Vortex (whirlpool) in flood waters Inskip Point - Beach Disappears 2 months ago   00:24

A vortex (whirlpool) in flood waters of the Olway Valley, near Usk, Monmouthshire, on 25th November 2012. The vortex is created on the upstream side of an archway under a road causeway across the floodplain of the Olway Brook. The flood level is higher than the top of the arch. Note that the vortex is stationary and if deep enough might erode the floodplain surface beneath, especially if armed with pebbles and other debris. A still photograph of the vortex is available at http://www.flickr.com/photos/profsimonhaslett/8220247826/

Inskip Point - Beach Disappears Vortex (whirlpool) in flood waters 2 months ago   02:27

This film was recorded in 2005, moments earlier they were a number of 4X4 parked in this section of beach with guys fishing near by.
These sink holes appear every now and again along Inskip Beach near where the ferrys cross between Inskip Point and Frazer Island, They are caused by whirlpools that are generated in the deep passage every few years. The whirlpools sometimes make it shore and undermining the beach. Eventually the weight of the sand becomes to great to support itself and it collapses in a matter of minutes and has the potential to take with it anyone standing there.
