Regional analysis of bedrock stream long profiles : evaluation of Hack's SL form, and formulation and assessment of an alternative (the DS form)

Description :
The Hack SL form of the long profile, which describes a straight line on a log-normal plot of elevation (normal) versus distance (logarithmic), is the equilibrium long profile form that has been most widely used in such studies. The AA. show that the SL form is a special case of a more general form of the equilibrium long profile (here called the DS form) that can be derived from the power relationship between stream discharge and downstream distance, and the dependence of stream incision on stream power. The DS form provides a better fit than the SL form to river long profiles in an intraplate setting in southeastern Australia experiencing low rate of denudation and mild surface uplift.
