As initiated in 2002- <br />2004, these new technologies will be further supported by two-way satellite telemetry systems that <br />allow real-time access to suspended-sediment and stream flow data, as well as remote control of <br />automated monitoring systems. Over the past decade, several numerical models have been developed <br />by cooperating scientists to predict the fate of operational releases from Glen Canyon Dam, as well as <br />their influence on downstream resources, such as fine-sediment. Ongoing collection of high- <br />resolution data related to the mass flux of fine sediment, water and other parameters such as <br /> <br />GCMRC FY2006 Annual Work Plan (Draft February 15,2005) <br />
