RouteChannel
| OTTHYMO object | VOSWMM object |
|---|---|
RouteChannel  |
Junction with a downstream Conduit. The Junction is added at the upstream of the Conduit to facilitate the connection in VOSWMM.  |
The parameters of VOSWMM Conduit are assigned as:
- NHYD = RouteChannel NHYD
- Name = RouteChannel Name
- Shape = Irregular
- Shape Curve = RouteChannel Cross Section Coordinates table. Conduit Full Depth and Geom1 will be updated automatically in VOSWMM.
- Length = CHLGHT
- Roughness = length_average(Manning’s n table), where length_average(Manning’s n table) is the length weighted Manning’s n based on the Manning’s n table of the RouteChannel.
- Inlet Offset = CHSLOPE/100 x CHLGTH
- Flap Gate = Yes
- Other parameters keep as default as in VOSWMM.
The parameters of VOSWMM Junction is kept as default as in VOSWMM, but its Treatment field may be updated with Pollutant. Please refer to the section of Pollutant Removal for details.
CompoundChannel
| OTTHYMO object | VOSWMM object |
|---|---|
CompoundChannel  |
Junction with a downstream Conduit. The Junction is added at the upstream of the Conduit to facilitate the connection in VOSWMM. |
The parameters of VOSWMM Conduit are assigned as:
- NHYD = CompoundChannel NHYD
- Name = CompoundChannel Name
- Shape = Irregular
- Shape Curve = RouteChannel Cross Section Coordinates table. Conduit Full Depth and Geom1 will be updated automatically in VOSWMM.
- Length = max(CHLGHT + FPLGTH)
- Roughness = length_average(Manning’s n table), where length_average(Manning’s n table) is the length weighted Manning’s n based on the Manning’s n table of the CompoundChannel.
- Inlet Offset = (average(CHSLOPE,FPSLOPE))/100 x Length
- Flap Gate = Yes
- Other parameters keep as default as in VOSWMM.
The parameters of VOSWMM Junction is kept as default as in VOSWMM, but its Treatment field may be updated with Pollutant. Please refer to the section of Pollutant Removal for details.
