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).

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.
