Estimating Snow Water Equivalent In The Swedish Mountains Based On The Frequency And Amplitude Of The Local Topography
Abstract
Estimating the snow water equivalent (SWE) of the seasonal snowpack is key information for the prediction of spring flood rates and the contribution to water reservoirs in Hydro-power production. By establishing the relationship between accumulation patterns and physical parameters in the landscape such as topographic features and vegetation, a model of accumulation patterns in different types of reference areas can be produced. However, detailed information on the spatial and temporal evolution of the snow pack is necessary in order to develop such an algorithm. By determining the frequency and amplitude of topography in the Swedish mountain regions and by measuring snow accumulation in these regions we can increase the accuracy of the estimation of SWE. This information can then aid the understanding of scaling issues over the region. Satellite imagery and products can then be used for up-scaling from high-resolution field data to derive new satellite algorithms in the future.
