GPR offers a simple and rapid means of providing information for mapping snow thickness. Snow thickness data are of great importance in hydrological studies where snow melt can lead to floodIng. In many countries with hydroelectric power generation, water storage in the snow pack represents a key input to reservoir level control planning. At first glance, the snow thickness problem would appear trivial, and indeed measurement of snow thickness can be straight forward. Unfortunately, the economic applications of snow thickness data require equivalent water content (not snow thickness)!! To effectively use snow thickness information, it is necessary to develop systematic procedures for transforming GPR snow thickness observations to water content. In this paper we describe the steps required to achieve the water content objective. An illustration of this approach and associated difficulties is provided using multi fold GPR data acquired on an area of multi-year snow in Norway.
