Healthy rivers are at the heart of economic success, contributing to water supply, tourism, agriculture, transport and power generation.

We understand the complex natural systems and sensitivities of rivers, ensuring habitats and ecosystem functions are sustained and restored.

River health is degraded by pollution, urbanisation, industrial processes, and worsened by climate change. Arup’s water team addresses river health through catchment management, reach-scale restoration, and targeted interventions, based on the latest scientific and engineering insights. 

Our services combine technical solutions with wider environmental commitments and goals. Our capabilities include catchment management, river restoration, geomorphology, water quality, river health, and natural flood management.
