The Department of Energy, Environment and Climate Action (DEECA), in collaboration with Victoria’s Catchment Management Authorities (CMAs) and expert consultants, has recently published the updated Technical Guidelines for Waterway Management, a significant resource for professionals working across the state’s waterways.
A Fresh Approach to Waterway Management
These updated guidelines, released in 2024, represent the most comprehensive revision since their original publication in 2007. Reflecting nearly two decades of scientific research and practical insight, they provide a modern, evidence-based framework for managing geomorphic processes in rivers and streams throughout Victoria.
At the heart of these guidelines is a commitment to supporting resilient, ecologically healthy, and culturally valued waterways — recognising that rivers are dynamic systems rather than static features of the landscape.
A Four-Step Decision-Making Framework
To guide effective waterway interventions, the guidelines outline a structured, four-step decision-making process:
- Understand Site Values and Processes
Begin by assessing the physical, ecological, cultural, and social values of the waterway, along with the key geomorphic processes at play. - Decide Whether to Intervene
Carefully consider if and when intervention is necessary, recognising that allowing natural processes to continue may sometimes be the best option. - Develop a Reach-Scale Management Strategy
Create a holistic plan that addresses the entire reach of the waterway, ensuring consistency and long-term effectiveness of any works undertaken. - Design and Implement Context-Sensitive Works
Plan and execute solutions tailored to the unique conditions of the site, using best-practice techniques that promote waterway health, stability, and biodiversity.
Addressing Key Geomorphic Challenges
The guidelines offer practical guidance on managing common geomorphic challenges, including:
- Incision — Deepening of riverbeds that can destabilise banks and threaten nearby infrastructure.
- Aggradation — Sediment build-up that alters flow patterns and habitat quality.
- Meander Migration — Natural shifting of river bends over time, which can affect land use and infrastructure.
- Avulsion — Sudden shifts in a river’s course that can dramatically alter landscapes.
Importantly, these challenges are not viewed as problems to be ‘fixed’ in the traditional sense but as natural processes to be managed in ways that enhance waterway resilience and functionality.
Promoting Resilient, Living Waterways
Rather than aiming for rigid, unchanging river forms, the guidelines embrace the dynamic nature of waterways. They highlight the importance of allowing rivers to adjust and evolve while ensuring that interventions support ecological integrity, protect infrastructure, and respect cultural values.
Native vegetation plays a central role in this approach, recognised for its contribution to bank stability, sediment trapping, habitat provision, and overall waterway health.
Tools and Resources for Waterway Managers
Designed for a wide audience — including waterway managers, consultants, Traditional Owners, and community stakeholders — the guidelines include:
- Standard drawings and design examples
- Worked case studies
- Checklists and practical tools to support transparent, informed, and adaptive decision-making
These resources ensure that all involved parties can contribute to sustainable waterway management outcomes.
A Valuable Resource for the Industry
At DPM Consulting Group, these guidelines are particularly relevant to our Water Resources and Civil Engineering teams, who routinely consider geomorphic processes in projects ranging from stormwater management to flood risk mitigation.
Their emphasis on adaptive, context-sensitive design aligns closely with our commitment to delivering sustainable, practical, and forward-thinking solutions for clients across Victoria.
