Arc Map If Statements for Showing Flooding in InfoSWMM

Arc Map If Statements for Showing Flooding in InfoSWMM

 

You can use a combination of the Map Display in InfoSWMM and the Arc Map Label Properties to show the Maximum Ponded Volume at a node during am InfoSWMM simulation. 

 

The label function in VBSCRIPT to show just non zero flooded volumes(Figure 1) is:

 

Function FindLabel ( [PONDED_VOL] )

If [PONDED_VOL] > 0 THEN

  FindLabel = "" & FormatNumber([PONDED_VOL],2) & ""

END IF

End Function

 

and the values of Flooded Time,  Maximum Flooded Rate and Maximum Ponded Volume can be found in the Junction Attribute Table(Figure 2)  but not the Junction Summary Table of the InfoSWMM output report manager tables. 

 

A VBSCRIPT function to show both ponded volume and flooded rate (Figure 3) is:

 

Function FindLabel ( [PONDED_VOL], [FLOOD_RATE]  )

If [PONDED_VOL] > 0 THEN

  FindLabel = "" & FormatNumber([PONDED_VOL],2) & " / "   & FormatNumber([FLOOD_RATE],1)

END IF

End Function

Figure 2.   If you use the Map Display feature in InfoSWMM then the total flooded time, flood rate and maximum ponded volume will be shown in the Junction Attribute Table.

1000 Year Simulation with Rainfall

Subject:   1000 Year Simulation with Rainfall

 

The attached one Subcatchment SWMM 5 model and associated Rainfall was created using the Random function in Excel on a measured NCD station in Boston.    There is a dry weather flow component of 0.5 cfs with an hourly pattern.  The rainfall averages 54 inches over the 1000 years and the runoff is 20 inches on average over the 1000 years.

Connecting to Others Using Twitter, LinkedIn and Blogs

Twitter besides being 140 characters of greatness has many third party tools such as Tweet Topic Exploreer which allows you to see visually your Tweets by subject, http://tweettopicexplorer.neoformix.com/#n=rdickinson I found it handy to see the interrrelationships of my tweets to each other  and to the industry (Figure 2 and Figure 3).  Here are the Twitter names of myself and Innovyze along with the Innovyze LinkedIn Group:

 

We want to hear from you – connect with Innovyze!

I try to have easy links between Twitter, LinkedIn,  Blogs and Wikipedia on my Ning Social Network, which you can join and post questions and hopefully gather some information (Figure 1)

Advanced SWMM 5 import into InfoSWMM and H2OMAP SWMM

Subject:  Advanced SWMM 5 import into InfoSWMM and H2OMAP SWMM

The current version of InfoSWMM and H2OMAP SWMM not only imports the latest SWMM 5 version but it has built in flexibility that allows the user to import selected data sections, model data sections or auxiliary file information such as calibration data files.  This allows you the choice of importing nonspecific network data that can used in the model of any city, county, shire, town or watershed.  For example,  you can import only these sections without affecting the geometry of your network: 

1.      Calibration File Information,
2.      RTC Rules
3.      Aquifers
4.      Snowpacks
5.      Buildup for Water Quality,
6.      Washoff for Water Quality,
7.      Evaporation,
8.      Time Series,
9.       DWF,
10.        Patterns,
11.        RDII
12.        Loadings,
13.        Curves,
14.        LID Controls,
15.        LID Usage,
16.        Pollutants,
17.        Land Uses

Possible uses of this feature would be to have a city wide or companywide library of LID controls, RTC Rules or RDII values.

InfoSewer to InfoSWMM Import Tips

Subject:   InfoSewer to InfoSWMM Import Tips

 

The direct import of InfoSewer to InfoSWMM (Figure 1) is both direct and robust but you need to be aware of Run Manager changes to optimize the InfoSWMM model:

 

1.       Make sure that the Flow Units in InfoSWMM Run Manager match the default flow units in InfoSewer so that the DWF values are comparable,

2.      Make sure that the Output Flow Units in InfoSWMM match the Output Flow Units in InfoSewer so direct comparisons are easier,

3.      Add a Pump On and Pump Off depth to the Pumps in  InfoSWMM so that the pumps work better in a fully dynamic solution,

4.      The Fixed Pump Curves of InfoSewer should be checked in the Pump Curve section of InfoSWMM to make sure they are comparable,

5.      The InfoSWMM conduit step lengthening option should be used to speed up the model if you have short links in InfoSewer,

6.      You can check the overall balance in the two modeling platforms by comparing the System Load Graph in InfoSewer to the Total Inflow Graph in InfoSWMM.
