Rio Grande Basin Initiative

2002-03 Deliverables

Task 8 Research
Principal Investigator(s): Raghavan Srinivasan

  1. Volumetric water requirements by canal in specific irrigation districts of the Lower Rio Grande Valley under current management and crop conditions using historical weather conditions for the period 1960-2001.
  2. Volumetric water requirements by canal and district associated with selected water conservation measures as specified by district managers.
  3. Volumetric water requirements by canal and district as affected by transmission efficiency, in-field conservation, alternative cropping systems and district management.

  1. Buy and setup a server with arcims software to hold regional spatial databases.
  2. The Spatial Sciences Laboratory at Texas A&M University ( will develop an interactive, Web-based, GIS for the fourteen counties in Texas along the Mexico border for one year:
    1. Brewster
    2. Cameron
    3. El Paso
    4. Hidalgo
    5. Hudspeth
    6. Jeff Davis
    7. Kinney
    8. Maverick
    9. Presidio
    10. Starr
    11. Terrell
    12. Val Verde
    13. Webb
    14. Zapata
  3. Web-enabled GIS provides interactive query capabilities such as:
    1. Searching for specific site locations
    2. Displaying, viewing, and analyzing multiple data sets
    3. Conducting queries for specialized analysis
    4. Production of high quality cartographic information
  4. The information included in the Web-based GIS will be wide-ranging. The following are examples of types of information to be incorporated into the GIS. As new information is developed, it can quickly and easily be incorporated into the GIS.
    1. Environmental
      1. Hydrologic unit boundaries (USGS)
      2. EPA regions (USGS)
      3. National Water Quality Assessment (NAWQA) study unit boundaries (USGS)
      4. Reach File Version 1 (RF1) provides stream network for major rivers and supports development of stream routing for modeling purposes (1:500k) (USEPA)
      5. Reach File Version 3 (RF3) Alpha alpha version of Reach File 3; provides a detailed stream network and supports development of stream routing for modeling purposes (1:100k) (USEPA)
      6. Water quality monitoring stations and data summaries (USEPA)
      7. Bacteria monitoring stations and data summaries (USEPA)Water quality stations and observation data (USEPA)
      8. National Sediment Inventory (NSI) stations and database (USEPA)
      9. Listing of fish and wildlife advisories state reporting of locations with advisories for fishing (USEPA)
      10. Industrial facilities discharge (IFD) sites (USEPA)
      11. Toxic release inventory (TRI) sites and pollutant release data (USEPA)
