You each have been given a location on the UK coastline {My location for the coursework is 37}
you will then have to carry out a refraction,
shoaling and breaking analysis to determine the wave conditions at the toe of your coastal defence
structure. The assumptions for these calculations are as follows:
The depth of water at the toe of your structure is 3m.
Assume the structure is a 1 in 3 sloping revetment protected by rock.
The beach slope immediately in front of your structure has a 1 in 10 slope (1 vertical to 10
horizontal).
Assume that wave heights are limited to a maximum of 60% of the depth of the water at the
structure toe.
Determine the wave period assuming that the wave steepness in deep water is equal to 0.04 where
steepness is given by equation (1).
Assume that the crest of the structure is 2m above the water level.
