Arc Hydro Tools 

Work with the elements of ArcMap environments. Create new objects and manage existing ones, adjust the parameters of specific items to optimize the performance, integration, and functioning of entire setups. Display all compatible objects and view interaction options.

The Arc Hydro Toolset is a suite of tools which facilitate the creation, manipulation, and display of Arc Hydro features and objects within the ArcMap environment. The tools provide raster, vector, and time series functionality, and many of them populate the attributes of Arc Hydro features.
