Andrea,

The ArcHydro Tools extension for ArcGIS 9.3.1 was developed and maintained by Esri Water Resources team and is still available for download from Esri's secure ftp site. It uses AGREE methods to characterize drainage.

See this ArcHydro forum thread for login and download instructions: http://forums.arcgis.com/threads/82087-New-password-for-Arc-Hydro-ftp-site

Make it easy on yourself and use a secure transfer program, I prefer FileZilla but there are others.

Once installed, there are tutorials and exercise data and you can ask for help in either the ArcHydro or Hydro forums.

p.s. If you really wan't to dig into the raster analysis methods, have a read of D. Nagel, J. Buffington & C. Luce on IDDEA (US Forest Serivce) vs AGREE (Esri - Hellweger/Maidment) methods in this talk -- http://www.fs.fed.us/rm/boise/AWAE/scientists/profiles/Nagel/Nagel_NWGIS2011_DrainageEnforcement_Compressed.pdf
