Abstract

The morphometry of glaciated valleys has been of considerable significance in evaluating models and processes of valley form development, and is typically evaluated using a power law function fit to topographic data. Results of the power law method are sensitive to the location of the coordinate system origin, but most previous research has used a coordinate system centered on the valley midpoint and has not systematically assessed alternative approaches. Here, the AA. test 4 options for selecting the coordinate system origin, using cross-section profiles from glacial, fluvial, and transitional valleys in the Dalijia Mountains, China. In conclusion, in morphometric studies designed to evaluate impacts of glacial erosion using the power law approach, the AA. recommend that alternate coordinate system origins be evaluated, including the lowest elevation point on a cross-profile
