Have you checked your text or online?
yes - i can't find a specific definition
Hmm. Look what I found for the first term.

http://www.google.com/#q=beach+morphology+definition
i don't understand the meaning
"Beach morphodynamics (i.e. the dynamics of beach morphology) refers to the study of the interaction and adjustment of the seafloor topography and fluid hydrodynamic processes, seafloor morphologies and sequences of change dynamics involving the motion of sediment."

Look up the words you don't know.
some great help you are!
