“…It accounts for convex-upward hillslope profi les, and has been tested and calibrated using cosmogenic nuclide mass-balance measurements (McKean et al, 1993;Heimsath et al, 1997Heimsath et al, , 2001Heimsath et al, , 2005Small et al, 1999). The creep function has been widely applied to scarp degradation, including fault scarps and fl uvial, marine, and lake-shore terraces (Colman and Watson, 1983;Hanks et al, 1984;Andrews and Hanks, 1985;Andrews and Bucknam, 1987;Avouac, 1993;Avouac and Peltzer, 1993;Rosenbloom and Anderson, 1994;Arrowsmith and Rhodes, 1994;Enzel et al, 1996;Arrowsmith et al, 1998;Niviere et al, 1998;Hanks, 2000;Font et al, 2002;Phillips et al, 2003;Hsu and Pelletier, 2004;Kokkalas and Koukouvelas, 2005;Nash and Beaujon, 2006;Pelletier et al, 2006). Estimates of the rate coeffi cient K c have been obtained from a variety of approaches (see compilation by Martin and Church, 1997).…”
