Gatwick airport flooded in 2013. The river Mole runs around the airport and sometime between 1999 and 2013 the bank fell in and encroached 350m above the airport boundary as per the Google pictures below. I wonder if this had anything to do with it? 1999 was probably in flood but the river is restricted by 2013 and much wider above and below this point. Please maintain and dredge the rivers.
