Polynomial and power functions for glacial valley cross-section morphology

Auteur(s) et Affiliation(s)



Description :
An empirical evaluation of glacial trough cross-section shape is performed on seven vertical cross-sections in three Sierra Nevada valleys glaciated during the late Quaternary. Therefore, this study utilizes a datum at the upper valley wall where lateral moraines, trim lines or erratics can provide a clear limit to the glacial extent based on field evidence. This datum is referenced to coordinates of zero in the horizontal direction and elevation above sea level in the vertical dimension.
