This discussion continues to look at severe erosion at the coastal community of Hemsby in Norfolk. Previous discussions considered Scarps and the effects of Lowering and Steepening on a Beach profile when the Sea Comes In. This latest discussion will consider how the tides, sandbanks and beach interact in a mobile, fluid environment on a…

Scarp cut into sand behind rocks at Hemsby Gap after storm on 20th April 2023 The precarious position of homes on the Marrams in Hemsby has been highlighted in a BBC documentary Life on The Edge. The vulnerability of the community on this coastline was exposed again when a storm on 20th of April saw…

Coastal Erosion features known as Scarps, are defined as almost vertical sea-facing walls, cut into sandy beaches or cliffs. Examples of Scarps have been seen recently at Hemsby Gap, where a 10 ft drop was cut into the beach and at Crantock Beach in Cornwall, where a 20 ft drop has been cut into the…

A recent discussion on alteredmarshes looked at a Skew Surge, the total difference between Maximum Predicted Tide Height and Maximum Observed High Water. It suggested the measure could aid storm analysis by suggesting specific conditions capable of generating a surge. However, information, such as the depth and size of a low-pressure system, whether the sea…

As Red House in Thorpeness on North End Avenue is been demolished, because of coastal erosion, this discussion will conclude the series to discuss whether large-scale events or small gradual processes contribute the most to erosion. The previous discussion about Thorpeness, the penultimate in the series, looked at the acute erosion on the beach in…

Shadowlands. Matthew Green The penultimate discussion in the series to consider whether large events or small gradual processes contribute the most to coastal erosion, will look at the beach and cliffs of Thorpeness. This area has been subject to gradual long-term erosion, but it is also a dynamic high-energy location where several metres of cliff…

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…

“The winds of a thousand miles buffeted and blew, wind over tide, wave over beach, the whole force of accumulated energy finally crashing up against our cliff” Easternmost House, Juliet Blaxland. This post uses a combination of mediums to discuss a period of high waves at the chosen locations of Lowestoft and Felixstowe on 31st…
