The SWMM 5, 1D Components in InfoSWMM 2D

Note:  The SWMM 5 1D Components in InfoSWMM 2D

The SWMM 5 1D Components in InfoSWMM 2D by dickinsonre Note:  The SWMM 5 1D Components in InfoSWMM 2D InfoSWMM 2D uses standard SWMM 5 components to connect the 1D Nodes to the 2D Mesh.  A bottom outlet orifice at the maximum depth of the node drains to a SWMM 5 Outfall at the fixed elevation equal to the Node Rim Elevation. Flow can go into or out of the Outfall from the 1D element from or to the 2D Mesh. InfoSWMM 2D automatically makes the necessary elements if 2D is used and the new elements are listed in the Hydqua.inp file, which is very similar to the Tab Delimited SWMM5 Input file.  The HYDQUA.inp is very similar to the Excel Tab formatted file of SWMM 5 with a few additional sections and added features: 1st Difference:   The Flood Node Data Section tell the 2D engine which Node has a 1D-2D connection and which 2D mesh element the 1D Node drains to when it is flooded.

How to Compare the Output Manager Statistics in H2OMAP SWMM to the SWMM 5 Output Text File

How to Compare the Output Manager Statistics in H2OMAP SWMM to the SWMM 5 Output Text File by dickinsonre Subject:   How to Compare the Output Manager Statistics in H2OMAP SWMM to the SWMM 5 Output Text File    The value of the total inflow in the text output file is the integrated total for the whole simulation including all time steps.   This is the total volume that is shown in Map Display for Nodes and Links or in the Summary Tables for Nodes and Links.   If you graph the flow or depths in Output Report Manager and use the FieldStatistics tool it will only show you the statistics for the SAVED time steps.  However, if you multiply the Sum (Total) Value by the saved interval in seconds you will have another estimate of the total node of link  statistic.  For example, a Sum Total of L/s times seconds yields liters which divided by 1,000 yields ML.  Figure 2.  Map Display of  the  total link volume in the model run comes from the Node Inflow Summary Table in the Text Report File   ***********************     Node Inflow Summary   ***********************   -------------------------------------------------------------------------------------                                   Maximum  Maximum                  Lateral       Total                                   Lateral    Total  Time of Max      Inflow      Inflow                                    Inflow   Inflow   Occurrence      Volume      Volume   Node                 Type           LPS      LPS  days hr:min    10^6 ltr    10^6 ltr   -------------------------------------------------------------------------------------   PN_060               JUNCTION      0.00     2.93     0  07:47       0.000       0.143 via Blogger http://www.swmm5.net/2013/08/how-to-compare-output-manager.html dickinsonre | August 4, 2013 at 7:28 am | Tags: Blogger, H2oMAP SWMM, IFTTT, InfoSWMM,swmm5 | Categories: H2OMAP SWMM, InfoSWMM, swmm5 | URL: http://wp.me/pnGa9-2wu

Comparison of the H2OMAP SWMM Hazen Williams Force Main Solution to a Steady State HW Solution

Note:  Comparison of the H2OMAP SWMM Hazen Williams Force Main Solution to a Steady State HW Solution

Comparison of the H2OMAP SWMM5 Hazen Williams Force Main Solution to a HW Solution by dickinsonre Note:  Comparison of the H2OMAP SWMM Hazen Williams Force Main Solution to a HW Solution  In this example, we compare the force main head loss in four links in H20Map SWMM to the head loss in a steady state HazenWilliams solution for the same length pipe, diameter and flow (Figure 1).  The H2OMap SWMM model has a large constant dry weather inflow at the wet wells which floods the wet well and causes a constant pump flow to the force main (Figure 2).  TheHW calculator is located here http://www.engineeringtoolbox.com/william-hazens-equation-d_645.html and a comparison forHW head loss in PSI for 5000 feet long, 3 inch diameter pipes with HW Coefficients of 130, 120, 110 and 100, respectively, is shown in Table 1.   The SWMM 5 equation loss (PSI Diff) and the PSI loss from the HW calculator are very close for all four links.   Table 1.  Steady State comparison between HW Calculator and H2OMAP SWMM/SWMM 5 Force Main calculations.  HW SWMM5 SWMM5 SWMM5 Loss Loss  Coefficient Psi UP PSI Dn PSI Diff PSI HW Calculator 130 84.563 44.88 39.683 39.82 120 88.772 43.765 45.007 45.16 110 91.798 41.426 50.372 50.54 100 95.354 38.727 56.627 56.82  Figure 1.   H2OMAP SWMM Wet Well, Pump, Force Main and Gravity Main Network  Figure 2.  Constant Pump Flows   via Blogger http://www.swmm5.net/2013/08/comparison-of-h2omap-swmm5-hazen.htm

How to Calculate the Freeboard of a Node in InfoSWMM/H2OMAP SWMM from the Model Results

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 Information DB Table and paste the Freeboard from Excel.  You will be able to perform Map Displays or Map Queries now using the new Freeboard information column.  via Blogger http://www.swmm5.net/2013/08/how-to-calculate-freeboard-of-node-in.html
