How to Divide the Inflow at a Node in InfoSWMM by dickinsonre Subject:  How to Divide the Inflow at a Node in InfoSWMM In SWMM 5 only the Kinematic Wave solution allows a flow divider at a node to divide the Inflow to node to two  downstream  links, but you can use the Inflow/Outflow Outlet type in InfoSWMM to divide the inflow based on a Inflow/Outflow Diversion Table (Figure 1).  For example, in InfoSWMM it is possible to have two downstream links from a Node that are Outlet types Inflow/Outflow so that the low flow goes down one link and the high flow goes down the other link (Figure 2 and Figure 3).   The low flow and the high flow  link  use different diversion tables in which the tables are constructed so that the flow is positive in one link and zero in the other to a dividing flow value and then zero and positive for the same two links after the dividing flow value ( 5 cfs in the example).  Figure 1.  Types of OUTLETS in InfoSWMM and SWMM 5 Figure 2.  Example low flow and high flow Outlet Links to divide the total  inflow at the upstream node at 5 cfs.  Figure 3.   The flow is divided into the low and high flow links at the dividing flow of 5 cfs.  via Blogger http://www.swmm5.net/2013/08/how-to-divide-inflow-at-node-in-infoswmm.html

Drawing features to show multiple attributes in InfoSWMM and InfoSewer by dickinsonre Subject:   Drawing features to show multiple attributes in InfoSWMM Your network data usually has a number of different attributes that describe the features it represents (Figure 3). While you'll commonly use one of the attributes to symbolize the data—for example, showing one quantity in the InfoSWMM Map Display —you may sometimes want to use more than one.   One way to show multiple attributes inInfoSWMM is to copy layers and then use the Layer Properties to color, map or otherwise display the multivariable data (Figure 1).  For example, Figure 2 shows the important Subcatchment parameters of Slope, Imperviousness and Width as graduated colors, dots and a pie shape, respectively.  Figure 1.  Use the Symbology Tab to select the attribute you want to show and the way to show the attribute.  Figure 2.   The Subcatchment slope is shown in graduated colors, the percent impervious in scattered dots a a measels map and the Subcatchment Width is shown in a pie graph with the size of the pie a function  of the total  width.  Figure 3.  Physical Data Estimated from a DEM using the Subcatchment Manager in InfoSWMM. via Blogger http://www.swmm5.net/2013/08/drawing-features-to-show-multiple.html

Create Watershed Data Using InfoSWMM Subcatchment Manager

Subject:  Create Watershed Data Using InfoSWMM Subcatchment Manager

The Subcatchment Manager of InfoSWMM will  help calculate most of the  physical parameters associated with a Watershed or Subcatchment in SWMM 5 from a Digital Elevation Data (Step 1).  The Subcatchments slope is estimated from a slope raster (Step 2) and the Slope Calculator (Step 4). The created watershed area are calculated using the command Update DB from Map (Step 6) along with the Subcatchment Width (Step 3) and the Impervious Area (Step 5).   The physical parameters estimated from the DEM are shown in Figure 1.

Figure 1.  Physical Data Estimated from a DEM using the Subcatchment Manager in InfoSWMM.

Step 1.  Use the command Create Flow Stream to create a Flow Stream for the DTM or DEM that can be used later.

Step 2.   Create a Slope Raster from the DEM for later usage in the Slope Calculator.

Continuous Simulation Aids for InfoSWMM

Subject:   Continuous Simulation Aids for InfoSWMM

If you have a large network and especially if you are doing continuous simulation then you want to have many tools for helping you understand the network and the simulation results.  

v  In InfoSWMM and H2OMAP SWMM you can have a Base Network with many differenct Child Scenaio generations.  A Child can be either based on the Base Scenario of a different generation Child Scenario.

v  Facility Manager allows you to make inactive and active sets areas of your network, which makes simulating larger and smaller models a snap to do in InfoSWMM.   Run Manager lets you control which areas of the model  network gets save to the  binary graphics file (Figure 1). 

v  The Process Control in  Run Manager (similar to the process control in SWMM 5) allows the modeler to control  which processes are simulation to  help in her model  calibration.

RDII or Tri Triangular Unit Hydrograph in InfoSewer

Subject:  RDII or Tri Triangular Unit Hydrograph in InfoSewer

RDII or Tri Triangular Unit Hydrograph in InfoSewer by dickinsonre Subject:  RDII or Tri Triangular Unit Hydrograph in InfoSewer The RDII method in InfoSewer is similar to the RDII or RTK  method in  InfoSWMM with some differences.    The RTK data for triangles 1, 2 and 3 are defined in the Unit Hydrograph but instead of individual R values, the overall R is set and the Percent R1,  R2 and R3 are defined based on the total  R.  R3 is calculated internally as 100 – R1 – R2.   Each loading manhole with RDII flow has a total  area, a hyetograph and a Unit Hydrograph.  The hyetograph has to be set at multiples of the unithydrograph, so you can define the time or X columns with integers and then use the Block Edit command to change X to minutes by multiplying  by the Unit Hydrograph time (Figure 1).   You can use only one component if you set R1 or R2 to 100 percent or R3 to 100 percent by setting R1 and R2 to 0 percent (Figure 2).  The overall area of the Unit Hydrograph is divided amongst the loading manhole using the Subbasin Area (Figure 3).   The storm flows generated can be viewed using a Group Graph (Figure 4).  Figure 1.   Hyetograph Curve for the RDII Unit Hydrograph    Figure 2.  The Unit Hydrograph is defined for various values of R, R1,  R2, T1,  T2,  T3, K1,  K2 and  K3.  Figure 3.  The Unit Hydrograph and Hyetograph are tied to a particular loading manhole using a Subbasin Area.

How is the Maximum Link Flow Applied in SWMM 5?

Subject:  How is the Maximum Link Flow Applied in SWMM 5?

How is the Maximum Link Flow Applied in SWMM 5? by dickinsonre Subject:  How is the Maximum Link Flow Applied in SWMM 5? The maximum flow limit for a link applies to the kinematic wave and the dynamic wave solution.   The inflow to the link  in the kinematic wave solution is limited (Figure 1) but the calculated link flow is limited in the dynamic wave solution after the link flow (Figure 2): 1.       Is checked using the Culvert Inlet Equations (optional) 2.      The normal flow equation is checked (internally optional depending on the Normal flow options) and 3.      The Picard iteration solution under relaxation parameter (always 0.5) is applied (Figure 3). Figure 1.  Kinematic Wave Solution Limits the Inflow to  the Link Maximum limit. Figure 2. Dynamic Wave Solution link  flow limit. Figure 3.  The Link  flow in the dynamic wave solution has three checks at each iteration in a time step. via Blogger http://www.swmm5.net/2013/08/how-is-maximum-link-flow-applied-in.html

Adverse Slope Convention in SWMM 5

Subject:  Adverse Slope Convention  in  SWMM 5

If the slope of a link  is negative and the solution  is dynamic wave then the following data will be switched in link.c in SWMM 5.  All upstream data for the  link  is switched to the downstream end of the link  and  vice versa.   The means that if the flow  is from the original upstream node to the downstream node the flow  will  be negative in the output of  SWMM 5. 

Negative flow in SWMM 5 means:

1.   The link has an adverse or negative slope,
2.   The link  has reverse flow if the link slope is positive.
