Landscape Evolution Modeling ERODE Irina Overeem, February 2013

Early Landscape Evolution Model Gilbert, 1877, ‘The Geology of the Henry Mountains’ Gilbert describes weathering, erosion processes and shifting of drainage divides and waterways in Utah mechanistically.

Landscape Evolution Model Definition: mathematical theory describing how the actions of various geomorphic processes drive the evolution of topography over time. Reference: Tucker & Hancock, Modelling landscape evolution. Earth Surface Processes and Landforms HillslopesStream and River Transport

Components to Landscape Evolution Model Formulations for: 1)Continuity of mass 2)Runoff generation and Routing of water 3)Erosion-Transport laws for hillslope sediment 4)Erosion - Transport laws for river sediment

Raster Model Any cell receive water and mass flux from ‘upstream’ cells, so we need to know drainage pattern

‘D8 Algorithm’ for Drainage COI We assume that water and mass flows into the direction of the steepest slope: S = slope[-] Δz= z_coi – z_neighbor[L] d = distance[L] What are the lengths, d, for the two potential drainage directions?

D8 Grid for Entire DEM Assumption: The grid cell size is chosen to be smaller than the hillslope scale and larger than the width of the largest channel. Every grid cell then has ‘one channel’ associated with it that extends from the centre of the grid cell to the centre of the grid cell that it flows to according to the D8 method.

Continuity Equation in ERODE TROC of mass = mass rate in – mass rate out If the entire cell would be impacted by tectonic uplift (U):

Runoff Equation of ERODE Q = water transport rate [L 3 /T] R = rain rate [L/T] A = contributing area[L 2 ] p = Q-A coefficient [-]

Sediment Transport Equation in ERODE Qs = sediment transport rate [L 3 /T] K = erodibility Q = water discharge [L 3 /T] S = slope [-] m = discharge coefficient [-] n = slope coefficient [-]

Output: Elevation Grids over Time T ~ 200,000 years T ~ 9,000,000 years

Output: Contributing Area Grids

Adaptive Time-Stepping CLF criterion Courant-Friedrichs-Lewy Condition A condition in numerical equation solving which states that, given a space discretization, a time step bigger than some computable quantity should not be taken.
