Summary on Grant Application Form
This project proposal is to undertake a physical model study in the CRF to complement the EPSRC funded Elmer Breakwater study, currently nearing completion. This will enable the direct comparison of physical model results and computational model results with a unique set of comprehensive and high quality field data. A model scale of 1 to 25 is proposed. This will enable one complete beach cell, between tow breakwaters to be modeled together with tow further breakwaters, one on either side, to minimise boundary problems. In the first stage a fixed bed will be used followed by a mobile bed in the second stage. Two possible model sediments will also be considered, anthracite and coarse sand. Model measurements will include directional wave spectra at a variety of positions, current measurements and beach topography. Directional random sea states and tidal levels, as defined from field measurements of particular events, will be simulated. Various model runs will be undertaken specifically to evaluate the effectiveness of computational models and the physical model from field data, investigate sediment scale effects (possibly comparing the response of and and anthracite) and investigate forms of offshore breakwaters which will simultaneously provide coastline control without producing downcoast erosion. It is envisaged that this will take the form of submerged breakwaters with the evolution of salients as opposed to tombolos. Finally, it is intended to carry out some tests to investigate the generation of long period motions and their effect on beach formation/evolution.
