Multi-Material Deposition

Rift TD deposition is sequential, moving from one deposition point to the next.

For multi-material deposition, material throughput is distributed between deposition vectors in the same deposition sequence i.e. that have the same deposition order.

Fill times for deposition from a particular deposition vector are calculated using:

Fill volume.

Material density.

Material throughput.

During simultaneous deposition this may result in some areas filling faster than others.

If this occurs, to maintain the material balance:

Throughput is re-distributed to other deposition vectors/locations to maintain the material balance; use the Result Detail Form to view the material re-distribution.

The complex beach profile defined by the deposition vector is used to generate the deposited surface i.e. the complex beach profile defined for the material being re-distributed is not considered.

For upstream cyclone deposition, cyclone tailings is distributed using the underflow percentage for the material being deposited/re-distributed i.e. not the percentage underflow for the material specified by a deposition vector.

The entire tailings stream (all materials) is deposited by a single deposition vector if a sequence contains only one deposition vector.


Deposition changes the base topography.

Earlier deposition may impact significant on deposition later in a deposition sequence/cycle.
