How to Save Selected Nodes and Links in InfoSWMM

Note:   How to Save Selected Nodes and Links in InfoSWMM

Step 1:  Decide what Nodes and Links you want to save.



Step 2:  You can read the flow, velocity, depth and capacity from the RPT Text File.


How to change the Maximum Infiltration in a DB Table of InfoSWMM and H2OMAP SWMM

Note:  How to change the Maximum Infiltration in a DB Table of InfoSWMM and H2OMAP SWMM

There are a lot of methods in InfoSWMM and H20MAP SWMM to change the infiltration data.  You have the ability to change it for

1.      an individual subcatchment using the Attribute Browser
2.      by soil type and
3.      the coverage of the soil over all of the subcatchments – this will alter the areal weighted average of the infiltration data

You have layers of infiltration data in the interface to your model data.  The infiltration parameters are defined per soil as in a real watershed and the subcatchments will use the areal weighted infiltration values of all of the soils on the subcatchment.  You get more flexibility and closer to the physical reality of the subcatchment by having layers of soil on the subcatchment rather than one set of infiltration per subcatchment.  Of course if you set up one soil type per subcatchment then you will have 100 percent coverage of the same infiltration set of parameters per subcatchment.


Method 1: An Individual Subcatchment by using the Attribute Browser



Method 2: All of the Infiltration Data in the Soil Tables using the DB Editor and the Block Edit command.



Method 3:  You can also change the overall Infiltration by changing the soil coverage of the Subcatchment using the Subcatchment Infiltration table.


How to change the background color and data view in InfoSewer and InfoSWMM

Subject:  How o change the background color and data view in InfoSewer and InfoSWMM

Tip 1:  Use the command ViewData Frame Properties > Frame > Background (change color) to change the background color


Tip 2:  Use the command ViewData Frame Properties > Data Frame > Extent to change the default view in Arc GIS.  You would use this tool if you have zoom to a small point in InfoSWMM and InfoSewer.

Steps to take and rules for Cloning Datasets in InfoSWMM and InfoSewer

Note: Steps to take and rules for Cloning Datasets in InfoSWMM and InfoSewer

Before cloning an active dataset, the user should switch to the Base Scenario.  This saves the active datasets and allows the user to clone the dataset with all edits. 


This is a brief description of how datasets are created and saved. 
·         Any data the user changes are only changed in the Active data sets while the user is working in a given scenario. 
·         The modified data are not saved into the selected custom data sets until the user selects different data sets—either by selecting a new scenario or by using the Edit Active Scenario command. 

If the user changes to a new scenario that shares some of the same data sets (e.g. same pipe, valve and pump data sets), the data in these common data sets are still not updated (saved) by changing scenarios.  The user has to actually select a different custom data set of the same type to get the data to update in the custom data set (e.g. the user must select a different pipe set to get the modified pipe data to save into the selected pipe set).  Once created, a dataset is not updated (saved) until it is no longer in use by the active scenario. 



In addition, there is a fundamental difference in between BASE dataset and other dataset(s). 

·         The other dataset(s) must be explicitly created first before they can be used. 
·         BASE dataset will "never" exist until it is switched off from the active scenario. 
·         It gets implicitly created at the first time when it is released from the active scenario.  That is why BASE dataset is never found in a "new" project which has only a base scenario.

How to Make an Internal Outfall into an External Outfall when you have more than one link connected to an Outfall in SWMM5

Subject:  How to Make an Internal Outfall into an External Outfall when you have more than one link connected to an Outfall


Step 1:  Identify the Problem "ERROR 141: Outfall J-561 has more than 1 inlet link or an outlet link." Means you have an outfall node in the middle of your model.


Step 2:  Make a new outfall.


Step 3:  Make the new Outfall  have the same invert as the old outfall 


Step 4:  Convert the older outfall  to a Junction using the Pick Axe and the Convert Type tool


Step 5:  Make a new Link connecting the old and the new Outfall

Step 6:  Convert the new Link to an  Outlet Type using the Convert Type Tool.


