Key takeaways from our most recent webinar with Cameron McNaughton from RWDI

We would like to thank Cameron McNaughton from RWDI for his presentation on how critical it is to understand and manage dust emissions for environmental performance in arid and disturbed landscapes.

This webinar explored why traditional approaches fall short and how new measurement techniques are improving confidence in dust risk assessments.

Key takeaways:

• Dust emissions are natural but are amplified by land disturbance and poor surface management.
• Common modelling methods are conservative and often over estimate emissions, particularly for managed sites.
• Wind erosion is highly variable, driven by surface material, moisture, disturbance, and wind conditions.
• In situ measurements provide more accurate and defensible estimates than modelling alone.
• The PI SWERL system offers a practical way to directly measure dust emission thresholds and rates in the field.
• A South Australian mine study showed tailings had low long term wind erosion risk, with higher emission thresholds than surrounding natural surfaces.

If you were un-able to make the webinar, a recording of it is on our website, along with the library of all our past presentations. Enjoy!
