Can SWMM routing the Channel inside a basin ?

Recommended Posts

By Rational Method we can build hydrologic Basin and compute subbasin flow as well  SWMM  can run the flow through the Storm Drain and watch the routing in channels .

1) can we route channel inside a Basin?

 

2) can we use Rational Method without define outlet point(point)  ? can we identify the channel ( Arc ) as output of basin ?

I'm not a SWMM expert, but there is no way to handle channel routing inside a basin that I can think of.  When using the interface in WMS, I think you need an outlet point to build your model and export it to the SWMM model.

I think so .we can't create an SWMM model without links and nodes.both of them is necessary.

SWMM  manual say's that: An idealized sub catchment is conceptualized as a rectangular surface that has a uniform slope and a width W that drains to a single outlet channel.Each sub catchment can be further divided into three sub areas: an impervious area with depression (detention) storage, an impervious area without depression storage and a pervious area with depression storage. Only the latter area allows for rainfall losses due to infiltration into the soil.

SWMM claims that visualize the sub-basin as v-shape basin but can't model an idealized sub-basin simply.

I am searching a method to define an idealized sub-basin. I will find it ... I know.
