Nailbourne rises again

A delivery driver drives through the ford formed by the river Nailbourne in Barham, Kent as it rises again after all the rainfall of recent months..Information below is taken from an Environment Agency Briefing Note...Link: http://www.barham-kent.org.uk/Groundwater_Briefing_Note_Kent_090113.pdf.Flooding from groundwater .Nailbourne and Little Stour 9 January 2013 .Current situation .After one of the wettest years ever recorded, groundwater levels around the Nailbourne, Little Stour and Petham Bourne are high. Groundwater levels in these areas are continuing to rise in response to the recent rainfall. The rate that the groundwater is increasing for the Nailbourne has reduced since the river has started to flow. However, the levels are still increasing but at a slower rate. .The ground along the Petham Bourne is currently wet but not flowing. The groundwater levels for this area are also rising slowly. .It can take time for rainfall to soak through the ground into the groundwater. This delay is why we are monitoring groundwater level increases. As groundwater levels are high, any further substantial rainfall is likely to cause a further rise in water levels and could lead to flooding of property. .Current groundwater levels are comparable to those experienced in 2010 where impacts to sewerage systems and some roads were experienced. This lasted for several months. Improvements have been made to flood resilience and drainage infrastructure as well as the sewerage systems since 2010. We have also managed the river throughout the year in case a situation like this occurred. .The Nailbourne is currently flowing between Lyminge and at a point upstream of Barham. There is also limited flow from downstream of Bourne Park to a point upstream of Bridge. These flows are what would be expected from the current groundwater levels....
