What Swash did

  • Swash provided innovative design and advisory services for strategic assessment of sand management and dredging options at Manning River Entrance.

About the project

The entrance to the Manning River includes two openings, one at Harrington to the north and one to the south, the Farquhar entrance at Old Bar. The Manning River experiences a high level of shoaling at Harrington, which can restrict safe access for vessels.

A reliable and permanent river entrance would improve safety for commercial and recreational boat users, and increase use of the river and investment opportunities throughout the Manning Valley.

The Manning River Taskforce looked at options for a permanent safe entrance to the Manning River for vessels.

The Taskforce included experts in coastal engineering, maritime infrastructure, coastal management, and maritime industry and was led by Transport for NSW.

Potential options have been considered over the years including construction of a new breakwater, routine dredging and stabilisation of the Manning Point with an artificial sandspit by using large sandbags.

A strategic business case was undertaken to provide decision makers with information on whether this project will progress to the next phase of a final business case.
