Transport infrastructure projects always impact on the water environment. They usually cross several watercourses and often impact on floodplains. Land ownership issues also often restrict the area in which mitigation measures can be achieved.

WHS has significant experience in assessing and reducing the impact of transport infrastructure projects on the water environment and helping transport infrastructure clients get consent from regulators.

Our expertise extends from flood risk assessment, scour/geomorphology and drainage design to ecological and environmental assessments.

We work closely with you. Our scale is our strength, keeping the focus on precise requirements to deliver integrated engineering solutions.

We work closely with regulators. We liaise with regulators during scheme development to ensure that formal consent applications are approved quickly and efficiently.

Our river flow assessment tools lead the industry. The WHS engineers and scientists behind LowFlows and Flood Estimation Handbook (FEH) software have nationally recognised expertise, and are highly regarded by regulators.

WHS work in this sector includes flood, scour, morphological and drainage design for Welsh Government, Highways England, local authorities, Transport Scotland, Network Rail and the Lynton & Barnstaple Railway.
