CHILD Model

The CHILD model is widely used for the simulation of landscape evolution.

CHILD (Tucker and Bras, 1998; Tucker et al., 2001a,b) computes the evolution of topography and stratigraphy in response to a wide range of processes closely related to landscape evolution such as various representations of runoff, erosion and sediment transport by gravitational, fluvial, regolith production, and tectonic perturbation. Based on an adaptive irregular mesh, CHILD is capable of simulating detachment and transport limited sedimentation mechanisms, meandering and flood plain deposition. The model accounts for the interaction between vegetation and water erosion using a vegetation growth and damage algorithm.
