TL;DR: The comparison of costs of nature-based defence projects and engineering structures show that salt-marshes and mangroves can be two to five times cheaper than a submerged breakwater for wave heights up to half a metre and, within their limits, become more cost effective at greater depths.

Defining coastal squeeze: A discussion
TL;DR: In the UK, the term "coastal squeeze" is commonly used to describe the loss of coastal habitats in front of sea defences as mentioned in this paper. But the definition of coastal squeeze has been ambiguous.
Journal ArticleDOI
Internal structure of mixed‐sand‐and‐gravel beach deposits revealed using ground‐penetrating radar
TL;DR: In this article, the authors used ground-penetrating radar (GPR) and photographic records of previous excavations to investigate the stratigraphy and internal sedimentary structure of mixed-beach deposits at Aldeburgh in Suffolk, south-east England.

A macroscale analysis of coastal steepening around the coast of England and Wales
Abstract: Coastal steepening potentially presents an array of management issues in the form of financial implications of sea defence degradation, increased risk posed to the hinterland as wave attenuation is reduced, 'coastal squeeze' and statutory requirements in the light of the Habitats Directive. The extent to which coastal steepening has occurred throughout England and Wales has been investigated through use of a GIS and dataset based on historical Ordnance Survey map information. Data were collected along 1084 selected profile lines, positioned so as to be geomorphologically representative of the coast. Features recorded from each map year included the positions of mean high water (MHW) and mean low water (MLW), the relative movements of which infer changing intertidal gradients. The results presented in this paper are on a subject and scale not previously published. It is revealed that 61% of the coastline studied has experienced a tendency towards steepening. Of the remainder, 33% has flattened, and 6% has experienced no rotational movement. This tendency towards steepening has been the dominant movement on each of the west, south, and east coasts.

Nature-based solutions: lessons from around the world
TL;DR: In this article, the authors consider an emerging group of coastal management approaches that offer the potential to reduce coastal flood and erosion risks while also providing nature conservation, aesthetic and amenity benefits.
