The source area for the createstreamnetwork is the area at which you
want a stream channel or overland flow to begin.  Thus if you specify
10000 as your source area you are saying that a stream channel will
initiate at an area of 1 hectare (10000 m^2).  So the determination of
what source area to use should be a decision based on the climate and
conditions for the watershed you are working.
 
One thing to keep in mind, I did this, is once you create your stream
network in createstreamnetwork you can then take the resulting GIS layer
and edit the stream arcs within GIS software to more accurately reflect
your basin's stream network.  Then run your edited stream network
through createstreamnetwork to produce the necessary files for DHSVM use
(stream.map.dat, stream.network.dat).

In order to create stream network, in DHSVM FAQ's refer to DEMON in
order to estimate source area. Can anybody help me in getting and
understanding this?
