|Describe time scale and resolution constraints=The steady flow assumption used by most (not all) hydrology sub-models restricts time scale to periods significantly longer than a single storm. The model has been mostly used to address time scales relevant to significant topographic evolution, though in the case of rapidly changing landscapes (e.g., gully networks) this can be as short as decades. | |Describe time scale and resolution constraints=The steady flow assumption used by most (not all) hydrology sub-models restricts time scale to periods significantly longer than a single storm.

|Describe any numerical limitations and issues=The fluvial sediment transport equations are quasi-diffusive and typically have orders of magnitude spatial variations in rate coefficient (reflecting differences in water discharge), which makes the system of equations stiff and difficult to solve efficiently. | |Describe any numerical limitations and issues=The fluvial sediment transport equations are quasi-diffusive and typically have orders of magnitude spatial variations in rate coefficient (reflecting differences in water discharge), which makes the system of equations stiff and difficult to solve efficiently. | ||

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.

Channel-Hillslope Integrated Landscape Development (CHILD) ModelCHILD 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. Example SimulationsFault block uplift and subsidence<localvideo width="200" height="150" image="Child_Fault_Basin_4m.png" caption="Fault block uplift and subsidence" type="video/msvideo"> Child_Fault_Basin_4m.avi </localvideo> 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). Evolution of river valley landscape, stratigraphy, and geoarchaeologyScenario 1: Steady Aggradation
Scenario 2: Pomme de Terre River incision/aggradation history
Scenario 3: incision/aggradation history based on oxygen isotope curve
