The BAGIS-H tool provides the following four major functions. We anticipate that a beta version of BAGIS-H will be available on the Downloads page in late October 2011.

1. HRU delineation: This function allows the user to define a set of HRU zones using a customizable set of rules and templates. The resulting layer represents a set of hydrologically homogenous layers.
2. HRU post-processing: Post-processing functions allow a set of HRU zones to be refined by removing zones that are too small, merging zones based on similarity of the zones, subsetting zones to form a new output layer, or inntegrating HRU zones from multiple HRU layers
3. Process logging: This function records all actions that are taken when defining or refining a set of HRU zones. The log documents a complex process and eases the iterative processes required to fine-tune algorithms.
4. Data management module: This function maintains a well-organized datastore in ESRI file geodatabase format and allows close examination of data layers in ArcMap. Outside layers can be added to the analysis using this function.
