They can, and no doubt will. But they'll have to wait until the risk of further flooding goes away and that waterlogged ground dries out sufficiently for them to be constructed safely. They'll also have to be brought to the sites from god knows where they're stored. Sod's Law says there won't be any for 100's of miles.

Because if stone bridges trhat have withstood the forces of nature for hundreds of years are collapsing under the pressure of water, perhaps a bridge based on floating on the same water just might not be up to the task?

A Pontoon bridge is a floating bridge, not a good idea in the circumstances, what is needed is a Bailey bridge, which is constructed in a lattice design.
This excerpt was taken from the history of Shardlow in Derbyshire.
//// In 1761 the Cavendish Bridge was opened as a toll bridge. In 1947 it washed away and the army provided a temporary Bailey Bridge, which was replaced by the present structure in 1957.////
So it was in use foe 10 years, that's not bad.

AOG you may be right about Bailey bridges and I assume the Army are able to construct both and decide on the best method and have excellent experience in the field. I notice that civilian companies have now got into the act and offered to build temporary bridges but I would think the Army could carry out the operation quicker.
The confirmation by modeller, the ex Army RE gives some comfort as to their suitability considering the width of some rivers not to mention the river flow.
I suppose its all down to cost and of course with the Army involved the taxpayer is only paying for materials to do the job.

whereas the 2 key road bridges in workington are out of use effectively cutting the town in two, the rail bridge still stands, and the trains are running normally.
is it beyond the wit of authority to ask network rail to provide a temporary platform at northside, and northern rail to stop their trains at it?
