Photographer's Note

Another one photo from a famous view of my city Chalkis: the old bridge.

Some important infos:

Chalkis is built on the narrowest sea passage which separates the island of Evia from the mainland of Greece. The passage is called Evripos. In ancient Greek the term evripos meant straight (channel). In the 19th century the bridge shown in the picture above was built on Evripos. This bridge was destroyed at the end of that century during the widening of the channel.

Strong tides occur in the channel and also the rare tidal phenomenon of the sea water flowing like in a river for 6 hours towards one direction and for the same amount of time towards the opposite direction with a pause of about 9-10min. The velocity of water is 7-9 Km/hour. This happens for 23-24 days per month while the rest 5-6 days the direction of the flow and the velocity of water are irregular and they do not obey any rule. This remains under investigation.
