Introduction to MINErosion 3

• MINErosion 3 was funded by ACARP with the
  objectives
• Development of a user-friendly package that
  allows Env Officers to
• -rapidly assess potential for erosion on sites
  of interest.
• -determine suitable landscape parameters of
  slope length and
• gradients that will result in acceptable
  erosion rates.
• Develop a total package that provides a sound
  introduction to
• erosion processes and how erosion is
  monitored, parameterized
• and modeled.
• Develop the package as a suitable educational
  package. It should
• provide a refresher course to practitioners who
  use the package
• occasionally.

• History of the package
• Work was inititiated in 1992 with the project
• Postmining Landscape Parameters for Erosion
• and water Quality control
• 1998 project was completed.
• Outcomes relevant to the mining industry were
• Database of 34 soil and spoil properties
• MINErosion 2.2 links lab based measurements to
  field processes
• PGM (Perfect-Grasp-Musle) module landscape
  design module
• based on 12 m long field rainfall simulation
  plots.

• However adoption of technology was limited due
  to
• difficulty in using them not adequately user
  friendly
• local knowledge lost due to rapid movement of EOs

• Additional issues that requires resolution
• How can erosion be readily monitored as rehab
• progresses?
• What is the rate of erosion after consolidation
  and
• after the mine is decommissioned ?

• Clearly rapid monitoring is desirable and will
  have to be
• done using small rainfall simulator and
  laboratory
• analysis.
• Therefore, further development of MINErosion
  seems
• a logical way to proceed.

This is the main screen showing calculations of
sediment delivery rates from selected slopes
under constant rainfall and is calculated using
the MINErosion model. Explanation of this model

Validation of mean annual soil loss
Note Kidston data Data from PLPEWC
project (Curragh and Oaky Creek Mines
at 20
slope) Annual soil loss from Curragh and Oakey
Creek were averages of 4 consecutive years, while
data from Kidston Goldmine was from a one year
observation.
