| | class="model_col1"| Model type:
| |
| | class="model_col2"| Modular model for the terrestrial domain.
| |
| |-
| |
| | class="model_col1"| Description:
| |
| | class="model_col2"| 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.

| ==== Process description ====
| | === Subversion Help === |
| | |
| {| class="wikitable"
| |
| | class="model_col1"| Processes represented by model:
| |
| | class="model_col2"| 2d multiple flow direction steady state flow model<br>Erosion and deposition over 9 separate grainsizes<br>Bedload and suspended load sediment transport<br>Slope processes (creep, enhanced creep and mass movement)<br>Vegetation growth<br>Aeolian transport (under development - slab dune model)
| |
| |-
| |
| | class="model_col1"| Key physical parameters & equations:
| |
| | class="model_col2"| Flow depths calculated using version of mannings implemented across a cellular grid using a scanning algorithm.<br>Sediment tranport using either Einstein or Wilcock and Crowe functions<br>Slope model using simple slab failure and psuedo USLE implementation<br>Dune model adaption of DECAL and Werner slab model
| |
| |-
| |
| | class="model_col1"| Length scale & resolution constraints:
| |
| | class="model_col2"| Has been applied to catchments ranging from 1km^2 to 500km^2, at grid resolutions ranging from 1m to 50m.
| |
| |-
| |
| | class="model_col1"| Time scale & resolution constraints:
| |
| | class="model_col2"| The model has simulated periods from 1 day to 9000 years.<br>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.
| |
| |-
| |
| | class="model_col1"| Numerical limitations and issues :
| |
| | class="model_col2"| Run times can be long (60 +days for large areas over many 100's of years).<br>Flow model is steady state
