Dundee Boat Ramp

Infrastructure Consulting was engaged by Advance Civil Engineering on behalf of the Department for Logistics and Infrastructure to undertake review, assessment and design of upgrades to the Dundee Beach Boat Ramp.

In collaboration with our project partners, Baird, we undertook a review of the previous coastal modelling and assessed the wave climate and sediment transport environment at the site.

The Problem

The location of the site presents a unique challenge, with exposure to long fetches, reversal of sand flows between wet and dry season, and exposure to extreme cyclonic conditions. The geology of the location also presents a broad, shallow shelf hampering access to deep water.

The study identified that the prevention of sand buildup in the current location was not economically feasible.

The Solution

Our team proposed modifications to the existing groyne to reduce cut-through and over topping of sand traveling from North to South. We also proposed operational and maintenance regime changes to better manage the accumulation of sand from the South and address a back-eddy effect identified.

The works to the groyne were integrated with infrastructure upgrades to provide a boat launching ‘jetty’, accessible footpaths to the groyne, and large fishing platform at the end of the groyne.
