  1. SCERP Efforts Employing GIS in Water Resources Research on the US-Mexico Border Dr. Christopher Brown New Mexico State University Department of Geography 2006 SCERP/USGS GIS Summit UTEP – 10 April 2006

  2. Acknowledgements • Southwest Consortium for Environmental Research and Policy (SCERP) for funding • Richard Wright and Fabian Lozano for work on previous iteration of work • Jean Parcher and Jim Stefanov for USGS support and collaboration • Alfredo Granados, Nori Koehler, and Janet Greenlee for assisting with GIS work in the Paso del Norte region

  3. SCERP’s History of GIS Work • Many smaller scale projects have been funded in last 15 years (www.scerp.org) • SCERP is a natural vehicle to advance broader comprehensive effort • Border wide focus, many partners, much talent • Long term interest and commitment to GIS work • Connection with USGS allows multiple scaled effort with broad scope

  4. Selected highlights of SCERP GIS work • SDSU lead many efforts in 1990s to advance binational GIS work • Transboundary Watershed Research Program advanced by ASU and SDSU researchers • University of Utah use of GIS in range of areas • Recent water resources vulnerability research • Paired basins work of SDSU and NMSU researchers • Examined Tijuana and Rio Grande Basins • Preliminary outcomes also identified crucial data fusion issues

  5. Early SDSU Tijuana Basin Work • Workshops in 1990s examined basic issues involved in integrated binational GIS work • Pioneering development of seamless binational watershed GIS database • Award winning mapping work (NGS award) • Support for wide range of applied GIS work • Binational soils mapping (Askov 1997) • Examination of land use and water quality work (Brown, Placchi and Gersberg 1998) • Instrumental in Tijuana River Watershed Visioning Project (Ganster and Comer 2004-2006)

  6. Transboundary WatershedResearch Program • Joint project of SDSU and ASU researchers • Goal was to explore GIS and water resource modeling in the San Pedro and Tijuana Basins • Specifically, Better Assessment Science Integrating point and Nonpoint Sources (BASINS) software was employed in two binational watersheds • Also explored USEPA Index of Watershed Indicators (IWI) approach to develop specific indicators in Tijuana Basin

  7. University of Utah’s Research • Exploration of how best to communicate results of GIS to user groups (Hepner 1997) • Use of GIS to model of contaminant pathways and human exposure in the Nogales Region (Finco, Hepner, and Miller 1997) • Use of GIS to examine non-point source pollution in Imperial Valley (Finco and Hepner 1998)

  8. Paired Basins Vulnerability Work • SDSU and NMSU funded by SCERP to pursue paired basins work in the Tijuana and Rio Grande Basins • Involved Binational Experts Panel held in Las Cruces, NM in 2003 , with goals of: • identifying sources of vulnerability, • identifying geo-spatial data needed to research these sources • development of geo-spatial products to portray regional variability of vulnerability

  9. NMSU/UACJ Watershed Vulnerability project • Hydroregionalization of the Paso del Norte study area delineated study area • Mapping of specific indicators of interest, based on Experts Panel ideas • Development of a GIS data archive being served on the Web – more to come later • Related identification of gaps in data coverage and data fusion challenges

  10. Specific indicators developed • Evapotranspiration is developed as a dryness measure after Hurd et al 1999. • Standardized Precipitation Indicator developed as a measure of drought and water stress • Exploration of surface water quality issues • Vulnerability of groundwater resources more difficult due to cross-border data differences

  11. Insights gained from review • SCERP researchers have been successful at integrated, collaborative GIS-based research • Recent work has identified key data fusion issues, of much importance to goals of Summit • Importance of cross-border University collaboration • Personal experiences with COLEF, UACJ, and ITESM are especially illustrative • Facilitates two way exchange of data and collaborative GIS analysis • Recent connection with USGS offers much promise for enhanced capability

  12. USGS Binational GIS Initiative The project proposes to encompass the entire U.S.-Mexico border region as indicated by the DOI U.S.-Mexico Border Field Coordinating Committee’s (FCC) Water Resources Issue Team U.S.-Mexico border region as delineated by the FCC using watersheds and protected lands (Woodward and Durall 1996).
