Water Sciences

The integrated management of water resources and the sustainable care of marine and freshwater environments is important for the long term viability of a country’s resources.

Water managers must balance the economic, social and environmental demands associated with our wetlands, rivers, coastal and ocean environments.

GHD’s Water Sciences services combine our technical aquatic and marine capacity with our water engineering services to provide innovative, cost-effective water resource management solutions for our clients. 

Our global team of marine and aquatic scientists provide support to clients in the following services:

  • Biological and habitat assessment and monitoring including; benthic and epi-benthic invertebrates, marine pests, corals, seagrasses, mangroves, fish, mammals, seabirds, turtles, macroinvertebrates, diatoms, wetlands, macrophytes
  • Environmental impact and mitigation management
  • Biological assessments and monitoring
  • Water quality and sediment assessments and monitoring
  • Catchment and waterway inventories, assessments and rehabilitation
  • Wetland monitoring and rehabilitation including constructed wetlands
  • Fisheries management
  • Environmental flows

Blue Lake Pumping Station Modifications, SA Water

image

The existing Blue Lake Pumping Station was commissioned in the early 1970s to be the primary supply of water to Mount Gambier and the surrounding districts in South Australia.

The pumping station is located on the northern side of the Blue Lake and consists of a floating pontoon structure (that pumps water to the bank of the Blue Lake), a secondary pumping station and anchor block (that pump the water up to the top of the crater), and associated infrastructure.

GHD was engaged by the Central West (CW) and Border Rivers-Gwydir (BRG) catchment management authorities (CMAs) to study the distribution and management of Lippia in the Macquarie Marshes & Gwydir Wetlands.

Our work increased the CMAs' understanding of Lippia (Phyla Canescens) throughout the area, including the rate of spread, outbreak triggers and control measure successes.

Lake Condah Restoration project management

image

GHD was engaged to project manage the design and construction of infrastructure that would allow the restoration of Lake Condah, near Heywood in Victoria.

Lake Condah forms a key part of the recently declared Budj Bim National heritage landscape and is identified as a wetland of national significance, mainly based on cultural and ecological grounds. Eel trap systems developed by Gournditjmara people at Lake Condah and along the Budj Bim volcanic landscape are estimated to date back to 8000 years BC.

Murray River wetland rehabilitation

image

Known as the Wetland Rehabilitation Project – Reinstating Wetting and Drying Regimes, this is one of the first projects of its type in Australia. The Lower Murray-Darling Catchment Management Authority engaged GHD to investigate, design and implement rehabilitation works to restore flood flows and fish passage to approximately 700ha of wetlands.

The team investigated wetland ecosystems to identify environmental values, then used this information to propose works and complementary land management activities aimed at achieving specific rehabilitation objectives for each wetland. The process involved flora, fauna and aquatic assessments, grazing pressure and land management assessments, indigenous cultural heritage assessments, and hydrologic-hydraulic simulation of proposed water regime options.
