Lets see if this makes sense...
I'm fairly new to this program, but have been trying to show where a flow will go if I interrupt it. I've created a stream network based on a real watershed, but I want to block the flow in one of the tributaries to see (well, prove a theory) where it will form a new path.
How can I go about this?
The stream network I made did not have a pour point, I was able to use to fill-flow direction-flow accumulation- [condition to form a stream network] - stream link. This formed a perfect match to the known stream network
I've discovered how to create a sink, but cannot incorporate it into the model to divert the flow (I guess I am not putting it in right)
I thought I created a pour point, but no image resulted when I tried to run it in the model.
Should I use a different methodology to model the network?
Is there a way I can place the sink stipulation into the DEM before beginning the process to get a stream network without it being filled?
or am I going about this all wrong???
