Edit Model information

GOLEM

Metadata

Also known as
Model type	Single
Model part of larger framework
Note on status model
Date note status model

landscape evolution,

Supported platforms	Unix, Linux, Mac OS
Other platform
Programming language	C
Other program language
Code optimized	Single Processor
Multiple processors implemented
Nr of distributed processors
Nr of shared processors
Start year development	1991
Does model development still take place?	Yes
If above answer is no, provide end year model development
Code development status
When did you indicate the 'code development status'?
Model availability	As code
Source code availability (Or provide future intension)	Through CSDMS repository
Source web address
Source csdms web address
Program license type	GPL v2
Program license type other
Memory requirements	Variable
Typical run time	minutes to days

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.

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.

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)

Do you have current or future plans for collaborating with other researchers?	--

Is there a manual available?	Yes
Upload manual if available:
Model website if any	http://geode.colorado.edu/~gtucker/Software/Golem/GolemMain.html
Model forum / discussion board

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.

This part will be filled out by CSDMS staff

OpenMI compliant	No but possible
BMI compliant	No but possible
WMT component	Not yet"Not yet" is not in the list (Yes, In progress, No but possible, No not possible) of allowed values for the "Code CMT compliant or not" property.
PyMT component
Is this a data component
