Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Modular Model part of larger framework Note on status model Date note status model Spatial dimensions Spatial extent Model domain Terrestrial One-line model description Cellular landscape evolution model Extended model description CAESAR is a cellular landscape evolution model, with an emphasis on fluvial processes, including flow routing, multi grainsize sediment transport. It models morphological change in river catchments. Keywords: landscape evolution, Name Tom Coulthard Type of contact Model developer Institute / Organization University of Hull Postal address 1 Cottingham Road Postal address 2 Town / City Hull Postal code HU6 7RX State NO STATE Country United Kingdom Email address T.Coulthard@hull.ac.uk Phone Fax Supported platforms Linux, Windows Other platform Programming language C Other program language C# Code optimized Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 1996 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, As teaching tool Source code availability (Or provide future intension) Through web repository Source web address http://www.coulthard.org.uk/downloads/visualcaesar.htm Source csdms web address Program license type Other Program license type other GNU Memory requirements >512MB Typical run time 5 min to 50 days Describe input parameters DEM as ascii grid (output from arcGIS), Rainfall data as a space separated ascii file (straightforward list), Inputs of water/sediment in an ascii file. Other single value parameter inputs for grainsize, flow parameters, slope processes etc.. Input format ASCII Other input format Describe output parameters ascii grids (readable into arcGIS) and google earth images of: DEM, flow depth, surface grainsize, shear stress, vegetation cover, velocity. Also time series of water discharge and sediment discharge (across 9 grainsizes) at user chosen interval. Also visual output to AVI file. 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? No If above answer is yes Other visualization software Describe processes represented by the model 2d multiple flow direction steady state flow model Erosion and deposition over 9 separate grainsizes Bedload and suspended load sediment transport Slope processes (creep, enhanced creep and mass movement) Vegetation growth Aeolian transport (under development - slab dune model) Describe key physical parameters and equations Flow depths calculated using version of mannings implemented across a cellular grid using a scanning algorithm. Sediment tranport using either Einstein or Wilcock and Crowe functions Slope model using simple slab failure and psuedo USLE implementation Dune model adaption of DECAL and Werner slab model Describe length scale and resolution constraints Has been applied to catchments ranging from 1km^2 to 500km^2, at grid resolutions ranging from 1m to 50m. Describe time scale and resolution constraints The model has simulated periods from 1 day to 9000 years. The length of run is largely contingent on the number of grid cells, thus a balance between resoltion and area of study. A small catchment with a coarse resolution will run very fast. Increase the area or make grid cells smaller and run times will increase. Describe any numerical limitations and issues Run times can be long (60 +days for large areas over many 100's of years). Flow model is steady state Describe available calibration data sets Tested on several catchments in UK over long and short time scales. Upload calibration data sets if available: Describe available test data sets none yet; in development Upload test data sets if available: Describe ideal data for testing Flow and sediment discharge data, images of topographic change Do you have current or future plans for collaborating with other researchers? Yes, I am happy to collaborate with any potential users. There is a long history of CAESAR being take up by others including researchers in Italy, France, Spain, NZ, Australia, USA. Is there a manual available? Yes Upload manual if available: Model website if any http://www.coulthard.org.uk 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:
