GIS Support For Water Resource Management in the Tecate, California and Tecate, Baja California Section of the United St

1. GIS Support For Water Resource Management in the Tecate, California and Tecate, Baja California Section of the United States – Mexico Border

2. Overall Project Goal • To Assist Stakeholders in Managing Scarce Water Resources in the Ambos Tecates section of the border region • Goal will be accomplished through the development of a water-focused GIS database and web-based tools

3. U.S. – Mexico Border

4. Urban Pairs in the U.S.-Mexico Border Region

5. Tijuana River Watershed

6. Ambos Tecates in the Tijuana River Watershed

7. Ambos Tecates Project Area Population: Tecate, MX – 78,000 in 2000Tecate, US – >200 (2,000 in larger area) Border Crossings: 2.7 Million in 200257 Million in S.D. – B.C.(only 5% of S.D. – B.C total)

8. Ambos Tecates

9. Ambos Tecates • An inadequate GIS infrastructure for supporting government decision-making is a characteristic shared by most urban pairs along the United States – Mexico border

10. Relation to Recent Existing Projects/Programs • Tijuana River Watershed Binational Vision • Tres Californias • Integrated U.S.-Mexico Geographic Information System for Transboundary Watershed Management • Identification and Mapping of Potential Ground Water Contamination Sources in Urban Tecate, Mexico

11. Tijuana River Watershed Bi-national Vision • Purpose To develop a bi-national vision for the Tijuana River Watershed and devise strategies and options for achieving the vision based on stakeholder participation • Origins • Tijuana River Watershed GIS, 1994-2000 • San Diego-Tijuana International Border Planning Atlas, 2000 • Tijuana River Watershed Atlas, 2005

12. Integrated U.S.– Mexico Geographic Information System for Trans-boundary Watershed Management • Purpose To develop and implement a strategy for a bi-national water resources GIS in the U.S.-Mexico border region • Project is led by Chris Brown, Jean Parcher, and Fabian Lozano • The Ambos Tecates project is one of the pilot projects of this program

13. Tres Californias • Purpose To increase university and stakeholder cooperation, technology transfer, and the enhancement of local and regional planning • Anticipated Results Collection of new data, increased access to existing data, improved ability to create maps, and better tools to analyze spatial and tabular data • Geographic Focus Two southernmost counties of California, Baja California, and Baja California Sur • Targeted Users State and municipal government planners and decision makers • University Partners • San Diego State University • The Autonomous University of Baja California, Ensenada • The Autonomous University of Baja California Sur

14. Identification and Mapping of Potential Ground Water Contamination Sources in Urban Tecate, Mexico • Purposes • To create a GIS data storage and analysis tool for water resources in Tecate, Baja California, Mexico • Inventory Possible groundwater contamination sources • Provide GIS training to employees of the State Commission in Tecate and the Tecate Municipal Planning Department

15. Modeling Flood Risk

16. Flood Risk Evaluation Model HI = Sli + Sti(0.5) + Gi and VI = Lui FRI = HI + VI FRI = Flood Risk Index Hi = Hazzard index Sli = Slope index Sti = Stream index Gi = Geomorphology index Vi = Vulnerability index Lui = Land use index
