Summary/Goals: This project is funded under a Center-Directed Initiatives grant through the Water Sustainability Program and reports on a fiscal year basis.
The goal of this project is to develop a near real-time monitoring system that traces terrestrial water storage (TWS) dynamics in the Colorado River (and sub-basins, such as the Upper Colorado) based on the procedure outlined in Troch et al. (2007)1 . In addition, in-situ data on ground water (USGS), snow water equivalent (SNOTEL), and reservoir operations (USBR) will be collected to supplement the above mentioned methods. Data and analysis results will be stored in the SAHRA Geo-database and include NCEP-NARR and GRACE data.

Plans for the upcoming year:
The different tasks and associated deliverables of the project are: (i) develop web-services to pull in data in near real-time from existing data sources, and store them in appropriate formats for further processing (July 1 to October 30, 2007); (ii) converting data into information using the procedure of Troch et al. (2007) and (advanced) interpolation techniques for in-situ data to produce bi-weekly TWS estimates (September 1 to December 31, 2007); (iii) dissemination of the results in real-time through a SAHRA/HWR website (January 1 to February 15, 2008); (iv) maintaining web site and web services and producing technical manual/scientific paper (February 1 to June 30, 2008).
