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
Table 1. Exchange commands in InfoSWMM and/or H2OMAP SWMM
Figure 1. Import HEC-RAS command imports Geometry Files which will have the extension go1, go2 etc.
Figure 2. The imported Transects can be viewed and edited in the Operations Tab of the InfoSWMM Browser.
Figure 3. The imported Transects can be used as a SWMM 5 Irregular Channel Transect.
Figure 4. Export HEC-RAS command exports a geometry file containing the active Transects in InfoSWMM.
Figure 5. Export HEC-RAS allows you to choose a directory and a name for the exported geometry file.

Note: The SWMM 5 1D Component
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
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.
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
10208 89.900000 FREE 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

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