Optimization Models for a Real-World Snow Plow Routing Problem

In cold weather cities, snowstorms can have a significant disruptive effect on both mobility and safety, and consequently the faster that streets can be cleared the better. Yet in most cities, plans for snowplowing are developed using simple allocation schemes that while easy to implement can also be quite inefficient. In this paper we consider the problem of optimizing the routes of a fleet of...

Snow Accumulation and Distribution in an Alpine Watershed

Distribution of snow water equivalence (SWE) was measured in the Emerald Lake watershed located in Sequoia National Park, California, by taking hundreds of depth measurements and density profiles at six locations during the 1986, 1987 and 1988 water years. A stratified sampling scheme was evaluated by identifying and mapping zones of similar snow properties on the basis of topographic parameter...

Stereological Characterization of Dry Alpine Snow for Microwave Remote Sensing

A persistent problem in investigations of electromagnetic properties ofsnow, from reflectance at visible wavelengths to emission and backscattering in the microwave, has been the proper characterization of the snow’s physical properties. We suggest that the granular and laminar structure of snow can be measured in its aggregated state by stereology performed on sections prepared from snow speci...
