Severe erosion continues at Thorpeness beach, particularly on the section of beach below North End Avenue. The most noticeable features include substantial damage to flood defences, a loss of material and retreat of the cliff face, scouring at the base of the cliffs and a significant loss of shingle. Flood defences have been in place…

This discussion will consider three particular elements to the on-going dramatic erosion at Thorpeness. The first element is the flood defences installed in a series of attempts to hold back the sea. A Gabion defence, a stone filled mesh box was installed in 1976, following serious erosion with beach material added to cover the defence.…

Hazlewood marshes provides unique biodiversity in an environment moulded by its fortunes as an intertidal reserve. Sediment deposits are accreting at Hazelwood, noticeably in the former freshwater channels. The sediment is thought to consist of estuarine silt, which could concur with analysis that describes the Alde Ore estuary as flood-dominant, i.e that it has a…

In a continuation of discussions about Sudbourne beach, south of the Martello Tower in Aldeburgh, Suffolk, consideration will be given to the current position of Sudbourne beach. Thanks to access granted by the Environment Agency, it has been possible to get a recent visual image of the dynamic interplay between the sea, the shingle ridge…

A selection of photos taken in February 2021 show the current landscape of Aldeburgh Marshes and Hazlewood marshes as well as the history of the scouring effects of the tidal surge in December 2013. The first photo shows the lasting affects of the scouring of the trees at the back of Hazlewood marshes, alongside the…

This piece seeks to provide a brief update to a previous piece on Sudbourne Beach, which is a shingle spit south of Aldeburgh on the Suffolk coast. A public consultation was held between 1 October – 30 November 2019 regarding the policy of the Coastal Partnerships East and East Suffolk Council Shoreline Management Plan (SMP)…

In field studies on the Essex and Kent coasts following the North Sea 1953 storm surge, academics, Cooling and Marsland listed four possible causes for flood embankment failure. Three of these causes are particularly useful to consider regarding the failure of river walls at Hazelwood marshes and Havergate Island. These are, a) erosion of sea-facing…

Havergate Island is situated near the Suffolk village of Orford, at the meeting of the Ore and the Butley rivers. The Ore divides in two around the two-mile long Havergate Island with flows splitting through what is known as the Gull on the north side of island and the Narrows on the south of island.…

Sudbourne Beach situated south of the Martello Tower near Aldeburgh on the Suffolk coast is a shingle spit that separates the open coast from the Alde/Ore estuary. Recently, the sea has eroded the shingle spit at a greater rate than has previously been experienced. Coastal Partnerships East and East Suffolk Council have a Shoreline Management…

The Alde-Ore Estuary, of which Hazelwood marshes is an intertidal component, is long and thin with two main sections. The upper estuary, the Alde refers to the area between Snape and Halfway Reach, an area south of Slaughden next to the radio station below Lantern Marshes. The area of the estuary from Halfway Reach to…
