If you live on a flood plain-

Its also more about decent sized rivers, that aint been dredged since the Thatcher years, All governments since have conveniently ignored.

Flooding also has a lot to do with how much water the ground can absorb too.
Diverting water doesn't always work either. Rivers and ditches need to be dredged regularly to make sure that the flow of water is not slowed down.

The Jubilee River was dug out at a cost of £110million pounds in 2002 with a view to preventing the flooding of towns like Maidenhead and Wraysbury, it hasn't worked and those areas have been flooded a number of times in the last 12 years.
Some of the street drains will also be at fault because they will drain directly into the Thames, so that when the river is in flood the water from the Thames will go up the drains and flood the streets.

Wow did you actually find a good thing that Thatcher did?
You better sit down and have a rest

Won't those streets have to be below the level of the Thames for that to happen so likely to flood anyway?

Maybe not. Near where I once lived there was a 'storm drain' which emptied into a local river estuary at below the level of the high tide. The drain was fitted with a one way valve to prevent the river feeding into the drain and also a large underground storage tank for water that could not be discharged when the tide was in. When this system was overloaded it used to blow off a manhole cover and produce a fountain which could be as much as six feet high. All this in the middle of an important road which would then flood and then have to be closed.

Apparently not Neil.
If the drains cannot sdischarge into the river the water has nowhere to go...and when the river is in flood(as it is now) the water goes up the flood drains.

Originally called "global warming" then they realised it wasn't actually getting that much warmer so it changed to "climate change",either way it's our fault and we've gotta pay,Personally I prefer the term nature

Not sure how much cameron gave/is giving of public money to help a (private) train company but It wouldn't surprise me if he had shares in it an that's how he's shifting public money into private pockets (again).Surely they've made enough from tickets over the years to sort they're own crap out? That money could be better spent,maybe on the folk that have had they're lives turned upside down

The Environment agency should use Cameron (and the other MPs) as sandbags,least that way they'd be doing something constructive.

That makes sense, the water in the river is high so it keeps the one way valve closed. Water flowing down hill into the underground storage tank then has nowhere to go so comes out of manholes. The cause is the drains being below the river level

So do I. Not completely convinced by the climate change/global warming thing. The climate has constantly changed since the planet was formed.

The Environment Agency's leaflet makes a bit of sense to me.
Dredging is usually for navigational purposes.

Dear me, Accyexplorer, you do post some twaddle. As Less said somewhere, you should stick to wandering round empty buildings or at least check the facts.

Network Rail owns all the fixed assets of our rail system and is responsible for their maintenance. Station,lines etc. The bulk of it's income comes from charging the train operators for using its assets. Any state money(up to 30% of its income) it receives is used on the assets.
Yes it is a private company but is has no shares, no shareholders and declares no profits or dividends. Specially set up by the Government( the Labour one) and can be taken over by the Government at any time at no cost.

It owns no rolling stock except the maintenance/repair trains so hasn't made anything out of ticket prices.
No shares, no divi so no Cameron personal profit.

The facts, stick to them.

I'm wondering if we have applied fer "AID" from other countries? after all we give enough when tragedy happens to them.,

Correct the significant factor is the hight of the land you are draining. In flat land with a river running through it the drains will normally be below the highest level the river can reach. Old drains were passive and produced the situation described. Modern drains should have pumps, but as with much of our infrastructure bringing things up to date tends to lag behind need.

I don't buy the global warming/cilmate change twaddle.

The weather has fluctuated since time began...there will always be times of severe weather in plaes around the globe...to believe that we are causing it is arrogant.......and anyway we produce less that 2% of global Co2 emissions......China, India and America are far and above the biggest culprits on that front...if you believe it, that is.
