Riverside has also worked with the CWCB to develop a DSS for the South Platte River in Colorado. An important component of the DSS is to perform irrigated lands delineation utilizing the Landsat platform and to provide information for decision making regarding water resources and agricultural crop production in the South Platte.

Riverside has also worked with the CWCB to develop a DSS for the South Platte River in Colorado. An important component of the DSS is to perform irrigated lands delineation utilizing the Landsat platform and to provide information for decision making regarding water resources and agricultural crop production in the South Platte. The objectives of the South Platte DSS are as follows:

  • Develop accurate, user-oriented databases helpful in the administration and allocation of the waters of the South Platte River and its tributaries,
  • Provide data and models to evaluate alternative water-administration strategies,
  • Accurately represent current and potential federal and state administrative and operational policies and laws, and
  • Promote information sharing among government agencies and water users.

Riverside has provided the spatial information systems component of the South Platte DSS, beginning with a comprehensive GIS database and spatial-analysis tools. Thirty-meter (m) multi-temporal Landsat satellite images are used to map an estimated 1.5 million acres of irrigated lands in the basin and to estimate the consumptive water use for each irrigation diversion and for irrigation wells in the basin (figs. 1 and 2). The mapping was completed in consultation with State of Colorado water resource managers, water conservancy districts, and hundreds of irrigation ditch companies and water users.
