We are not planning to update the basic step by step tutorial. I started doing just that and with more than 250 tools and many options on how to implement your workflows, it quickly became a nightmare to develop and maintain. So now our objectives are to try to document each tool in the Python toolbox itself and to develop some workflow oriented documentation, similar to what we have done for stormwater. We are planning to revisit the main terrain preprocessing workflows and are finalizing an updated stormwater and a new flood oriented document.
If there are any area/workflows that you would like to see documented beside those?
As for the Arc Hydro training, you can contact Dean Djokic (ddjokic@esri.com). He schedules and teaches them, and will be conducting 2 workshops at the Water Conference next year (on stormwater and on flood).
