SIBERIA Capabilities (V8.30, October, 2005)


Process

Details

 

Fluvial Erosion

   Transport limited based on sediment diameter with tracking of diameter in eroded/deposited sediment and re-entrainment of eroded sediment. Detachment limitation on transport capacity. Sediment characteristics space varying (see Layers below).

V8.30

 

   True sediment tracking for cosmogenic nuclide and pollutant tracking.

Early 2006

Mass Movement

   Nonlinear diffusive transport with Ahnert slope threshold.

V8.30

 

   Event scale simulation of landslides and debris flows.

2007

Climate

   Incorporated through effective parameterisation of fluvial erosion that yields average annual erosion. Spatially variable rainfall.

V8.30

 

   True climate input (known or stochastic).

Mid 2006

Hydrology

   Simple empirical regional flood frequency relationship, or runoff coefficient, based on area.

V8.30

 

   Runoff event simulation based on input climate (see Climate above).

Mid 2006

Soils

   Generalised Heimsath model

V8.30

Vegetation

   Cover factor as per USDA erosion models

V8.30

 

   Stochastic bushfire model for groundcover removal

Mid 2006

Tectonics

   Time and spatially varying vertical only uplift.

V8.30

 

   Lateral strike/slipe and lateral deformation

No

Layers

   Spatially varying layers of materials (e.g. geology strata, containment capping layers) with tracking of the movement of these materials by fluvial erosion

V8.30

 

   Ditto for existing mass movement model.

Mid 2006

 

   Dynamic management of layers of deposited materials and their characteristics

V8.30

Computational

   D8 and d drainage analysis on a square grid (cant do rectangular grid, for instance, SRTM data w/o regridding)

V8.30

 

   Standards based (openMP, PVM) parallel processing on clusters and multiprocessor supercomputers

Temporarily unavailable

 

   Highly portable code (F95)

V8.30

 

   Can be run with and w/o GUI interface (for batch processing)

V8.30

 

   GIS like input of time and space varying capabilities (not ARC shape files)
