDs and BMPs; TMDLs; Urban water disasters, Urban flood management, Land Use; Nonpoint Sources of Pollution; Pavement; Pathogens; Stormwater and Urban drainage; Potable Water Supplies; Water distribution; Water System utilities; and other management and socio-political issues. Although the discussion is generally technical, it meshes well with management and difficult topics connected to urban water and related to computer modeling. Please visit:
http://www.chiwater.com/Training/Conferences/conferencetoronto.asp
Please email your 1-page abstract(s) to me in the next week or so. Alternatively, if you need a more formal invitation or a flyer, let me know. We look forward to seeing you and your colleagues in Toronto - you won't get a better deal in these economically-challenged times!

How to Use Two Control Curves in SWMM 5 to Simulate a Head Difference Rule
Subject: How to Use Two Control Curves in SWMM 5 to Simulate a Head Difference Rule
Subject: How to Use Two Control Curves in SWMM 5 to Simulate a Head Difference Rule
The SWMM 5 control rules for Real Time Control (RTC) do not allow the rule to be governed by the head across the orifice but does allow rules based on the depth, head and inflow at any node. If you have an Orifice in which you want the Orifice to be open when the head difference across the Orifice is either less than or greater than zero then and closed when the head difference is close to zero then you can use two Orifices (Figure 1) and two rules (Figure 2) to control the orifice setting for Orifice1 and Orifice2. In attached file the two rules have the settings set to two control curves. Orifice1 will start open and close gradually as the depth at Node UPNode increases, Orifice2 will start closed and gradually open when depth in Node DNode increases. Possible variations are to control Orifice1 based on the DNode and node UPNode to control Orifice2.
RULE Orifice1
IF NODE UPNode Depth >= 0
THEN ORIFICE ORIFICE1 SETTING = Curve RuleOrf1
PRIORITY 10
RULE Orifice2
IF NODE DNode Depth >= 0
THEN ORIFICE ORIFICE2 SETTING = Curve RuleOrf2
PRIORITY 10

NASA computed Maps of Earth
NASA computed Maps of Earth
Die NASA hat sich ‘nen neuen Supercomputer angeschafft und simuliert mit dem die Erde, heraus kommen zum Beispiel so schicke Karten wie das Ding oben, und das Teil ist keinFoto, sondern ‘ne berechnete Grafik. Whoa!
This is not a photo of the Earth from some far-flung satellite. This is the output of a computer that has been programmed to take those laws of physics and apply them to the Earth. It has data about sunlight hitting the Earth (which includes variations for season); it knows about the composition of the Earth’s atmosphere and how the air’s temperature changes with latitude, longitude, and height; it can calculate how much water evaporates and where it rains or snows out; it accounts for fires, dust, the Earth’s rotation, the local geography, and even humanity’s effect on the environment.And when it’s done, it can show us what the Earth looks like under various conditions. In this case, the blue swirls over the oceans trace sea salt; green is smoke from forest fires, white is sulfate particles (emitted from volcanoes and the burning of fossil fuels), and reddish-orange is dust blown about.

How to Use the Map Display for the Maximum Adjusted d/D or Maximum q/Q in an EPS InfoSewer Simulation
How to Use the Map Display for the Maximum Adjusted d/D or Maximum q/Q in an EPS InfoSewer Simulation
How to Use the Map Display for the Maximum Adjusted d/D or Maximum q/Q in an EPS InfoSewer Simulation
You can do a Map Display of the adjusted d/D values (Figure 1) from the Gravity Main Range Report (Figure 2) to show those pipes that are full thematically. For example, the links in red in Figure 1 show the effect of the pump blockage and the links in green are those NOT full due to the pump blockage. You will need to copy the adjusted d/D or the maximum q/Q values from the Range report to the Link Information Table to have some values to Map (Figure 3 and 4). The maximum adjusted d/D or the Maximum q/Q can be mapped using the new link information (Figure 5).

What are the LID Control Flow Source Options in SWMM 5?
What are the LID Control Flow Source Options in SWMM 5?
The SWMM 5 options for Low Impact Development (LID) controls on a Subcatchment are very flexible, exciting, possibly recursive and a completely integrated method to treat both the pervious and impervious flow. You can send the Subcatchment runoff to either an outlet node, impervious area of the Subcatchment, the pervious area of the Subcatchment or another Subcatchment. You can have the LID control receive a portion or all of the impervious flow OR as in the EPA SWMM 5 LID example have the LID cover the whole Subcatchment and receive both impervious and pervious flow from one or multiple upstream Subcsatchments. For example, Subcatchment Swale4 in Figure 1 is 100 pervious and has upstream runoff from the pervious and impervious areas of Subcatchments S1, S3 and S4 in Figure 1. The LID can also have either an outlet node or the pervious area of the Subcatchment on which it resides.

Inflow Time Series in InfoSewer
This is how InfoSewer can use a time series of inflow at a specific node:
1. Use a mean loading of 1 so that the values in the Inflow Time Series stay the same as your inflow units in InfoSewer (Figure 1)
Figure 1. Load with a Pattern of Inflow will create a loading to the node based on your inflow time series.
2. Create a PATTERN that is equal to your inflow time series
3. The pattern has to have the same time steps as your default Run Manager Pattern option, normally this will be one hour
4. The factor column is your inflow in cfs, gpm, lps or mgd (Figure 2)
Figure 2. The Inflow Time Series Pattern is your Flow
5. The Base Load should equal your Inflow Pattern (Figure 3)

How are Flooded Time, Surcharged Time and Flooded Volume Calculated in InfoSWMM and H2OMAP SWMM?
How are Flooded Time, Surcharged Time and Flooded Volume Calculated in InfoSWMM and H2OMAP SWMM?
How are Flooded Time, Surcharged T
The time, volume and flooded
For All Nodes NOT Outfalls ( this includes Junctions, Storage Nodes, Dividers)
If the New Volume is greater than the Full Volume of the or there is Overflow then at each time step the Time Flooded is increased
If the New Volume is greater than the Full Volume of the or there is Overflow then at each time step the Volume Flooded is increased by the Overflow *Time Step
If the New Volume is greater than the Full Volume of the or there is Overflow AND Surface Ponding is Used then the Ponded Volume is New Volume – Full Volume
If the Node Depth Plus the Node Invert Elevation is above the Node Crown Elevation then at each time step the time surcharged is increased. The InfoSWMM andH2OMAP SWMM
