A new typology for Portuguese beaches: An exploratory study

Bruno Vaz, Allan T Williams, Carlos Pereira da Silva, Ergin Aysen

Journal of Coastal Conservation > 2017 > 21 > 1 > 95-103

Beaches are now the most popular tourist destination and increased demand in the past 40 years has led not only to beach congestion but also to a differentiation between urban (resorts, overcrowded and under huge pressure), to natural (less crowded beaches). This diversity needs to be further explored not only to characterize individual beaches in a precise way, but also to understand the distinctive...

Omar A. Alharbi, Allan T. Williams, Michael R. Phillips, Tony Thomas

Arabian Journal of Geosciences > 2016 > 9 > 19 > 1-15

A lack of understanding exists of the origin and textural characteristics of Saudi Arabian Red Sea coastal sediments. This paper concerns the southern coastline of Jizan on the Saudi Red Sea. It is some 160 km long characterised by either narrow rocky headlands with intermittent pocket beaches or wide low-lying beaches dissected by wadis. Granulometric testing of samples from 135 locations showed...

Sand colour at Cuba and its influence on beach nourishment and management

Enzo Pranzini, Giorgio Anfuso, Camilo-Mateo Botero, Alfredo Cabrera, more

Ocean & Coastal Management > 2016 > 126 > C > 51-60

The colour of 93 beaches in Cuba was assessed in CIEL*a*b* colour space. Study sites comprised exposed and sheltered mainland beaches and keys. Notwithstanding the limited extension of this country, beaches show real colour variability due to mineralogical differences in rock outcrops in the various watersheds, the proximity of the coral reef and the shell fragments originated in open coast or mangrove...

Aspects of coastal erosion and protection in Europe

Enzo Pranzini, Lilian Wetzel, Allan T. Williams

Journal of Coastal Conservation > 2015 > 19 > 4 > 445-459

The wide variety of physical, political, economic and cultural attributes along European coasts has led to different national management approaches to coastal protection. In all countries, this became problematic when the coast underwent anthropogenic impact and acquired relevant economic value for uses, such as, transport, military, tourism or conservation. However, common ground technology developed...

Links between wave forcing, offshore islands and a macro‐tidal headland‐bound bay beach

Tony Thomas, Michael R. Phillips, Allan T. Williams, Rhian E. Jenkins

Earth Surface Processes and Landforms > 39 > 2 > 143 - 155

Profiles were analysed in conjunction with wave climate to assess offshore island influences on an embayed beach at Tenby, Wales. Time series analyses showed medium and short‐term beach oscillation, with volume exchanges between zones lagging by up to six months. Dominant southerly and southwesterly waves caused sub and low tidal longshore drift from south towards north, while less frequent southeasterly...

Blue Flag or Red Herring: Do beach awards encourage the public to visit beaches?

John McKenna, Allan T. Williams, J. Andrew G. Cooper

Tourism Management > 2011 > 32 > 3 > 576-588

Surveys of beach visitor motivation in Ireland, Wales, Turkey and the USA indicate that beach awards play an insignificant role in motivation to visit beaches. However, a number of criteria closely identified with awards, notably cleanliness and water quality, are revealed to be very important. Aesthetic and emotional factors such as scenic setting and general ambience, and practical concerns such...

Development of a ‘Matrix Scoring Technique’ to determine litter sources at a Bristol Channel beach

David T. Tudor, Allan T. Williams

Journal of Coastal Conservation > 2004 > 10 > 1-2 > 119-127

Litter at beaches can come from more than one source and determining the proportions to assign pollution to different sources is very complex. There is no widely accepted methodology at present that links litter items to their source. The aim of this study was to create a method of assigning a source to litter found on beaches of the Bristol Channel but which could equally be used on any beach. Various...

Application of function analysis to bathing areas in the Maltese Islands

Anton S. Micallef, Allan T. Williams

Journal of Coastal Conservation > 2003 > 9 > 2 > 147-158

On a small island such as Malta where many developers and policy makers place a large emphasis on social use and develoment values, which encourages recreational/industrial development, it is often hard to promote the monetary value of coastal conservation due to strong competition with the large tourism industry. An assessment of the ecological (conservation) and economic (use/development) values...
