The Olympic Sailing Competition 2012 will take place in Weymouth Bay and Portland Harbour, United Kingdom. Following the good experience during a.o. the Olympic Games 2008 in Qingdao, Svašek Hydraulics will again assist the Dutch sailing team during the Olympic Games 2012 by providing specific current focecasts of the sailing area.

In order to validate the by Svašek Hydraulics in-house developed numerical flow model (FINEL2D) of the European Continental Shelf, current data has been obtained by means of a current measuring campaign. Late September 2010, the Svašek team has set off to the UK to perform the current measurements.

The measurements have been performed with a vessel mounted AWAC. Both the flow velocity and flow direction over the full water depth have been measured during five 13-hour measuring campaigns. During these campaigns, the current has been measured along three different transects and during both spring and neap tide.

Since the current measurements have been performed in areas with a depth of 15-20 m, the influence of the wind on the measurements has been limited, by which the obtained data has proven very useful to the model validation. By now the FINEL2D flow model had been successfully validated. The model has also been used to provide current forecasts for the Olympic Test Event of 2011 in Weymouth.

The forecasts have assisted the Dutch team to win two gold, one silver and two bronze medals during this event.
