Defending the coast from flooding is a challenging job, especially with the uncertainty of climate change and rising sea level.
To improve coastal flood hazard forecasts and how our coastal schemes are designed, we need to be able to observe the sea as it crashes against sea walls.
A new prototype instrument to measure the volume and speed of waves as they spray, shoot and slop over a sea wall has been engineered at the National Oceanography Centre in collaboration with HR Wallingford. The specialist information from this system and computer modelling has allowed Jenny and her team to understand hazardous wave events at a local study site near Liverpool to improve flood forecasting.

Following on from this project the new system has been deployed in Dawlish and Penzance, in collaboration with the University of Plymouth, to assess its performance in higher energy wave conditions. At the same time measurements of the beach level were collected to understand the influence of the beach on wave overtopping hazard.
Dr Jenny Brown from the National Oceanography Centre joins us to present this subject.
