Robust, applied solutions in sediment and water quality improvements

The Precision Erosion and Sediment Management Research Group (PrESM) is focused on developing cost-effective, timely, and verifiable strategies to precisely define, target, and manage erosion and sediment sources in our waterways and catchments. We use field- and data-driven approaches in geomorphology and geochemistry to understand major sediment sources within our catchments so that we can cost-effectively reduce sediment yields and improve the water quality of downstream aquatic and marine ecosystems, especially the Great Barrier Reef.

Our research has contributed important new insights into how sediment sources are identified and targeted, resulting in a significant shift in government policy and practice. If we are to reduce sediment yields from erosion sources, it is critical that we fully understand the range of drivers and controls on such erosion processes, and that we can precisely identify them.

We apply rigorous, innovative, yet pragmatic solutions to the major geomorphological issues that arise in the management of land and stream degradation. We are developing and trialling a broad suite of precision landscape analysis methods and emerging techniques that can now been combined into approaches in targeted erosion management.

PrESM is a network of scientists and researchers administered through the Coastal and Marine Research Centre (CMRC) at the Griffith University Gold Coast Campus.

The eureka moment that could help save the Reef

Our Expertise

We provide extensive scientific knowledge, combined expertise, and problem-solving to the major erosion, sediment load, and rehabilitation issues that are a part of sustainable and wise land management.

Our core members provide expertise and experience in:

  • Fluvial geomorphology
  • Gully geomorphology
  • Catchment management prioritisation
  • River rehabilitation & gully remediation
  • Soil/fluvial erosion & sediment transport dynamics
  • Soil science & soil geomorphology
  • Field research
  • Geochemistry
  • Sediment tracing
  • Optical Dating
  • Spatial analysis & remote sensing
  • Hydraulic Modelling
  • Water Quality Monitoring

Partnerships

Our group has extensive partnerships with the Queensland Government’s Department of Environment and Science, through the Office for Great Barrier Reef and the Landscape Sciences, Science and Technology Division.  In addition to active collaborations in five of the featured projects, Assoc. Prof Brooks sits on the GBR Sediment Working Group which is a joint Australian and Queensland Government initiative, facilitated through the Office for Great Barrier Reef.

The Australian Government’s Reef Trust investment programme is a major vehicle for investment in Reef Water Quality Programmes in the Great Barrier Catchments.  We provide technical advice to the partners delivering projects on the ground and help to administer the programme with the Australian Government.

We also undertake numerous projects that are funded through NESP (and its predecessors) which are focused on high priority research needs of the Government, and the outcomes of which feed directly into government policy. Assoc. Prof Brooks also sits on the GBR Sediment Working Group which is a joint Australian and Queensland Government initiative.

Natural Resources Management Agencies represent the front line for the implementation of projects funded by government to achieve on-ground environmental outcomes.  Applied research in catchment and water quality management can only work in a collaborative environment where there is a two-way flow of information and ideas between scientists and land managers.

Often the end-users are land holders themselves, and it is these groups that provide the interface and point of first contact with landholders.  For this reason, we work closely with a range of these groups, including;

  • Cape York NRM
  • NQ DryTropics
  • Reef Catchments
  • Terrain

The gully rehabilitation research projects that we are undertaking on Strathalbyn Station in the Burdekin is a continued partnership with Greening Australia and Fruition Environmental (along with the Queensland Government), and this work has recently been extended via a new Reef Credits based project with Greencollar and the landowner, Mr Bristow Hughes.  To date this is the largest gully rehabilitation project undertaken in the GBR.

In addition to developing the Reef Credits gully methods with Greencollar, we are embarking on the first project implementing the Reef Credit gully methods on Strathalbyn Station along with Greening Australia.

Much of the land management research we have undertaken in Cape York is undertaken on Aboriginal owned Land, so working with Traditional owners is fundamental to achieving land management outcomes in this landscape.  We are currently working with Jabalbinna Aboriginal Corp and Western Yalangi Aboriginal Corporation – who together have formed the Yalanji Joint Venture Partnership to undertake work on Springvale Station, in the Normanby Catchment (the property purchased by the Qld Government for its landscape restoration potential and its biodiversity values).  Through this project we aim to train the next generation of gully rehabilitation practitioners, so they can form the backbone of an ongoing industry implementing water quality improvements throughout Cape York and beyond. We also work closely with the Laura Rangers on the Crocodile Station gully rehabilitation projects and the Balnggarrawarra Rangers on Normanby Station.
