RNLI rescue crews pulled a man from the River Thames on Wednesday evening after he was spotted clinging to a rubbish barge.
The recent flooding has caused an unprecedented number of sinkholes to appear in roads and near people's homes. Martin Stew investigates.
The 600-metre aqua-dam was pumped full of flood water on Friday to protect 200 homes.
The rivalry between Cambridge University and Oxford University continues with the annual boat race on the River Thames this afternoon. Cambridge is desperate to deny Oxford its fifth Boat Race victory in seven years.
Since the races began back in 1829, Cambridge has won 81 times, while Oxford's victory tally stands at 77 races.
Deputy Mayor of London for transport Isabel Dedring said:
The Mayor (Boris Johnson) has long championed greater use of the river for both passenger and freight travel.
With record numbers of passengers now travelling on the River Thames, it is fantastic that freight on the river is also... contributing to a reduction in congestion on our roads.
James Trimmer, from the Port of London Authority, said:
Last year the Thames carried over 265,000 lorry loads of materials. That's a quarter of a million lorry journeys saved. It's good for the environment and communities, with less pollution and noise.
The amount of freight moved through London on the River Thames has trebled over the last four years.
The Port of London Authority says that 5.3 million tonnes was moved in 2013 - a 62% rise on the 2012 figure.
The majority of the increase was down to an extra 1.8 million tonnes of spoil being transported from construction projects, particularly the cross-London Crossrail scheme.
A body found in the Thames this week has been formally identified as that of Marc Hutton, who went missing from Putney on 28th February.
His body was found in the river near Lots Road in Chelsea on Tuesday.
The Metropolitan Police are treating his death as unexplained. An inquest date is yet to be confirmed.

"This incident has been recorded as a life saved as there were no other boats in the area at the time and I don’t think anyone was actually aware he was in the water.
He was incredibly fortunate in that respect.
We still don’t know how he came to be in the water but due to an unusual twist of fate we managed to avoid one more fatality on the River Thames last night.
That first person who was threatening to jump from London Bridge probably has no idea that, all things considered, he saved another man’s life."
A man threatening to throw himself into the Thames inadvertently saved the life of a stranger who was drowning in the river below.
Tower RNLI crew say they would never have spotted a person in the water if it wasn't for the callout to reports of someone on a ledge and ready to jump at London Bridge late on Wednesday evening.
By the time they arrived police had managed to talk the man down, but the crew spotted someone else on the bridge pointing towards the water.
It was then that they spotted the person in the river, desperately struggling to keep his head above the water as he was dragged down by a large duffel coat.
When they pulled him out, the crew found he was suffering from hypothermia and he was taken to hospital.
The RNLI say they don't know how the person ended up in the water, but he was said to have been alert and apologetic when he was attended to by crews.
The London Boat Race is now only weeks away and crews are to be officially unveiled later this morning.
Weigh ins will also take place in front of the waiting media in Central London.
