Great aerial shot Ian. Greetings Berend

Greetings Berend,

I was thinking of my former geography classrooms when I made this photograph.

With a view like this, it is easy to explain to people how the surf interacts with the beach. The relationships between beach and foredune are also portrayed in this vertical view.

Here one sees that the wave breaks on the beach at its southern end first, and in so doing creates a movement of water in the surf-zone that is northward along the beach. This determines sand movements and shapes the coastline.

As coastal engineering and management are so crucial in NL, I am sure you must be the most coast conscious nation on the planet.

Regards,

Ian

Yes, it correspond to the map besides! ;-)
Wonderful shot!

Thanks for the affirmation, Polytropos, especially the geo-correspondence ;-).

Actually for aerials, I have decided that we need to change the convention used in Panoramio for aerials, particularly for oblique aerials. It is far better to geolocate the centre point of the photo then the vertical camera position. That is what I have done with this image, but then because it is quite a high-angle photo that doesn't make a whole lot of difference, in this case.

In comparing the 2 images, this and the map image, did you notice that the strong rip and gutter that appear in the map image have almost gone? The rebuilding of the beach by swash has created a sandbank in the position of the earlier gutter. The dynamics of sand beaches and their surfzone are rapidly changing processes.

Greetings from Australia,

Ian
