ESTIMATION OF SNOW DEPTH DISTRIBUTION BASED ON SIMILARITY OF SNOW DEPTH DISTRIBUTION PATTERN

Abstract

 In water resource management and disaster prevention, it is very important to estimate snow depth distribution in the mountainous regions as accurately as possible before the snow starts to melt. To estimate snow depth distribution easily with high accuracy, we established a method to estimate it based on similarity of snow depth distribution pattern which measured by airborne laser scanning twice. As a result, the method produced the estimate of snow depth distribution with high accuracy in the dam basin.