Step 7:  Set up the parameters for the new Outlet Link


Step 8:  For those outfalls that DO have more than one link you need to make a new Outfall.




You should be able to run the model now


The Time Base is T + T*K from the Time(T) and Storage (K) values for RDII in SWMM5


Note:  Each of the RDII UH's has a base time for the convolution of the RDII from each UH.  The Time Base is T + T*K from the Time(T) and Storage (K) values  used in the RTK data.  In this particular case:

·         The Fast UH has a time base of 22 hours,
·         The Medium UH has a time base of 430 hours, and
·         The Slow UH has a time base of 4212 hours.

If this is altered as in the  bottom image you can see the difference in the total  RDII I&I Flow

·         The Fast UH has a time base of 22 hours,
·         The Medium UH has a time base of 36 hours, and
·         The Slow UH has a time base of 52 hours.


Four cross sectional areas are used in a link of SWMM 5

Note: Four cross sectional areas are used in a link of SWMM 5. The weighted hydraulic radius (Rwtd) is a function of the Froude Number of the link and the upstream and downstream hydraulic radius.  The Rwtd value is used in the computation of the friction slope or the dq1 term in the file dynamic.c

dq1 = Time Step * RoughFactor / Rwtd^1.333 * |Velocity|

The weighted area (Awtd) is used in the dq2 term of the St. Venant equation:

            dq2 = Time Step * Awtd * (Head Downstream – Head Upstream) /  Link Length

 

Orifice Critical Depth for Separating Weir Flow from Orifice Flow for Bottom Outlet Orifices in SWMM 5

Note:  Orifice Critical Depth for Separating Weir Flow from Orifice Flow for Bottom Outlet Orifices

The Critical height is the opening where weir flow turns into orifice flow. It equals (Co/Cw)*(Area/Length) where Co is the orifice coeff., Cw is the weir coeff/sqrt(2g), Area is the area of the opening, and Length = circumference of the opening. For a basic sharp crested weir, Cw = 0.414.  All of the units are based on the internal SWMM 5 units of American Standard.

For a circular orifice the Critical Height is:

Critical HeightOrifice Discharge Coefficient / 0.414 * Orifice Opening / 4

For a rectangular orifice the Critical Height is:

Critical HeightOrifice Discharge Coefficient / 0.414 * (Orifice Opening*Width) / (2.0*(Orifice Opening+Width))

The Orifice Critical Depth changes dynamically as the orifice is opening and closing for a bottom outlet orifice.  The critical depth separating the orifice weir flow from orifice flow for a side outlet orifice is the height of the orifice.

Link Area Types in SWMM 5, InfoSWMM and H2OMap SWMM

Note:  There are 7 Link flow classification classes that are used to assign the area of the link to the upstream and downstream nodes of the link.  The classes used during the simulation of the model are shown in the Link Classification Table in the RPT Report File.  The supercritical class is the same as the subcritical assignment.  The supercritical is a class of subcritical with a Froude number over 1.

Class

SWMM 5 Pump Curve Head/Flow Curves (1)

Subject:  The Pump flow is based on the lookup table you enter for the pump (Figure 1).  At each iteration during each time step of the solution SWMM 5 will look up the flow for thepump based on the current control variable across the pump.  The control variable for the pump can be one of four variables:

1.   The volume of the upstream wet well,
2.   The depth of water at the upstream node or inlet node without interpolation between data points,
3.   The downstream water surface elevation across the pump minus the upstream water surface elevation, and
4.   The depth of water at the upstream node or inlet node with interpolation between data points.

The pump summary table in the rpt file will tell you how often the pump was used, the maximum flow, the average flow, the total volume of the pump, the power usage and the percent of the time off the entered pump curve.  You can also plot the pump flow versus the inlet depth to see how often the pump was off the pump curve (Figure 2).
