Query: A Study of Energy Transfer of Wind and Ocean Waves   To develop a better understanding of energy transfer between wind and
different types of waves a model was created to determine growth factors and
energy transfers on breaking waves and the resulting velocity vectors. This
model was used to build on the research of Sajjadi et al. (1996) on the growth
of waves by sheared flow and takes models of wave velocities developed by Weber
and Melsom (1993) and end energy transfer by Sajjadi, Hunt and Drullion (2014).
