12. Automated Control Systems 50386 DCU at an upstream water level site monitors water level: Pressure Transducer Float switch When alarm water levels are detected, transmit secure alarm reports. 50386 DCU at a downstream site receives alarm reports transmitted by the upstream water level site and triggers the control: Flashing roadway signs Siren

13. Flashing Roadway Sign Upstream water level triggers flashing roadway signs when water flows over roadway.

14. Automated Siren Warning Upstream high water level triggers a downstream siren.

15. Base Station Software The NovaStar base station software collects data from multiple watersheds, displays text and graphical reports, and checks for alarms. Web page data access of current and historical text and graphical data. Alarm warnings with digitized voice dialers, email, and pager notification. Siren and low water crossing light status viewing and control from web page. Automated data export in text, SHEF, and XML.

17. Multi-user web page access to base station database No client access software required User preferences kept on client workstations Client side user interface keeps band width low SQL database design allow open access to database SQL replication used to synchronize master database with backup database servers Linux operation system Reliable and robust operating system Operating system not subject to Microsoft virus attacks Can be installed on virtual servers NovaStar 5 Software Advantages

18. Web page user interface to list and edit

19. Locally hosted database Data is kept onsite to insure ownership Local access to data continues when external internet access goes down Local database backups Multiple database servers with synchronized database A change in the master database is immediately copied to backup databases through SQL replication Scheduled database backups Intranet database backup to local backup servers Internet database backup to HydroLynx NovaStar 5 Database Advantages

25. Assign Ratings

26. Alarm triggers Upper limit Lower limit Rise over time (rainfall) Fall over time Distinct level No report Too many reports Data collection down Network synchronization down.

27. NovaStar 5 Alarm Checking

28. Data edit

29. Run forecast model manually or schedule automatic forecasting

30. Create plot show observed and forecast data

31. Database reads and writes can be done from any database server Web page browsers connect to one of the NovaStar 5 database servers to read and write data User login determines role for database access Users have unique login names or share a global name Login names are assigned to one or more user roles A guest role prevents write access to the database User groups limit access to the database Stations, sensors, maps, plots, and reports can be limited to a user group or user name NovaStar 5 User Access Advantages

32. Client side user interface Web page browser user interface requires no training User preferences are kept on user workstation Browser shortcuts provide quick access to pages NovaScore feature of database flags significant data Alarm triggers set data report score values Score values highlight data on maps and in data tables Links on data provide drill down functionality Edit data reports Check point parameters Recalibrate data NovaStar 5 User Interface Advantages

33. Highlight data background to show increased hydrologic threat
