Implementing a Web-based Streamflow Statistics Tool for New Mexico (StreamStats)

Science Center Objects

Estimates of streamflow are needed for a wide variety of applications, including water-resources planning and management, flood-plain mapping, and instream flow determinations. Surface water is the primary source of water for irrigators along major stream corridors in New Mexico and is increasingly being utilized by large municipalities. While streamflow statistics for gaged sites are readily available from existing sources, streamflow statistics are needed for ungaged sites where no observed flow data are available. Quantification of streamflow at ungaged locations will provide information that State and local water planners and managers need to insure a secure water future for New Mexico.

Approach

  • Compile a streamflow statistics database
  • Develop digital map-base layers
  • Construct the web-based Geographic Information Systems (GIS) hydrologic framework

Objectives

Provide an interactive web-based tool for determining streamflow statistics (low-flow and peakl-flow frequency) for any stream location within New Mexico for which applicable streamflow regression equations have been published.
