Mapping drainage ditches in DEM

I've been looking into ways of automated mapping of drainage ditches from a DEM (The straight line features in the attachment).

I've been getting some decent results using the Hydrology tools in the Spatial Analyst extension.

What i was hoping for some help with is if someone knows any other way to do this using the DEM?

Another thing i would like to try is to somehow automatically calculate the widths and/or depths of the drainage ditches.

Any ideas? I've been looking into creating cross sections but was wondering if there was another way that I'm not aware of?

Thanks for any help.
