Darwin River Dam survey

Client: Power and Water Corporation (PWC)

Mapping and 3D modelling Darwin River Dam

Darwin River Dam was opened in 1972 and is the major water source for the city of Darwin.

The Dam is an embankment type dam estimated to hold up to 259,000 megalitres of water - half the volume of Sydney Harbour, and 11 times bigger than Manton Dam.

Rise undertook a bathymetric survey of the entire reservoir to model the reservoir bed providing PWC with accurate reservoir volumetrics to model the impact of changing water levels.

Rise also provided industry leading visualisation of the Inlet Tower (digital twin and underwater ROV inspection); Dam embankment (orthomosaic mapping) to allow PWC to undertake comprehensive inspections.

During the survey works Rise was also able to identify and map various submerged hazards within the reservoir (telegraph poles, old railway tracks).

The survey works were carried out during the tropical wet season over 5 stages using Rise’s 5.6m rib

Technology for the North, designed in the North

We are so proud to have our investment into the development of a tropical bathymetric USV (unmanned service vehicle) secure matched funding from Advanced Manufacturing Growth Centre Ltd. Current wastewater survey methods are often not fit-for-purpose for the waste water conditions in tropical Northern Australia - high debris loads and organic matter.
