Assuming you're plotting VOF = 0.5 surface and the height on that it'll tell you the free surface height. You'll need to work out which are the incoming and refracted waves.

we are having doubts in knowing incoming and refracted waves . How do we understand it from the graph?
This image shows the wave height plot and from this how do we know about the refracted wave? or is there any other method to find its height?

I'd look at the contour plot and look at height and velocity in adjacent plots: hopefully the reflected wave is moving away from the sea wall. I'd also look into why you have the odd loop in the plot at around x=9.

In the graph we have plotted for length (x) and height (y) ,is it incorrect?? Should we create a contour plot for velocity and length ?? and the odd loop is because of boundary conditions ??How can we resolve it??
How to get proper wave elevations?

Have a search for "depth" in the Fluids section on here, I've answered the water depth question before. Nothing wrong with plotting positon and height, but you also need to find which direction waves are moving. Images (and movies) are very useful to see what's going on.
