A look at the nature of the Alde & Ore, its locations, characteristics and the impact of its tidal fortunes.

Following recent high waves and strong winds on the East Anglian coast, it is perhaps appropriate to announce the 5-year anniversary of the blog Altered Coast and its previous incarnation Altered Marshes. The original inclusion of the word marshes is due to a visit in 2020 to Hazlewood marshes, an intertidal reserve next to the…

This discussion is the second of a series, to debate whether big events, such as surges or high waves, or smaller gradual processes, cause the most erosion. This second conversation will look at erosion at Hazelwood Marshes in the Alde and Ore Estuary and Sudbourne Beach on the open coast. These areas have been selected…

In the lead-up to the two-year anniversary of alteredmarshes, a series of discussions will consider whether it is the big storm surge events that cause the most coastal erosion, or smaller processes that develop over a long period, that weaken flood defences and erode shingle and cliffs. The first of these discussions will consider The…

Recent information from the Alde and Ore Community Partnership has found the remaining walls at Hazelwood marshes could be at new risk of erosion. This is due large volumes of tidal water forming waves, which when driven by northerly winds risk weakening the rear inland side of the walls. It is thought that there is…

On the right-hand corner of Iken marshes, there is a freshwater marsh nature reserve, near Stanny House Farm, just below the Alde Mud Flats, on the Alde Ore Estuary. The reserve is home to Marsh Harriers and Lapwings, as well as Bearded Tits, which nest in the Reedbeds. It is on the right-hand side of…

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…

Iken Cliff, near the Snape Maltings, in the Alde Ore estuary, is an area backed by sandy cliffs, fronted by reed beds and salting’s and boat moorings. One noticeable feature is the presence of breached flood defences. One cause of breaches in flood defences is a process known as desiccated cracking, which involves flood water…

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…

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.…
