Arc Hydro Tools version 1.1 beta 2 are included on this CD.  The Arc Hydro Tools are a set of utilities developed on top of the Arc Hydro data model.  The tools have two main purposes.  The first purpose is to assign key attributes in the Arc Hydro data model.  These attributes form the basis for further analyses.  They include the key identifiers (such as HydroID, DrainID, NextDownID, etc.) and the measure attributes (such as LengthDown).  The second purpose for the tools is to provide some core functionality often used in water resources applications.  This includes DEM-based watershed delineation, network generation, and attribute-based tracing.  The zip file below contains both the setup file to install Arc Hydro Tools and documentation describing the functionality for each tool.
