Reclaim the Beach
Sun | 2 to 7pm | Foreshore by Festival Pier
Beach party featuring live music, comedy, sandcastles, Punch and Judy and more - including the utterly unique Ken Campbell.
Does this mean there are plans to raise the Thames Barrier again this year between low tides, so that we get the beach for the whole day? [If I'm reading the tide tables rightly, natural low tide is at 10.47 in the morning, and there would be 6 more metres of water expected by late afternoon!]
Is there any risk that it may have to be abandoned following Thames Water's pollution during the recent downpours?
I hope so! They're certainly in the advance publicity...
Sun | 7.30pm | Victoria Embankment to Upper Ground
Over 2,000 people take to the streets for this must see spectacle. Themed to Wild Things, there are musicians, dancers and performers with amazing lanterns, illuminated costumes and fantastic floats. Highlights include massive insect and underwater lanterns by Catalan group Sarruga, awesome costumes by Shademakers, street show by Art Start, structures by Emergency Exit Arts, dance by UrbanConnectShine, a thirty foot Birdcage by Lumina and carnival excess by Paraiso.
Please note: the Night Carnival is best seen on Victoria Embankment and Blackfriars Bridge.
Groupe F Fireworks
Sun | 10pm | Thames by Gabriel's Wharf
A mid-river display by the world's greatest pyrotechnicians hard on the heels of their stunning shows for the Athens ' Olympics.
It sounds more like the sort of maths problem I could never get to grips with -
Presumably you would first need to estimate the surface area of the Thames between Teddington Weir and the Thames Barrier. I think geograpgers have some rough and ready calculus for this if you know the river's width at both points and the distance in a straight line on the map.
You then need the volume of water entering per unit of time,
>"The freshwater flow over Teddington Weir is normally maintained at about 800 million litres/day (178 million gallons/day) but it can be as low as 200 million litres/day (44 million gallons/day) in times of drought. Conversely, it may exceed 30,000 million litres/day (6600 million gallons/day) during the winter. The mean flow (taken over 25 years) is about 5200 million litres/day (1145 million gallons/day)."
So you would need to make some assumptions on likely weather...
Also, are you allowed to assume that the slope of the banks doesn't need to be taken into account.
