InfoSWMM and H2OMAP SWMM Import and Export of HEC-RAS Geometry Data

by dickinsonre
InfoSWMM v11 and H2OMAP SWMM v10 have new import and export features for HEC-RAS interaction.   The echange commands are in the exchange menu (Table 1) and you can import HEC-RAS geometry files (Figure 1), edit imported Transect Data (Figure 2 and 3) and export thedata back to a HEC-RAS geometry file (Figure 4 and 5 and Table 2).

H2OMAP Sewer and InfoSewer Water Quality Options

Subject:   H2OMAP Sewer and InfoSewer Water Quality Options

H2OMAP Sewer and InfoSewer Water Quality Options

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

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.

[Flood_Node]
10309D      848
80408        131

2nd Difference:  Outfall Nodes are created for the 2D Mesh Element connected to the 1D Node, the outfalls are Fixed Outfalls and the fixed head is the Node Rim Elevation of the 1D node listed in the Flooded Node Section

[OUTFALLS]
10208  89.900000     FREE  NO
10208A           89.900000     FIXED            94.400000     YES
10208B           89.900000     FREE  NO
10208C           89.900000     FREE  NO
10208D           89.900000     FREE  NO
10208E           89.900000     FREE  NO
10309D_OUTFALL           101.600000            FIXED           111.000000            NO
80408_OUTFALL             120.000000            FIXED           133.400000            NO

3rd  Difference:  Bottom Outlet Orifices are created to connect the 1D node to the 2D Mesh Element Outfall with the Flood Discharge Coefficient entered by the user and a crest height equal to the maximum depth of the node

[ORIFICES]
OR1@82309B-15009B  82309B      15009B      BOTTOM    0.000000   0.850000   NO

10309D_ORIFICE       10309D      10309D_OUTFALL       BOTTOM    9.400000   0.030000   NO

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

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 File

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

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.
