{{Input - Output description | |||
|Describe input parameters=Standard input parameter files (ascii). For some conditions, also require additional binary file specifying boundary configuration. | |||

{{Process description model | |||
|Describe processes represented by the model=Runoff, hillslope and channel sediment transport. | |||
|Describe key physical parameters and equations=Key state variables include surface elevation, soil thickness, and discharge. | |||
|Describe length scale and resolution constraints=Has been used on scales from small (few km2) watersheds to sub-continental areas. | |||
|Describe time scale and resolution constraints=Designed for time scales over which topography changes appreciably, which might be years for badlands, up to thousands or millions of years for other landscapes. | |||
|Describe any numerical limitations and issues=Equation set is still and uses robust but relatively inefficient solvers. Recommend testing with coarse grid resolutions (say, 20x20 cells) before attempting larger/finer grids. | |||

{{Additional comments model | |||
|Comments=GOLEM was written in the 1990s by one of the creators of CHILD. Although it lacks many of the special capabilities of CHILD, it has a simpler, more compact code base (just a single C source file) and uses a raster grid data structure. | |||
