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. | 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.

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). | Simulation of a pair of normal-fault blocks separated by a vertical fault.
