The River Bourne rises in the parish of Ightham, Kent and flows in a generally south easterly direction through the parishes of Borough Green, Platt, Plaxtol, West Peckham, Hadlow, and East Peckham where it joins the River Medway. In the 18th century the river was known as the Busty or Buster, the Shode or Sheet, but is not known by these names nowadays.
