Fast-Flowing River Corrib

The River Corrib can be amazingly fast-flowing as it passes through Galway City to join the sea. The pictures above try to capture the ever changing rough texture of the water surface; while the video clips below give you a more immediate experience of the rush and the noise of the water.

Bishopston Pill at Pwll Du Beach

Video

This short video clip shows two streams of water gushing from the base of the large multi-tiered shingle bank that blocks the valley at Pwll Du Bay in Gower, South Wales. The water comes from the Bishopston Pill river that flows down the valley to the shore, but which has been dammed up behind the shingle. In summer, reduced water flow means that just a trickle seeps out of the shingle base and spreads across the shore. This video was taken in October after heavy rain had increased the quantity of water in the river and subsequently the pressure of the small lake behind the pebble bank. There is a fast and steady flow and the two streams have begun to create channels through the pebbles before converging on the beach. Apparently, in winter, the build-up of water pressure behind the bank means that the river cuts its way straight through to the sea.

The wind blowing sand along Rhossili Beach

Gale force wind driving sand grains across the beach at Rhossili on the Gower Peninsula, eroding the seaward-facing edge of the marram-covered dunes, and accumulating as new sand drifts (December 2013).

Sea Foam and High Winds at Rhossili

Natural patterns of sea foam driven by high winds at Rhossili

It was so windy on one particular day at Rhossili that a layer of surface water was retained on the beach even when the tide had receded. Sea foam was whipped up and driven at high speed across the surface film, making natural scalloped patterns as it travelled landwards. The wind was incredibly noisy and so strong that it was difficult to stand upright and keep the camera level – but I wanted to catch the exhilarating moment.

Waves from more than one direction

In answer to a comment I received yesterday about the sand ripple pattern photographs I posted, I do think that sometimes the complex sand ripple patterns on the beach are created when the water coming ashore hits the beach or recedes from the shore in different directions, at varying angles. These videos show very shallow water waves gently breaking on the sand in that way, and then ebbing, flowing over the sand ripples they are shaping, on the beach at Rhossili in the Gower Peninsula of South Wales.
