Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Blocky Landscape Evolution Model Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Landscape-Scale, Reach-Scale, Watershed-Scale Model domain Terrestrial One-line model description BlockLab computes landscape evolution in the presence of large blocks of rock on hillslopes and in channels. Extended model description Blocklab treats landscape evolution in landscapes where surface rock may be released as large blocks of rock. The motion, degradation, and effects of large blocks do not play nicely with standard continuum sediment transport theory. BlockLab is intended to incorporate the effects of these large grains in a realistic way.

No If above answer is no, provide end year model development 2018 Code development status As is, no updates are provided When did you indicate the 'code development status'? 2020 Model availability As code Source code availability (Or provide future intension) Through web repository Source web address https://github.com/cmshobe/BlockLab Source csdms web address Program license type Other Program license type other MIT Memory requirements more is better; will work on a laptop w/ 4 GB RAM Typical run time hours to days Describe input parameters Input format Other input format Describe output parameters Output format Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Describe processes represented by the model Cliff failure and retreat; hillslope evolution; river erosion; block release, transport, and weathering. Describe key physical parameters and equations River and hillslope erosion coefficients, hillslope weathering parameters; initial block size, block release/motion thresholds, block weathering rate. Describe length scale and resolution constraints Standard LEM constraints on length scale: reach scale and above until you run out of computing power. Resolution is constrained by block size, should generally be order 1-10 m. Describe time scale and resolution constraints Timesteps in the range of 1-10 years are generally stable, can run for as long as desired until the memory runs out. Describe any numerical limitations and issues Becomes unstable at timesteps much greater than 10 years. Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Upload test data sets if available: Describe ideal data for testing Do you have current or future plans for collaborating with other researchers? Is there a manual available? No Upload manual if available: Model website if any Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component No but possible PyMT component Is this a data component Can be coupled with:
