Summary on Grant Application Form
This proposal is for continuation of work which is being pursued in the Breaking Wave Impacts on Steep Fronted Coastal Structures project. Measurements have been made of the impacts of waves from the Atlantic Ocean on a breakwater at Alderney, and of waves in large-scale laboratory facilities in the Large Wave Channel at Hanover. In addition mathematical models are developed to describe the waves' transformation as they approach a breakwater and for the dynamics of an air-water mixture as waves impact on a wall. The aim of this part of the project is to gain sufficient theoretical understanding of the impact process so that guidance can be given on how to scale results from the laboratory to prototype. Central to this scaling is the air that is trapped by waves breaking onto a wall and the entrained air that is mixed with the water, which creates a very compressible fluid.Continuation funding is sought since:1) wave and weather conditions have given us very few violent impacts on the breakwater, further measurements are to be made.2) an excellent and substantial data set from the GWK has given surprises, such a wide range of different impact conditions, and pressures higher than previously measured in this context, so that more time is needed on the project to assess them in theoretical models and for comparable experiments at a smaller, more usual, scale to be performed.
