SenSat | Leeds Flood Alleviation Scheme Case Study


Faster and safer:

Solutions that curtail emerging flood risks



BAM Nuttall - one of the UK's  largest construction and

engineering companies  - called upon SenSat to replicate a 12km flood corridor in Leeds. The resulting digital simulations helped them better understand flood risks and design engineering mitigations.

Flood risk is on the increase in the UK. On 26 December 2015, Leeds experienced significant and widespread flooding from some of the highest river levels ever recorded. In the second phase of alleviation works, the River Aire catchment area is being considered to reduce flood risk in Leeds, including areas such as Kirkstall and Stourton. Accurate topography and surface mapping are crucial to understanding flooding better. For this SenSat, was called in to survey a large flood corridor.

The Project


Designing flood defence structures and systems can be challenging, especially when the available survey data on the existing waterfront is outdated and incomplete. The design team needed to validate their designs against the realities of the 12km complex urban/river interface ground space, where the contracting team would work. 

This assessment covers some areas including working spaces, safety, design constructability, environmental impact, and several other important engineering processes.
