West of Henfield, the two branches of the river meet before flowing between Upper Beeding and Bramber, past Coombes, through a gap in the South Downs near Lancing College where the Adur is fed by the Ladywell Stream. The river continues on to the English Channel at Shoreham-by-Sea. The mouth of the Adur is now two miles (3 km) from the town centre of Shoreham due to longshore drift. Previously, the river mouth was further east, in Portslade, but an opening to the sea was made which allowed the creation of Southwick Ship Canal.
