Subject:   H2OMAP Sewer and InfoSewer Water Quality Options
H2OMAP Sewer and InfoSewer Water Quality Optionsby dickinsonre Subject:H2OMAPSewer and InfoSewerWaterQualityOptions You can model 8 options in H2OMAPSewer and InfoSewer to simulate various aspects of WaterQuality (Figure 1).  If you make the base scenario no waterquality you can have the same network, same loading but different aspects of waterquality in seven child scenario's (Figure 2).  The parameters for each waterquality option is shown in the Quality Tab of the SimulationOptions Dialog.

Note:  The SWMM 5 1D Components in InfoSWMM 2D The SWMM 5 1D Components in InfoSWMM 2Dby dickinsonreNote:  The SWMM51DComponents in InfoSWMM2D
InfoSWMM2D uses standard SWMM5components to connect the 1D Nodes to the 2D Mesh.  A bottom outlet orifice at the maximum depth of the node drains to a SWMM5 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. InfoSWMM2Dautomatically 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 SWMM5 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.

2nd Difference:  Outfall Nodes are crea…

Subject:   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 Fileby dickinsonreSubject:   How to Compare the OutputManagerStatistics in H2OMAPSWMM to the SWMM5OutputTextFile The value of the total inflow in the textoutputfile 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 i…

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 Solutionby dickinsonreNote:Comparison of the H2OMAPSWMMHazenWilliamsForceMainSolution to a HWSolution In this example, we compare the forcemain head loss in four links in H20Map SWMM to the head loss in a steadystateHazenWilliamssolution for the same length pipe, diameter and flow (Figure 1).  The H2OMapSWMM 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 forcemain (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 a…
