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.

Orifice and Weir flow calculations

Note: Orifice and Weir Flow Computations The orifice flow calculation proceeds as follows: 1. Initially and whenever the setting (i.e., the fraction opened) changes, flow coefficients for both orifice and weir behavior are computed as follows: a. For side orifices: Define Hcrit = h/2 where h is the opening height. b. For bottom orifices: i. For a circular orifice, compute area over length (i.e., circumference) as AL = h /4. ii. For a rectangular orifice compute AL = h*w/(2*(h+w)) where w is the opening width. iii. Compute Hcrit = Cd*AL/0.414 where Cd is the orifice discharge coefficient. At step 1b, the critical head for the bottom orifice, where orifice flow turns into weir flow, is found by equating the result of the orifice equation to that of the weir equation Cd*Area*sqrt(2g)*sqrt(Hcrit) = Cw*Length*sqrt(Hcrit)*Hcrit or Hcrit = (Cd * Area) / (Cw/sqrt(2g) * Length) The value of Cw/sqrt(2g) for a sharp crested weir is 0.414.

EMC Washoff in SWMM5

Image
There are four steps to using EMC concentrations in your network: 1. Define your pollutant by adding a pollutant using the Data=>Quality=>Pollutant command : 2. Define the Land Use by using the Data=>Land Uses command or the Land Use Editor: 3. Define Buildup to be None by clicking on the None Tab: 4. Define the EMC Washoff concentration by clicking on the Washoff Tab: This is where you would add a GW concentration More: http://www.swmm2000.com/
