iUtah pinpoints precipitation

NSF Award:

iUTAH-innovative Urban Transitions and Aridregion Hydro-sustainability  (Utah State University)

Congressional Districts:
Research Areas:

As the third driest state in the nation, Utah requires efficient water use strategies. Through iUtah, an Experimental Program to Stimulate Competitive Research (EPSCoR) project, researchers have created a sensor network to track every drop of water that falls in the state. The Gradients Along Mountain to Urban Transitions (GAMUT) network monitors falling precipitation, mostly rain and snow, and follows it as it travels from mountainous to urban environments.

iUTAH seeks to better understand the factors that impact interactions between urban settings, environmental change, water infrastructure, water use and decision-making. By collecting, storing and analyzing important water-related data, GAMUT will assist Utah's water resource users and managers. The project will improve water use by developing:

  • a baseline scenario about the current state of the water supply,
  • a scientific-based approach to the decision-making process for current and future water use, and
  • a foundation for long-term decisions on water use for a rapidly growing population, taking into account foreseeable issues related to global climate change.


  • climate sensor station in the iutah network measures many environmental variables
