Hydraulics for aquatic ecology

The Fourth Element team has extensive knowledge of aquatic systems in wetlands, rivers and estuaries. We have deployed this knowledge in the planning and design of river and wetland rehabilitation and the development of Green Infrastructure solutions in the urban and mining environments.

We combine scientific knowledge with eco-hydraulics and we now apply 2-D hydraulic models to map and analyse in-stream habitat in river, wetland and estuary environments.  Combined with this, we undertake surveys and biomonitoring according to SASS5 requirements. We work with specialist ichthyologists and amphibian specialists.

We are capable of providing ecological flow requirements for lotic systems using a range of methods. This enables us to provide reserve determinations from desktop to comprehensive level.
