Lesson 1 Introduction

• CHPS configuration utilizes XML as a framework for data.

• Remember, XML does not perform an action; it provides structure and transportation for information.

• The CHPS Configuration Focal Point identifies opportunities to optimize CHPS by:
  • decreasing use of storage space
  • establishing new data sources
  • setting up a model from a university or another agency.

Lesson 2 Data Handling

• When adding new data sources to CHPS, consider these items:
  • What is the data format?
  • Is the data type already being imported?
  • How precise should the data be (i.e., how many significant digits should be used)?
  • How long do you want the data in the system? Determine the expiry time.

• To add a segment, follow these steps:
  1. Add a new site to the Locations.xml and LocationSets.xml files
  2. Create a subdirectory for the new segment
  3. Create a ModuleConfigFiles subdirectory and contents for the new segment
  4. Create the cold states files
  5. Create the workflow files
  6. Register the ModuleConfig and Workflow files
  7. Create a segment tree and entries in the IFD Forecast tab
  8. Update the ModuleInstanceSets
  9. Set up the forecast plot display
  10. Test the segment in a Stand Alone instance
  11. Add a rating curve and data
  12. Complete the spin-up runs
  13. Validate new configuration
  14. Upload the new configuration

• To optimize runtime for ensemble forecasts, you can remove unwanted time series from the ensemble runs to speed up processing time or by splitting up the workflows over several FSSs.

• Setting a time series as “temporary” decreases synch time, causes less database fragmentation, and saves space in the datastore.

Lesson 3 Products

• In order to configure the Pi-Service, define the type of data you are sending to the office, the data locations (i.e.: site ID’s, handbook 5 ID’s), and the directory to which the data is being pushed.

• The steps to configure the Event Action feature are as follows:
  1. Choose an event code to use as a trigger.
  2. Create an action configuration file.
  3. Upload the XML file from Step 2 to the Admin Interface, choosing a suitable action ID.
  4. Create an Event-Action Mapping to link the event code and the action ID.
  5. Schedule the appropriate task with the same tag as configured in the XML file.

• There are two options for inundation mapping: 1) Flood Mapping Module, which produces 2D maps outlining inundated areas, and 2) Using ArcGIS.

• PC Raster, a type of environmental modeling software, utilizes the Transformation and General Adapter modules to create simulation models such as runoff models.

• The Report Module puts data into a desired format, generates the reports from FEWS, and displays the reports in HTML format. The report templates organize the information into text, charts, and tables.
