Background Advanced Hydrologic Prediction service

8. Objectives Provide a service GIS model for future flood studies
Protect the economic investments and interests of community
Facilitate Rescue, Recovery, Prevention
Aid in land use policy and recreation

9. Map of the Ventura River
Three Parts

11. Methods and Procedure Three Parts to the Procedure: The Event
The Physical and Social Impact
Rescue and Recovery

12. 1. The Event Identify the site (the creek a.k.a the event)
Need to find data:
- rain gauges
- hydrographs
 3 highest peaks
- Imagery
 air photos
 Landsat data

13. Hydrograph http://nwis. waterdata. usgs. gov/ca/nwis/peak/

14. Hydrograph http://nwis. waterdata. usgs. gov/ca/nwis/peak/

15. 2. Physical and Social Impact
Transportation – roads, railroad, airports
Livelines – gas, water, sewage, electricity
Buildings – schools, residential, business
Land use – agriculture
Communication systems – cell towers, radio stations

16. 2. Phys. And Soc. Continued Economic – jobs, income
Population breakdowns – families, age
Property value
Displaced population

17. 3. Rescue and Recovery
Depends heavily upon physical and social Impacts:
Roads blocked and closed
Flooding of emergency areas
Economic losses and damages
Funds for repair

18. Data sources USGS - rain gauges - DEM MIL - Aerial photos Census Data
Ventura Community
On site Inspection

20. Anticipated Problems Locating affected areas
Finding associated ancillary related to past events
Predicting future floods
Finding accurate census data for the social impacts
Difficulty communicating and distributing information to residents

21. Likely Results
Providing service to search & rescue and the fire department
Restricting land use to low intensity recreation and economic activity
Produce three thematic flood prediction maps
Ultimately…
Saving Ventura
