Hi,
I am trying to figure out what to input for Buffer Distance, Smooth and Sharp Drop/Raise Distance for Dem Reconditioning. I have read a lot on the internet but none really make sense to me.
I am working on Brevard County in Florida which has a rather flat topography.
I am going to delineate watersheds on the county afterwards.

Thank you in advance.

You can reduce the stream buffer to 2 and it will still work. This helps in some tight places. Setting it to 1 does not aways work for me. This is basically the width of the "slot" created during the "burn".

This old forum post has some explanation of the other values. http://forums.esri.com/Thread.asp?c=121&f=1271&t=183236.

I found this related document and it has some info related to burning streams parameters.  See page 14.
