Applications and impact

River Styles has had international impact on river management through application of the Framework. The following are a selection of applications that demonstrate the potential for River Styles to integrate with other management tools and provide a geomorphic basis for river management.










International applications

European REFORM project and Morphological Quality Index (MQI)

Restoring river ecosystems in Europe: the REFORM project’s objectives were to provide tools to support cost-effective implementation of restoration measures and monitoring to reach the ecological objectives for rivers as required by the EU Water Framework Directive. REFORM aimed to improve existing tools and develop new ones to increase the success and cost-effectiveness of restoration measures and procedures to monitor the biological responses to hydromorphological changes with greater precision and sensitivity. For this, REFORM developed an open-ended hydromorphology framework incorporating multi-scale spatial and temporal aspects that builds heavily on the River Styles Framework. It aids users in developing understanding of the morphology and dynamics of river reaches and their causes. The Morphological Quality Index (MQI) is the method recommended by REFORM for assessing river condition. The MQI builds directly on Stage 2 of the River Styles Framework. The method is extremely useful for analysing and interpreting critical problems and causes of alteration.

United Kingdom: Climate change impacts on river typologies for the Water Framework Directive – Environment Agency, UK

The Environment Agency reviewed the usefulness of incorporating hydrological, geomorphological and ecological attributes into a typology of rivers as a basis to assess the impacts of climate change on the physical structure and condition of rivers. In this review it noted that because of its process- and trajectory-based approach to analysis that River Styles Framework “has great potential for river management and has been used for problem-solving, application and participatory management” when assessing potential climate change impacts on rivers.

USA: Columbia Habitat Monitoring Program (CHaMP)

The goal of CHaMP is to generate and implement a standard set of fish habitat monitoring (status and trend) methods in up to 26 watersheds across the Columbia River basin. The program undertakes larger salmonid population-level life cycle modelling and restoration activities and uses this to priortize habitat for salmonids listed in the Endangered Species Act. The application has been in the Interior Columbia River Basin in the Pacific Northwest. The River Styles Framework is used as the geomorphic template for identifying river types and associated geomorphic structure, to assess geomorphic condition and recovery potential. The Framework has also provided a basis for integrating a range of geospatial tools, and generating new tools for assessing the ecohydrology and geomorphology of rivers more generally.

USA: River Styles Report for Middle Fork John Day Watershed, Oregon

As part of CHaMP (see above), the Middle Fork John Day Watershed was chosen as an exemplar demonstration catchment for which a full River Styles assessment was undertaken and used as a basis for developing a range of automated toolkits for analysis of River Styles. The initial report also undertook a full analysis of geomorphic condition, recovery potential, and management prioritisation. The mapping outputs are instrumental for communicating with key stakeholders.

USA: Texas Water Development Board

The River Styles Framework has been used in Texas (USA) as a geomorphic classification tool to characterise the rivers of the Gulf Coastal Plain. It was chosen as the appropriate tool as it is “specifically intended to incorporate evolutionary pathways of the fluvial system, rather than static conditions that are presumed to be related to stable equilibrium states”.

NSW Department of Industry (DoI)

NSW DoI (formerly DPI) has applied the River Styles Framework in mapping and assessing river types, river condition and recovery potential across the state of NSW since about 2000. Analyses of geomorphic condition are incorporated with other indices of hydrological stress, threatened species and vegetation condition to create the River Condition Index. State-wide overage of River Styles (all 4 stages) is soon to be available.

This significant investment has been used by many departments, including NSW Local Land Services, DoI Fisheries, DoI Water and former Catchment Management Authorities to achieve savings through improved decision making and prioritisation of activities. The state wide assessment also provides a database to that illustrates the range of River Styles, reference reaches for practitioners to consult, and target conditions to guide management and rehabilitation approaches. The Framework is also used to inform Water Sharing Plans across NSW.

