Mining / Geotechnical / Environmental Engineering Software

Three D ModelRift TD is a sophisticated digital terrain model specifically developed for modelling tailings dams and associated infrastructure, including embankments and ponds.

Rift TD allows the rapid assessment of various deposition scenarios and their impact on ponds, and the generation of staged earth-fill or time-staged cyclone embankment construction.

The software's capabilities include point, upstream, downstream and centreline deposition.

FEATURES [applications]

For examples of some of Rift TD's Tailings Deposition Modelling capabilities see our Tutorial page.

Stand Alone

Rift TD is a stand alone package. It is not dependent on other software.

Data is imported/exported in either ASCII or DXF (Release 12) files.

Non Linear Beach Profiles

Model non-linear cyclone, sub-aerial and sub-aqueous beaches based on an overall slope and dimensionless profile. The profile is either entered manually or generated based on Blight and Bentals dimensionless profile (ref. The Master Profile for Hydraulic Fill Beaches, Proceedings of the Institution of Civil Engineering, Jan 1994).

Cyclone Deposition

For Upstream Cyclone deposition Rift TD estimates the cyclone/sub-aerial beach interface based on the underflow/overflow percentage split.

Downstream and Centreline Cyclone Embankments are modelled in a staged approach, with construction end times being determined based on a User specified underflow percentage. This approach allows the User to ascertain embankment crest elevations over time. Following the development of the model it is possible to do "what if" scenario testing to determine the effect of the underflow percentage and/or material densities.

Tailings Flow

Model tailings flow down valleys or around obstacles.

Multiple Materials

Model the deposition of multiple materials from different locations around the facility. Stage capacity curves are generated for each of the materials as well as for overall deposition.

Multiple Deposition Points

Define multiple deposition points and or deposition lines.

Deposition lines are drawn on the screen, and represent physical boundaries along which deposition takes place. Deposition points are generated along the boundaries based on user entered criteria (either a fixed number of deposition points, or a spacing between points). The Tailings Facility Wall can be developed to differing elevations along the length of the wall.

Once entered the user can specify the deposition sequence, enabling simultaneous deposition from a number of deposition points. This is of particular relevance to models containing a number of deposition materials.

Manual or Automatic Deposition

The user has complete control of deposition.

In automatic mode the facility is completely developed based on user input.

In manual mode the user specifies deposition elevations at deposition points. Deposition takes place from the points based on the user specified sequence.

Pond Generation

Generate ponds, and their volume elevation curves, by simply pointing to a point in the pond basin and entering the top water level.

DTM Functionality

Rift TD has substantial DTM functionality:

Numerous tools are available for editing the model:

An embankment wizard facilitates the task of embankment modelling.
