- 15. Hydroperiod Dialog Hydroperiod Dialog Intro: The tools have the following functionality: Generate Rasters Classify Depths Calculate Volume Cell Statistics Zone Statistics Each tool has a limited number of parameters the user can set through this dialog. Advanced users can set further parameters using Model Builder.
- 16. View Ponded Depths with Tracking Analyst After running the “Classify Depths” tool, you can view the depths over time using the ESRI’s Tracking Analyst Extension. Turn on the Tracking Analyst Extension (Tools/Extensions menu) Turn on the Tracking Analyst Toolbar (View/Toolbars menu) Click the Add data button and select the PondedDepth feature class from your geodatabse (source files folder) Set the appropriate parameters and view the animation.
- 17. DHI TimeSeries Tool The DHI TimeSeries tool enables users to import timeseries data from a variety of different data sources including the following: -DBHydro -ArcHydro -Geodatabase -Excel -and many others… After importing the timeseries data, users can view the data over time with the aid of graphs and tables.

- For the South Florida Water Management District, it’s an ongoing data-gathering quest to best manage and improve water quality, flood control, natural systems and water supply . Like many other water agencies, the District relies on dozens of tools and technologies from monitoring stations to GIS and hydraulic/hydrologic modeling solutions to support the numerous projects ongoing at any given time. For AHED we started with four key projects at the District to identify their common needs and enhance Arc Hydro to meet them.
- NOTES: Allows hydroperiod conditions to be evaluated over time Produces hydroperiod time series graphs Supports evaluation of vegetation data relative to hydroperiod Supports simple statistical analysis of sample observations Supports extrapolation of sample data to similar units Supports the comparison of pre- and post-restoration conditions
