Abstract

This study investigates climate change over glacial time scales by comparing the modern and full-glacial extents of valley glaciation in the central Himalaya and estimating the relative climate changes they imply. To map full-glacial extents, the AA. adapt traditional field- and map-based geomorphic methods for use with a 90 m resolution digital elevation model (DEM) within a geographical information system (GIS). They analyze the valley morphology of the drainage network of central Nepal, using cross-valley form and slope angle statistics to discriminate between glacial and fluvial valleys. For both full-glacial and modern cases, ELA depressions are computed from the glacier limits using the DEM and a toe-to-headwall altitude ratio of 0.5
