  1. Cross-Sectional Erosion EPS 109 Aaron Yang

  2. Equations/Methods • Compared/related various lowering rates, dependant on heights/position • Updated initial surfaces with an update function • L(soil) = (Pc*Vc)/(Ps*As*T) • Used PDE in order to simulate lateral diffusivity • D*((z2(i+1)-2*z2(i)+z2(i-1))/((1)^2) • Diffusivity constant based on Heismath (1997)

  3. Example 1 Run with ErosionProject.m All units in meters

  4. Example 2 Faster exaggerated lateral diffusivity for soil
