Limiting Sublimation Losses of Critical Water Supply Snowpack

We recently finished our final project documentation which you can access from the links below.

The initial project idea came from Dr. Rand Decker. The goal of the project was to limit sublimation losses of snow so that more snow would be retained on the ground, and higher volumes of snowmelt would go into surface waters and water storage facilities. Sublimation and snow were the focus of this project because arid climates, including Arizona, are the most dependent on snowpack. Up to 70-80% of water in the western United States originates as snowpack. In Arizona, roughly half of the water comes from snowpack; additionally sublimation rates can account for over 50% of snow loss in the state. Based on this information, if sublimation losses could be limited, substantial gains in water may be made for the state, where water is an over-allocated resource.

Our client wanted some unique treatment ideas to be tested for the first time. In addition, he wanted the treatments to be tested in several different landscapes that would be typical of the areas this treatment would most likely be applied. Any of the treatments had to be applicable on a landscape scale as well as cost effective. Finally, the client wanted to know the relationship between snowpack and forest health, as well as the importance of snowpack in the western United States and specifically, Arizona.
