Changes to the River Meon Mouth

1500

The mouth of the River Meon has undergone dramatic changes over the centuries, and these changes have shaped the landscape and ecology of the Hill Head area. In the medieval period, the Meon had a broad, tidal estuary that extended some distance inland, with mudflats and saltmarshes flanking the river channel. The estuary was a productive fishing ground and a natural harbour for small boats. The construction of the Earl of Southampton's sea wall in the early seventeenth century fundamentally altered this system, cutting off the tidal flow and beginning the process of siltation that eventually created the freshwater marshes of Titchfield Haven. Over the following centuries, the river mouth became progressively narrower and shallower. The Meon now reaches the sea through a modest channel rather than a broad estuary, and the surrounding land has risen as sediment accumulated. These changes have affected the coastal processes at Hill Head, altering the patterns of longshore drift and sediment supply that determine the shape of the beach and the rate of cliff erosion. The river mouth area remains dynamic, with the channel shifting position over time and storm events periodically reshaping the beach.
