Summary Contact Technical specs In/Output Process Testing Other Component info Also known as COLT v2.0 (following CoLT v1.0 at https://csdms.colorado.edu/wiki/Model:Coastal_Landscape_Transect_Model_(CoLT)) Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 1D Spatial extent Landscape-Scale Model domain Coastal, Ecosystems One-line model description Geomorphic and carbon evolution of a bay-marsh-forest coastal transect with restorations Extended model description A transect spanning three coastal ecosystems (bay-salt marsh-forest) evolves in yearly timesteps to show the evolution of the system. Geomorphic and carbon cycling processes allow for the exchange of material between the adjacent ecosystems. Each landscape unit is on the order of kilometers. Salt marsh restorations including sediment nourishment and shoreline stabilization can be turned on or off and modify geomorphic and carbon processes. Main geomorphic processes are featured in Kirwan et al. (2016) in Geophysical Research Letters, and carbon processes that track allochthonous and autochthonous carbon with time and depth are featured in Valentine et al. (2023) in Nature Communications.

Yes If above answer is no, provide end year model development Code development status As is, no updates are provided When did you indicate the 'code development status'? 2024 Model availability As code Source code availability (Or provide future intension) Through web repository Source web address https://github.com/mbbarksdale/CoLT_Restorations Source csdms web address Program license type GPL v3 Program license type other Memory requirements Typical run time Full model - 0.5-1 hr for a 100 year model run on a standard desktop computer Describe input parameters Initial rate of sea-level rise at start of spinup (mm/yr); rate of sea-level rise at end of spinup/start of model run (mm/yr); upland slope (m/m); suspended sediment concentration (external supply) (mg/L); length of simulation (years); rate of sea-level rise acceleration (mm/yr/yr); sill on (yes or no); percent of sediment settling behind sill (%); delay in sill placement (years); thin-layer placement on (yes or no); thin-layer placement thickness after consolidation (cm); thin-layer placement frequency (years); delay in thin-layer placement (years); erosion coefficient, Ke (dimensionless) Input format Other input format Excel spreadsheet Describe output parameters organic (allochthonous and autochthonous) and mineral deposition, bay extent, forest extent, marsh extent are the primary outputs Output format Other output format .mat files 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 Bay, marsh, and forest evolution on a coastline. Simulates marsh edge erosion, bay depth changes with wind waves, and marsh migration into coastal forests, and the carbon processes associated with these changes. Restorations, when turned on, modify erosion and accretion processes and subsequent carbon storage/decomposition. Describe key physical parameters and equations Describe length scale and resolution constraints Transect model with landscape of ~10 km (5 km bay, 1 km marsh, and 4 km forest in base version), 1 m grid scale horizontally. Describe time scale and resolution constraints 1 year time steps, good results up to 200-300 years Describe any numerical limitations and issues 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? No Is there a manual available? Yes Upload manual if available: Media:README COLT-Restorations Model User Guide.pdf Model website if any Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No not possible BMI compliant No not possible WMT component No not possible PyMT component No not possible Is this a data component No Can be coupled with:
