| Code optimized | Single Processor |
| Start year development | 1991 |
| Does model development still take place? | Yes |
| If above answer is no, provide end year model development | |
| Model availability | As code |
| Source code availability (Or provide future intension) | Through owner |
| Source web address | |
| Program license type | GPL v2 |
| Program license type other | |
| OpenMI compliant | No but possible |
| CCA component | No but possible |
| IRF interface | No but possible |
| Memory requirements | Variable |
| Typical run time | minutes to days |
| Input - Output description | |
|---|---|
| Describe input parameters | Standard input parameter files (ascii). For some conditions, also require additional binary file specifying boundary configuration. |
| Input format | ASCII, Binary |
| Other input format | |
| Describe output parameters | Elevation, drainage area, and related gridded information. |
| Output format | ASCII |
| Other output format | |
| Pre-processing software needed? | No |
| Describe pre-processing software | |
| Post-processing software needed? | No |
| Describe post-processing software | |
| Visualization software needed? | Yes |
| If above answer is yes | IDL, Matlab |
| Other visualization software | some visualization scripts for IDL and Matlab available. |
| 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. |
| Model testing | |
|---|---|
| Describe available calibration data sets | Few or none, unfortunately |
| Upload calibration data sets if available: | |
| Describe available test data sets | -- |
| Upload test data sets if available: | |
| Describe ideal data for testing | See paper on geomorphic natural experiments by Tucker (in review, 2008) |
| Users groups model | |
|---|---|
| Do you have current or future plans for collaborating with other researchers? | -- |
| Documentation model | |
|---|---|
| Provide key papers on model if any | Papers:
|

| Upload manual if available: | |
| Model website if any | http://www.colorado.edu/geolsci/gtucker/Software/Golem/GolemMain.html |
| Model forum / discussion board | |
| Additional comments | |
|---|---|
| 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. |
