Deposition Modelling

Rift TD is an advanced three-dimensional Digital Terrain Model specifically developed to model tailings deposition. It is a powerful tool that facilitates tailings storage facility:

  • options assessment/site selection
  • conceptual and detailed design
  • deposition planning
  • operation and management
  • water management

Use Rift TD to model:

  • upstream;
  • downstream; and 
  • centreline deposition.

Its features include:

  • Deposition to known tonnage(s)
  • Target maximum tonnage
  • Supernatant pond modelling to a known volume or elevation
  • Varying cylone, sub-aerial and sub-aqueous beach profiles
  • Non-linear beach profiles
  • Google Earth (kml) export
  • Deposition from:
    • Nodes
    • Lines
    • Paths
  • Deposition points that move in space
  • Tailings flow down valleys and around obstacles
  • Fully developed tailings stage capacity curves at user defined elevation increments
  • Detailed deposition results for each:
    • Deposition lift
    • Deposition location

You can automatically save deposition images during a model run and use them to generate videos showing facility development.

Rift TD Environment

DTM Functionality

Rift TD has significant digital terrain modelling functionality, including string support. Use Rift TD to:

  • Generate toe points from a string
  • Generate nodes along a string
  • Triangulate nodes to form surfaces
  • Calculate volumes between surfaces
  • Merge models


Rift TD is independent and not reliant on other software.

  • Import data points from DXF, csv or text files and triangulate them to generate surfaces
  • Export data to DXF, csv or text files for import into other software
  • Copy data or graphics to the clipboard and paste them into other software
  • Save graphics to files for presentation or import into other software

Google Earth

Rift TD allows you to export your surfaces to Google Earth (kml). This allows you to view surfaces in location.
