Major Southampton Uni Report Into Flooding Increase
Southampton University researchers have found the reason more people are suffering from flooding in the UK is a massive increase in housebuilding and population, over the past 129 years.
In one of the most comprehensive studies of its kind, scientists have discovered that although the number of reported floods has gone up during the 20th and 21st Century, this trend disappears when the figures are adjusted to reflect population growth and increased building numbers over the same period.
Published in the journal Hydrological Sciences, the study looks at data sets from 1884 to 2013 and found an upward trend in reported flooding, with flood events appearing more frequently towards the end of the 20th century, peaking in 2012 when annual rainfall was the second highest in over 100 years.
The rise in UK flood reports over the 20th Century coincides with population growth from 38.2 million to 59.1 million and a tripling in the number of houses, from 7.7 million to 24.8 million.

"As a result there were more properties exposed to flooding and more people to report flooding," says lead author Andrew Stevens. "A higher exposure to flooding will result in more reported flood events and larger potential damages."
The study found significant variation between decades in both the raw and adjusted data, with the years between 1908 -1934, 1977 - 1988 and 1998 - 2013 featuring a relatively high numbers of reported floods.
The effect of increasing and improving flood defences is unclear. While upgrades to artificial defences, like the Thames Barrier, have reduced the effect of extreme sea level events, natural flood defences may have declined over the study period.
"Attributing periods of reduced flood damage simply to the effects of improved management is difficult and must be done with care," says co-author Derek Clarke.
Professor Robert Nicholls added:
"These observations should not stop concern about future flood impacts, especially in coastal areas where faster sea-level rises are expected and areas potentially exposed to higher rainfall intensities. Future flood risk may be very sensitive to changes in funding or management approaches and this has important implications for decision makers."
Officers say many of those were after people didn't secure their car properly.