NSW Catchment Management Authorities (fmr) – Catchment Action Plans

Catchment Action Plans (CAP) provides the strategic direction of natural resource management to ensure better outcomes for native vegetation, biodiversity, land, rivers and coastal waterways. This is achieved through a range of targets that each Catchment Management Authority (CMA) developed in consultation with farmers, local groups, Aboriginal communities, local governments, industry, and other NSW and Commonwealth agencies. The River Styles Framework was utilised in prioritising reach-scale management and rehabilitation in CAPs for the Central West CMA, Lachlan CMA, Hawksbury-Nepean CMA, Hunter-Central Rivers CMA, Namoi CMA, Northern Rivers CMA, Murray CMA and Sydney Metropolitan CMA.

NSW Catchment Management Authorities (fmr) – River Health Strategies

NSW River Health Strategies used River Styles to assessing river reach structure and function, geomorphic condition, recovery potential and threats to recovery. This was used in conjunction with indicators of ecological health to set a strategy to:

  1. Maintain the condition of river reaches where they are in natural or near natural condition
  2. Maintain and improve river reaches where they are in good condition
  3. Improve the environmental condition of the remaining river reaches
  4. Achieve the highest environmental and community gain for the resources invested


NSW Natural Resources Commission – Monitoring, Evaluation and Reporting Strategy (MER)

The MER Strategy supports regional delivery of Natural Resource Management (NRM) in NSW and informs the review, revision and ongoing implementation of Catchment Action Plans and other high-level strategic plans such as the NSW Biodiversity Strategy. The aim of NRM MER is for a seamless link between local, regional, State and Australian Government NRM data that truly informs and guides the whole community on how we care for the natural resources of the State and builds robust mechanisms that facilitate the acquisition, management and sharing of NRM data. The River Styles Framework is used as one of the key baseline datasets used in this strategy.


NSW Local Land Services – Transition Catchment Action Plans and State Strategic Plans

River Styles, as part of the NSW River Condition Index, is incorporated into the long term strategic catchment planning of the NSW Local Land Services (LLS). Prior to the transition to LLS, the Catchment Management Authorities (CMA) used the River Styles Framework as a key dataset in their River Health Strategies and Catchment Action Plans. This work is ongoing as part of a strategic goal for healthy, diverse and connected natural environments in the LLS State Strategic Plan.


NSW State of the Environment Reporting 2012 and 2015

NSW State of the Environment (SoE) reports on the status of key environmental issues facing New South Wales. The River Styles Framework was used to create a Statewide assessment of geomorphic condition, providing a more detailed analysis than previous work including the Murray-Darling Basin Sustainable Rivers Audit.

NSW Department of Primary Industry (Fisheries) – Fish communities and threatened species assessment

The NSW River Styles geodatabase is used to model the potential distribution of threatened species of fish. The nested hierarchy of criteria based on valley setting, channel planform, geomorphic units, and bed material allowed the incorporation of geomorphic information in the analysis. The dataset is used to spatially represent the status of fish communities at river reach scale across NSW and provide support to strategic planning frameworks to ensure they effectively integrate biodiversity considerations into planning and decision making processes. The River Styles Framework has also been used to select potential new stocking sites for fish rehabilitation programs.

QLD – Mary River and Tributaries Rehabilitation Plan 2000

“The plan prioritises strategies based on the ‘Titanic’ philosophy which argues that protection of natural assets (keeping good ships afloat) is more cost effective than rehabilitating highlydegraded reaches (raising the Titanic). Reaches of relatively homogeneous character and behaviour are classified along the lines of the River Styles approach. Assets, problems and the recovery trajectory are identified, before each reach is categorised into a seven tier hierarchy. Categories range from protecting and restoring reaches of regional conservation significance through to stabilising highly degraded sites with little chance of natural recovery. The plan sets out a 50 year vision, and ten yeargoals. These aim to reverse current trends by motivating and empowering the community to adopt river rehabilitation techniques that are based on a solid understanding of riverprocesses.”

Landscape-scale assessment of watercourses in remote arid South Australia to inform mine planning and mine closure – Iluka Resources and Alluvium Consulting

The River Styles Framework was used to characterise complex arid zone catchments, and in conjunction with modelling provided guidance on pre-mining operations and infrastructure placement. It is also used to guide post-mining rehabilitation of complex watercourses. The flexible nature of the River Styles Framework allowed its use in a complex arid-zone system where the study identified previously unrecorded river types with unique character and behaviour.
