The Thames Barrier prevents the floodplain of most of Greater London from being flooded by exceptionally high tides and storm surges moving up from the North Sea. It has been operational since 1982. When needed, it is closed (raised) during high tide; at low tide it can be opened to restore the river's flow towards the sea. Built approximately 3 km (1.9 mi) due east of the Isle of Dogs, its northern bank is in Silvertown in the London Borough of Newham and its southern bank is in the New Charlton area of the Royal Borough of Greenwich.
Built across a 520-metre (570 yd) wide stretch of the river, the barrier divides the river into four 61-metre (200 ft) and two approximately 30-metre (100 ft) navigable spans. There are also four smaller non-navigable channels between nine concrete piers and two abutments. The flood gates across the openings are circular segments in cross section, and they operate by rotating, raised to allow "underspill" to allow operators to control upstream levels and a complete 180 degree rotation for maintenance. All the gates are hollow and made of steel up to 40 millimetres (1.6 in) thick. The gates are filled with water when submerged and empty as they emerge from the river. The four large central gates are 20.1 metres (66 ft) high and weigh 3,700 tonnes each.[6] Four radial gates by the river banks, also about 30 metres (100 ft) wide, can be lowered. These gate openings, unlike the main six, are non-navigable. (Wik)

Some more impressions form the Lake Garda / Italy.

Too high, too far, too rocky, too tired, not enough time. Some places you really want to go seem so unreachable, even when you're so close.

Long exposure shot of Thames barriers. I personally prefer high tide. Normally I check it online before going out but not this time:-).

I quite liked the red white and blue colours in this shot.
Barrier Lake is a man made reservoir at the north end of Kananaskis Country in Alberta, Canada.. Trapped methane causes frozen bubbles to form under the ice on the lake's surface. This phenomenon results when decaying plants on the lake bed release methane gas, which creates bubbles that become trapped within the ice, in suspended animation, just below the surface as the lake begins to freeze. The visual effects formed by the resulting stacks of bubbles, frozen while rising toward the surface, combined with the clear blue water, have made Abraham Lake a popular destination for photographers and nature observers.
The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres over an area of approximately 344,400 square kilometres. The reef is located in the Coral Sea, off the coast of Queensland, Australia.

I never envisioned this image. It came to a life (or death) of its own when I began experimenting with filters and blending options in Photoshop. This image was taken inside a shopping mall in Calgary, Canada, and became something futuristic and cataclysmic.
