how to get this path: d8 --> d4 --> flow accumulation --> rivers?

Discussion created by taiseer on Mar 9, 2012
Hi,

My target is to have stream network without diagonal connections.
I have the DEM, from which I can generate the d8 flow direction. From the d8 flow direction, I can extract d4 flow direction.
Now it is for not possible to generate the flow accumulation from the d4 flow direction, the available tool in ArcGIS is not working for the d4.

Does anyone have idea(s)?

Thanks
Taiseer
