CSV File DWF Suggestion for Importing SWMM5 Flows to ICM

If you are importing a SWMM 5 File into InfoWorks ICM one problem you will have how to deal with difference in dry weather flow generation (DWF):

1. SWMM 5 has DWF enter at a node and ICM has DWF as part of the Subcatchment Loading
2. Thee Import and Export From ICM needs manual adjustment of the DWF
3. One way to do this is to make an ICM CSV file to import the DWF Section of SWMM 5 (Figure 1)
4. Which allows you to manipulate the flow DWF in SWMM 5 to the population based DWF in ICM and IWCS.

Here is one example
ObjectTable,subcatchment_id,population
hw_subcatchment,  S012-010 ,4.14841
hw_subcatchment,                   S005-005#1,7.8094
hw_subcatchment,                   S005-006#1 ,7.8094

Introduction to Running SWMMLive from @Innovyze

Introduction to Running SWMMLive from @Innovyze

A new product from Innovyze is SWMMLive which combines our InfoSWMM or H2OMap SWMM engine with the power and features of ICMLive and the ICM Interface.  This will be a continuation of my blogs on SWMMLive and for this blog we will discuss the basics of getting an InfoSWMM model to run in SWMMLive.   The 1^st step is to use the Add On extension in InfoSWMM and H2OMap SWMM from the tools menu (Figure 1).  This will start the SWMMLive Manager where you can export your InfoSWMM or H2OMap  SWMM model to SWMMlive (which is a different Innovyze product) and Diagnose the SWMMLive Model if needed (Figure 2).    Once you have exported the InfoSWMM model then you can import the model to SWMMLive as the network in the Live Group of your Master Group (Bullet 1 in Figure 3).   You run the model using the ICM like Run Manager but using the InfoSWMM engine (currently based on SWMM 5.0.022) as you can see in Bullet 2 of Figure 3.    You can run multiple scenarios in a run (Bullet 3 in Figure 3) along with many of the ICMLive features such as Ground Tin's,  Queries,  Spatial Databases and Selection lists (Bullet 4 in Figure 3).   Once you run the model you can use the ICM tools to select (Bullet 5),  Select (Bullet 6) and View the Graphs or Grid Views (Bullet 7).  In the next blogs we will show how to set up Alerts and Other More Advanced Features.

How an Inflow Time Series is Used in ICM compared to SWMM5 using H2OMap SWMM and InfoSWMM

How an Inflow Time Series is Used in ICM compared to SWMM5 using H2OMap SWMM and InfoSWMM.  The main points are illustrated by blue bullet points in Figure 1.  ICM and SWMM 5 both use time series but in SWMM 5 one time series can be applied to multiple nodes.

1. Inflow Time Series Name uses a CSV file
2. The CSV file has time rows, flows for the number of nodes with inflow and column headers with the names of the nodes,
3. InfoSWMM, H2OMap SWMM and SWMM 5 have a user defined time series at loading nodes in the Inflow Icon,
4. A time series is used as the source of flow and the time series can be the same for multiple nodes.

@Innovze has RDII Flow at the Subcatchment Level in ICM and IWCS and at the node level in InfoSWMM and H2OMap SWMM.

How to Make a Selection Set from the ICM Compare Command

How to Make a Selection Set from the ICM Compare Command

The Steps are:

1.       Use the Compare Tool to compare two Networks
2.      Save the Compared Items to a CSV File
3.      Copy the Node and Links that are different in Excel from the CSV File
4.      Make a Selection Set
5.      Copy the Node and Link ID Names to the Selection Set

How to Define Green Ampt Infiltration in ICM

Here are the steps to make a Subcatchment with Green Ampt Infiltration in ICM:

1.       You use the Subcatchment, Land Use and Runoff Surface Tabs in the Subcatchment Grid (Bullet 1)
2.      The Subcatchment Tab has three Runoff Areas for Impervious with Depression Storage or Initial Loss, Impervious with no Initial Loss and Pervious Area (Bullet 2)
3.      The Runoff Surface percentages on the Subcatchment are connected to the Land Use Tab by the Land Use ID, in this example we are using Runoff Surfaces 22, 23 and 24 (Bullet 3)
4.      The Runoff Tab defines the Runoff Surfaces defined in the Subcatchment Tab and Land Use Tab (Bullet 4)
5.      You can define the Routing Model per Runoff Surface or SWMM in this case (Bullet 5)
6.      The type of Runoff Surface and Surface Type for each Runoff Surface or GreenAmpt for Runoff Surface ID of 24 (Bullet 6)
7.      The Depression Storage or Initial Loss Value for each Runoff Surface in the Runoff Surface Tab (Bullet 7)
8.     The Green Ampt Infiltration Parameters are defined to the right in the Runoff Surfaces Tab (Bullet 8)

a.      Suction in inches or millimeters

b.      Saturated Hydraulic Conductivity in inches/hour or mm/hour

c.       Deficit as a fraction
