Emergency Management through Visualization
Douglas Blatchford, PEPennsylvania State MGIS Program
Advisors: Dr. Miller, Dr. Reed, Dr. Kollat Geography 596A, Summer 2013
Background Colorado River/Gila River Systems Operation and emergency management forecast web
apps in the Phoenix metropolitan area Visual Analytics
Goals and objectives Enhance existing web-based tools through visualization
Proposed methodology Develop mash-up based on Google Map API
Project timeline
Overview
Gila is a major tributary to the Colorado River System Flows through southern Arizona
Dams provide water supply and flood protection for Phoenix metro area
Dams operated by Salt River Project (SRP) and the United States Army Corp of Engineers (USACE)
Operations forecast is key to managing water resources
Background
Colorado River Basin
-Colorado River supplies water to municipalities and irrigators throughout the West-Dams along the river are operated to meet water user demands in Arizona California , Nevada and Mexico
-Accessed from the Colorado River Water Users Association (CRWUA), July 2013 from http://crwua.org/ColoradoRiver/RiverMap.aspx
Gila River Basin -Gila-Salt-Verde River system, New Mexico and Arizona as related to the Colorado River
-Flow along the Gila at Yuma affects major operations of Colorado River and water levels in Lake Mead, behind Hoover Dam
Accessed July 2013 from http://www.lifeinlakehavasu.com/lower-colorado-river-area.html
Facilities Gila-Salt-Verde River system drains through Phoenix metropolitan area. SRP facilities provide water supply and flood control protection. Dams include :
-Gila: -Painted Rock and Coolidge -Salt: -Stewart Mountain, Mormon Flat,
Horse Mesa and Roosevelt -Verde: -Bartlett and Horse shoe
Operations Forecast The Colorado River Basin Forecast Center (CBRFC) issues forecasts online for the Gila-Salt-Verde River system as well as other major rivers in the basin.
Accessed July 2013 from the CBRFC (http://www.cbrfc.noaa.gov/)
Operations Forecast River operators and emergency managers typically access existing and future gage data.

Operations Forecast Gila River watershed from CBRFC website.

Operations Forecast
USACE provides a webpage with links to Gila-Salt-Verde River system and USGS gage sites.
-Provides easier access to existing data-No forecast modeling like CBRFC

Visual analytics is an outgrowth of the fields of: Information visualization Scientific visualization Analytical reasoning Facilitated by interactive visual interfaces
Goal is to process data for analytic discourse Constructive evaluation, correction, and rapid
development of processes and models This ultimately improves our knowledge and
decisions
Visual Analytics
Ward (2009) describes a visual pipeline as: The process of starting with data Generating an image or model via computer Sequence of stages studied in terms of
Algorithms Data Structures Coordinate systems

Develop a “one-stop” source of web-based forecasts for the Gila-Salt-Verde system
Implement web-based prototype and tool using the concepts of visual analytics
Increase SRP and USACE operational efficiency
Goals and Objectives
Develop mash-up to be tested by operators at USACE and SRP Use a Google Map API, with Fusion Tables Includes gage, dam and other hydrographic
informationVisual analysis will be tested by timing
access to information Questionnaire developed for operators,
asking to access gage data from the prototype or from the CBRFC or USACE websites
Proposed Methodology
Geographic extent: Painted Rock Dam on the west to Coolidge on the east
Designed as a prototype specific to SRP/USACE Further work will be necessary to offer more
capabilities Anticipated outcome: will take less time to access
forecast data Existing mash-ups already use National Climatic
Database (NCDB) such as WunderMap (http://www.wunderground.com/wundermap/)
Proposed Mash-up
Existing Products
Taken from Weather Underground (accessed July 2013 from http://www.wunderground.com/wundermap)
August 14 to September 30 – Complete Mash-up
October 1 to October 23 – Complete testing and capstone report
May 12-14, 2014 - Present paper at American Water Resources Association Spring Specialty Conference in GIS and Water Resources, Decision Support in Water Resources, Salt Lake City (permission pending)
Project Timeline
Propose to develop prototype Mash-up based on Google API
The intent is to enhance river operations forecasting along the Gila-Salt-Verde River System
Concepts of visual analytics will be used to develop the prototype
