The river flowing down to the seashore meets with waves from the sea at Charmouth in Dorset, England. This somewhat abstract image of the natural patterns generated from the meeting of the two forces shows the freshwater continuing to flow smoothly seawards on the left of the channel (top left) while on the right it rebounds from the curving bank with the ripples moving upstream and towards the middle of the channel. The blue and white are reflected sky, and the yellow is reflection from the shingle beach.
The further you walk along Weymouth pier the deeper and bluer the water – turquoise tinted. In the shallows, the sand on the sea bed makes the water appear more yellow. On this calm day, the water surface was riffled by the wind to produce patterned textures where the transient ridges were delineated by the light they caught.
These images are a study of patterns and surface texture on the shallow water over the sandy seabed at Weymouth, viewed from the promenade leading to the pier. I like the way that the waves look as if they are drawn with fine lines onto the sea with a white pencil. The clear water reveals the yellow of the sand below the waves.

The cliffs are eroding in many places along the Dorset coast, particularly where the rocks are soft. This results in land slips and mud slides. It has always been going on but in recent years the erosional processes seem to have accelerated along with changing weather conditions. At Seatown on the coast near Chideock in Dorset, large boulders have been imported to protect the shore from the sea adjacent to the Anchor Inn that sits at the mouth of the River Char. I cannot name the rock types represented in the rip-rap for certain since they are not local to the area and have been chosen specifically because they are harder and more resistant than the cliffs on this beach. I am not even sure that they were quarried in Britain. However, some of them remind me a lot of Carboniferous limestone with fossils, calcite and haematite inclusions. Anyway, they are really interesting and well worth a closer look. The patterns, colours, and textures are amazing. I would like to visit again when the rocks are wet and the more subtle colour variations would be highlighted.
The bright sunshine created wonderful effects on the rapidly moving, crystal clear water of a chalk stream as it flowed over rounded pebbles. Light reflected from the rippled surface of the water. The stones below were covered with some sort of brownish algae that disturbed the flow and made either rainbow-coloured prisms or golden patterns of reflection.

It is cold today. I wanted to think of a time and place where it was much warmer. I thought back to the holiday I spent in Queensland, Australia, several years ago. It is a wet tropical region and the vegetation is luxurious in the Daintree Rainforest. We did explore the wild as best we could but there was nothing to beat visits to Cairns Botanic Gardens where we could enjoy the wonderful plants without so many of the attendant dangers. Here is a gallery of some of the amazing and beautiful natural plant patterns, colours and textures that I photographed among the vegetation in these fabulous gardens.
