Soil erosion investigations, Narromine and Gilgandra – November 2024 to March 2025

Our crews will return to site on 20 January 2025 to undertake soil erosion investigations at multiple locations around Narromine and Gilgandra. Known as Erosion Threshold Velocity testing, these investigations test soil erodibility in flood-prone areas.

Date

November 2024 - March 2025

Working hours

7am to 6pm Monday to Saturday, with work occurring every second Sunday. Work will happen every day for 10 days followed by a four-day break.

Location

Various locations

Town
  • Narromine
  • Gilgandra
Local Government Area
  • Narromine Shire Council
  • Gilgandra Shire Council

Work being done

Work will include:

  • Superficial soil sampling and testing on site using hand tools
  • Undisturbed soil sample collection involving pushing sampling frames with a small excavator through a small trench to collect samples with an ‘undisturbed’ surface for testing in a laboratory.

What can I expect?

  • Site supervision vehicles, a small excavator and accompanying flatbed truck/trailer operating onsite or accessing work sites
  • Nearby residents may experience some daytime noise
  • At locations where sample collection will disturb the ground surface, areas will be backfilled at the completion of work (same day).

Machinery used

Small excavation equipment (5-tonne excavator or smaller), had tools, support vehicles, traffic management equipment and signage.

How we're managing impacts

  • Traffic management will be in place to ensure safe access for all road users if works are required in the road corridor.
  • Reduced road speeds in the vicinity of work areas if required
  • Regular contact with impacted landowners to discuss site activity and any land access requirements.

Contact

For any concerns or enquiries please phone 1800 732 761 or email inlandrailnsw@inlandrail.com.au

Thank you for your patience and cooperation while we carry out these works.

What is Erosion Threshold Velocity testing?

Erosion Threshold Velocity testing is a study of soils, to determine whether they could possibly be eroded by overland water flows. This fact sheet explains how and why Inland Rail uses this form of testing and includes a step-by-step explanation of the testing process.
