We’ve gone live with the new design for the Western Waters Digital Library! The redesign, done by Leah Martin of the University of Utah’s J. Willard Marriott Library’s Discovery and Web Development group is designed to look great on browsers with varying screen sizes, including tablets and smartphones. We also have a new exhibits page to highlight, with contributions from Southern Methodist University’s DeGolyer Library, University of Washington Libraries, and WWDL maps from the Digital Scholarship Lab at the J. Willard Marriott Library. Thanks to everyone involved in the redesign!

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 programNatural 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.”
