Question WThe London Road runs along a valley bottom, but where is or whatever happened to the river? There are many coombs or dry valleys across the Downs that were cut during the last ice age. When the ice retreated the glacial rivers ceased to flow. But the valley of the London Road has an intermittent river, one that flows when the winter rainfall is especially heavy. The water table in the chalk of the Downs rises to the surface and a stream flows down the London Road. It last happend in the very wet winter of 1999/2000. Despite our modern sewerage system and water pumping stations out on the Downs a steam flowed down the London Road during the wettest winter months. What is the name of this intermittent river?
