Fourteen severe flood warnings have been issued along the River Thames in Berkshire and Surrey, amid concern that people and property are at risk.
In the village of Datchet, members of the military have been building up defences to try to divert water and protect homes.
"We're here to build a 2ft-high sandbag wall about 600m in length to redirect the flow of the river", Lt Cdr Paul Barker told the BBC's Ben Ando.
