Note:    How to Calculate the Freeboard of a Node in InfoSWMM/H2OMAP SWMM from the Model Results How to Calculate the Freeboard of a Node in InfoSWMM/H2OMAP SWMM from the Model Results by  dickinsonre Note:    How to  Calculate  the  Freeboard  of a  Node  in  InfoSWMM / H2OMAP   SWMM  from the  Model   Results   The  freeboard  for a  node  in  InfoSWMM / H2OMAP   SWMM  can be calculated with a 4 step process:   1.    Copy the  Node  Rim Elevations from the DB Tables for Junctions to Excel, 2.    Run the  model  and then copy the Maximum HGL from the Junction Summary output table to Excel, 3.    Calculate  the  Freeboard   in Excel as the Rim Elevation minus the Maximum HGL in Excel, 4.    Create a new column called  Freeboard  in the Junction Inform...

Node Comparison in InfoSWMM and InfoSewer by  dickinsonre Note:    Node   Comparison  in  Info SWMM  and  InfoSewer   1)    Is there an option to set the manhole sealing method (i.e. locked  or unlocked) in  InfoSWMM ?  You set the Surcharged depth to a positive value to prevent flooding and keep the pipes under pressure.  You will still have flooding once the water surface elevation reaches the maximum depth + surcharge depth.  Unlike in InfoSewer  the depths are not unlimited.   2)       Is defining manhole diameter in   InfoSWMM   available?     You can set the default surface area of a   node   or make it a storage node .       3)       Does   InfoSWMM   allow me to create parallel pipes with the same   attributes similar to  InfoSewer ?  You can set t...

Subject: InfoSewer and H2OMAP Sewer New Features in 2011 InfoSewer and H2OMAP Sewer New Features in 2011/2013 by  dickinsonre Subject:   InfoSewer  and  H2OMAP   Sewer   New   Features  in  2011/ 2013 InfoSewer  for Arc GIS 9 and 10 and   H2OMAP   Sewer  had a many engine and GUI enhancements during  2011  to allow the programs to work better for models up to 50,000 elements that simulate water quality and hydrology.  The improvements now allow large models to be run with smaller report and simulation time steps and provide a Mass Balance Check  at the end of the report file for the user to easily check the model results.  The  new  ForceMain  Solution for EPS simulations now allows the simulation of complicated Force Main Loops in the network without the need for making simplifying network connection assumptions.  The engine changes make  Inf...

Subject: Pump Volume per Pump Event in SWMM 5 Pump Volume per Pump Event in SWMM 5 by  dickinsonre Subject:   Pump Volume per Pump Event in SWMM 5   You can calculate the  volume   per  startup  event   by using the  Pump  Summary Table in  SWMM   5  and copying a few columns to Excel.        1.    Go to the  Pump  Summary 2.    Copy  Pump  Name, Total  Volume  and  Pump  Startups to Excel 3.    Divide to get  Pump   Volume   per   Event   You will now have the average  volume   per   event .

Subject:  Qfull in SWMM 5 for various levels of y/yFull in a Circular Pipe Here is a table that shows the value of Q/Qfull for various levels of y/yFull or d/D in SWMM5.  The full flow if you loop off the top of a circular pipe at the 0.83 level would be about 1.01 times Qfull for the whole pipe.  Figure 1 shows how the flows are calculated at various values, Table 1 and Figure 2 show the values of a/aFull, r/rFull and q/qFull for various values of y/yFull. Figure 1 .   How Qfull and Qmax are calculated in  SWMM 5 based on the roughness, slope and a lookup table for area and hydraulic radius for a circular pipe. y/yFull a/aFull r/rFull Q/qFull 0.00000 0.00000 0.01000 0.00000 0.02000 0.00471 0.05280 0.00066 0.04000 0.01340 0.10480 0.00298 0.06000 0.02445 0.15560 0.00707 0.08000 0.03740 0.20520 0.01301 0.10000 0.05208 0.25400 0.02089 0.12000 0.06800 0.30160 0.03058 0.14000 0.08505 0.34840 0.04211 0.16000 0.10330 0.39440 0.05556 0.18000 0.12236 0.43880 0.07...
