ESRI has created it’s own social network for user’s of its software called GeoNet. Back in March, ESRI created a webinar titled “Community Maps for Hydrology” and can be viewed here. The entire video is 53 minutes. Viewers might want to fast forward to about the 22 minute mark where the speaker starts to talk about and demonstrate the watershed delineation and downstream trace tools.  If you have points on a stream in a watershed, it is a fairly straightforward affair to delineate a watershed in either ArcMap or ArcGIS Online.  The appeal to doing this workflow in ArcMap is that if the delineated watershed is in a geodatabase, it is easy to get an area straight from the attribute table.   The video also discusses maps that provide real-time stream gage data and how it is possible to get a hydrograph plotted just below the map.

ESRI has also updated Maps for Office to version 3.  The interface is a bit more modern. As for new functionality, I think one of the biggest additions is that users can have more than one map displayed for a given tab.  ESRI’s blog post on the update is available here.
