About the River Lavant

The River Lavant is a chalk river winterbourne that rises at East Dean and flows west to Singleton, then south past West Dean and Lavant to Chichester. From east of Chichester its natural course was south to the sea at Pagham, but the Romans diverted it to flow around the southern walls of Chichester and then west into Chichester Harbour.
