The scientific field of hydrology that is concerned with the composition, dispersion and movement of snow and ice is referred to as snow hydrology. Important hydrological processes include snowfall, accumulation and melt in watershed at high altitudes and latitudes. Snow melt is useful in many areas as it supplies water to reservoirs and populations, and is also used for agricultural activities. Snow hydrology provides knowledge which is used in weather forecasting. Information of snow composition and movement is gathered through density, depth and composition readings and by using various remote sensing techniques. This book outlines the processes and applications of snow hydrology in detail. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. It will serve as a valuable source of reference for graduate and post graduate students.
