Flood Engineering Services

Flood advice that informs planning, design, approvals, and long-term resilience

What we do

Understanding flood behaviour early, is critical to ensuring that project constraints inform the design. Reeca assesses catchments, waterways, drainage networks and overland flow, including hazard, access, climate change and mitigation. We test what the findings mean for feasibility, levels, layout, storage, conveyance and civil design, then connect them to planning and engineering requirements. This gives clients a defensible basis for approvals, infrastructure design and long-term flood resilience.
