Simulating Glacial Erosion Using Landscape Evolution Code
Chelsea Willett EPS 109 Fall 2014 Slide 2 Perron et al., 2008 (on
bCourses) Modify parameters to generate U-shaped valleys: K=1x10 -6
m (1-2m) /yr D=0.003 m 2 /yr m=1.05 (area exponent) n=1.1 (gradient
exponent) U=0 (uplift resulted in unstable edge effects) c =1 Test
on simplified landscape (Gaussian valley) Apply to real topographic
data (Andes) Discretized PDEs Slide 3 Run GlacialErosion.m and
select desired initial landscape conditions (lines 14-32) Gaussian
valley Slide 4 Run GlacialErosion.m and select desired initial
landscape conditions (lines 14-32) Central Andes
