Terrain Processing Steps.

Question

Hi all,
i am confuse in these steps (1-Dem Reconditioning, 2-Fill sinks, 3-flow direction).  Kindly guide me about the sequence is it correct sequence or not? if it is incorrect then which step should i perform first?

@MarkBoucher  and everyone, wanted your opinion on something:

I am working on a hydrological modeling project in a relatively mixed agricultural area using a 10m resolution DEM captured via Radar. The study area is topographically diverse, covering both flat agricultural plains and the more rugged, incised valleys.

I am using the ArcHydro DEM Reconditioning tool to burn in a vector watercourse layer. I’m trying to find the right balance for the AGREE algorithm parameters to ensure flow consistency without over-distorting the terrain.

I am currently considering these parameters:

Number of cells for stream buffer: 3

Smooth drop: 5

Sharp drop: 30

Any suggestions on how to set these parameters would be really appreciated
