Channel-Hillslope Integrated Landscape Development (CHILD) Model
CHILD was originally developed in 1997 by Nicole Gasparini, Stephen Lancaster, and Greg Tucker, in a research group directed by Rafael Bras at the Department of Civil and Environmental Engineering at MIT. Development and use of CHILD continues, with contributions by (among others) Mikael Attal (Edinburgh), Patrick Bogaart (Wageningen), Quintijn Clevis (Oxford), Daniel Collins (Wisconsin), Arnaud Desitter (Oxford), Homero Flores (MIT), Erkan Istanbulluoglu (Nebraska), Scott Miller (Syracuse), Vanessa Teles (IFP), and the original developers.
Fault block uplift and subsidence
Simulation of a pair of normal-fault blocks separated by a vertical fault. The lower left edge is fixed through time, and represents a shallow shelf just below sea level. The inner block of the landscape rises at a steady rate, while the outer block subsides. Initially, the relief and erosion rate are small, and the subsiding basin is underfilled. Notice the progradation of a fan-delta complex. As relief and sediment flux increase, the fan deltas reach the shallow shelf and the basin becomes filled (or "over-filled" as they say, meaning that there is more than enough sediment to keep filling the basin as it continues to subside).

Version R10.7 has been released! Included with this version is a set of hands-on, tutorial-style exercises that were "beta tested" at the "Summer School and Workshop on Modelling Surface Processes on Geological Timescales" in Davos, Switzerland, in June 2010. Space-time varying uplift fields can now be specified -- see the Users Guide for details.

Philippe Steer reports:
I am Philippe Steer, PhD student at Geosciences Montpellier in France.
I have encountered an error when trying to compile child:
"INT_MAX" was not declared in this scope /Code/tMesh/tMesh.cpp
Solution to this problem:
add "#include <limits.h>" at the begining of tMesh.cpp
OS: linux- Opensuse11 Computer: Dell Precision T 7400, Intel Xeon, 64 bits compiling with gcc 4.3
I hope it will help other newbies (as I am!) in C,
A new manual is now available.
