Case Study: Wollongong City Council stabilises an eroding creek with 12d Model

Wollongong City Council - Customer Case Study

ollongong City Council faced significant challenges in stabilizing an eroding creek in Thirroul, NSW. The erosion was severe, site access was difficult due to unstable banks and surrounding landforms, and the project was complicated by constant water flow, the presence of significant trees, a high potential for debris, and the need to quantify hydraulic impacts. The council engaged 12d Solutions and utilized their 12d Model software to address these complex issues.

Using 12d Model's 3D design and terrain analysis tools, the team developed a comprehensive solution. This included identifying the root cause of the erosion, designing a stable two-stage filling regime that doubled as a construction access track and flow diversion, and precisely modeling the site to protect trees and manage debris. The solution enabled the project to be completed cost-effectively by minimizing risks, avoiding unnecessary excavation, preserving existing vegetation, and ensuring the design was hydraulically sound. The work by 12d Solutions provided the council with a stabilized creek and a permanent, low-maintenance solution to prevent future erosion.
