Today we are featuring an item from Utah State University’s Digital Repository by David G Tarboton, “Measurements and Modeling of Snow Energy Balance and Sublimation from Snow”
From the description, “Snow melt runoff is an important factor in runoff generation for most Utah rivers and a large contributor to Utah’s water supply and periodically flooding. The melting of snow is driven by fluxes of energy into the snow during warm periods. These consist of radiant energy from the sun and atmosphere, sensible and latent heat transfers due to turbulent energy exchanges at the snow surface and a relatively small ground flux from below. The turbulent energy exchanges are also responsible for sublimation from the snow surface, particularly in arid environments, and result in a loss of snow water equivalent available for melt. The cooling of the snowpack resulting for sublimation also delays the formation of melt runoff. This paper describes measurements and mathematical modeling done to quantify the sublimation from snow.”

Today’s featured item is an article from Utah State University’s Digital Commons
Kirsten Gallo and Wayne A. Wurtsbaugh. “Teaching aquatic ecology within ecosystem and management contexts: The Lake Powell cooperative education program” Natural Resources and Environmental Issues 7.1 (1998).
Available at: http://works.bepress.com/wayne_wurtsbaugh/4
This article describes a course that demonstrates to students how to work with a resource agency. From the abstract, “Resource managers are increasingly asked to work at the ecosystem level of organization and to use team approaches to address management problems. Here we describe a senior/graduate level course that helps students to understand the complexity of an ecosystem, and to begin working with a resource agency. We have collaborated with the Glen Canyon National Recreation Area (National Park Service) to find research problems that will help them manage the Lake Powell ecosystem. The Park Service receives useful research from the program, and they have partially underwritten the considerable cost of teaching the course. Projects undertaken have included studying the significance of the pelagic food web for endangered fishes, and the importance of production processes in the extensive side canyons of the reservoir.”
Today we are featuring the photo “Gerber Watershed – Klamath Project, Oregon-California” which comes to the Western Waters Digital Library from the Klamath Waters Digital Library. The photo’s description goes into more detail, “CN-12-200-37A Gerber Watershed – Klamath Project, Oregon-California. Looking easterly at Gerber Reservoir from top of Gerber Dam. Note that the boat dock located at the far end of the water area in the center of the picture is completely out of the water. Water surface elevation was 4809.62 feet above sea level (USBR Datum). Reservoir content amounted to 16,450 acre-feet; November 19, 1968; Bureau of Reclamation photo by T.J. Rosten”

Today we are featuring the item “Men, medicine & water: the building of the Los Angeles aqueduct, 1908-1913: a physician’s recollections.”
From the description, “Book consists of the journal entries of a Dr. Raymond G. Taylor, a physician who practiced along the Los Angeles Aqueduct during the aqueduct’s construction. He relates personal experiences along the aqueduct and encounters with Owens Valley residents and Los Angeles citizens. Book also contains a section with photographs that trace Dr. Taylor’s journey up the aqueduct.”
This item comes to the Western Waters Digital Library from Claremont Colleges Digital Library.

This week we are featuring “Feasibility of Accelerating Construction of the Central Utah Project,” a report issued in 1978 which discusses the multiple unit project developing water for irrigation and many other uses.
From the report’s abstract: “Objective: In April, 1977 the President’s statement on water projects recommended that a number of federal water development projects, including the Bonneville unit of the Central Utah Project, not be completed. The ensuing efforts of project supporters brought about a review of the projected costs, benefits, and other political, social and environmental factors and consequently, the current issue is not whether or not the project should be constructed. Rather, the objective of this report is to examine the following question: Given the fact that at least the 5 units of the CUP which have already been authorized will eventually be constructed, what is the most desirable rate of construction funding?”
This report comes to the Western Waters Digital Library from Utah State University’s Digital Commons.
