Received: 30 May 2014; in revised form: 7 July 2014 / Accepted: 18 July 2014 / Published: 25 July 2014 Abstract: Atoll islands are subject to a variety of processes that influence their geomorphological development. Analysis of historical shoreline changes using remotely sensed images has become an efficient approach to both quantify past changes and estimate future island response. However, the detection of long-term changes in beach width is challenging mainly for two reasons: first, data availability is limited for many remote Pacific islands. Second, beach environments are highly dynamic and strongly influenced by seasonal or episodic shoreline oscillations. Consequently, remote-sensing studies on beach morphodynamics of atoll islands deal with dynamic features covered by a low sampling frequency. Here we present a study of beach dynamics for nine islands on Takú Atoll, Papua New Guinea, over a seven-decade period. A considerable chronological gap between aerial photographs and satellite images was addressed by applying a new method that reweighted positions of the beach limit by identifying “outlier” shoreline positions.

NOTE-TAKING STRATEGY The stone pillars, or sea stacks, in the photograph above are a major Remember to organize tourist attraction in Port Campbell National Park. They were formed your notes in a chart or web as you read. by the movement of water. The constant action of waves breaking against the cliffs slowly wore them away, leaving behind pillarlike formations. Waves continue to wear down the pillars and cliffs at the rate of about two centimeters (one inch) a year. In the years to come, the waves will likely wear away the stone pillars completely. The force of waves, powered by wind, can wear away rock and move thousands of tons of sand on beaches. The force of wind itself can change the look of the land. Moving air can pick up sand particles and move them around to build up dunes. Wind can also carry huge amounts of fine sediment thousands of kilometers.

  • Narrowneck Artificial Reef: Construction
    Narrowneck Artificial Reef: Construction Our coastline is a dynamic system. Sand travels north via a process called longshore drift. At the same time, there is a cycle of erosion and accretion taking place, driven by wave action. Narrowneck was identified as requiring coastal management works in the mid-1990s in order to retain a more permanent supply of sand on the visible portion of the beach to satisfy tourist and local demand, and to stabilise the coastline. To achieve this objective, the Northern Gold Coast Beach Protection Strategy was established in 1999. Its objectives were to: ♦ Widen the beach and dunes along the Surfers Paradise Esplanade to increase the volume of sand within the storm buffer and provide more open space. The Reef was a key feature of the Northern Gold Coast Beach ♦ Protection Strategy, delivered by a partnership between Gold Coast To improve surf quality and recreational City Council and Griffith University Centre for Coastal Management. amenity at Narrowneck by the construction of Its design was informed by extensive numerical and physical a submerged reef to stabilise the nourished modelling.

Erosion is the periodic movement of sediments from the visible portion of a beach (during rough weather) to the submerged nearshore region. Sand will subside in one of these nearshore bars or compartments for a time before returning to the visible portion of the Aerial view of Narrowneck Artificial Reef (Source: Skyepics 2011) beach (during calmer periods) through the process of accretion.

  • Where Has Our Beach Gone? the Impacts of the UK’S 2014 Storms Paul Russell, Gerd Masselink, Tim Scott, Daniel Conley and Mark Davidson
    Where has our beach gone? The impacts of the UK’s 2014 storms Paul Russell, Gerd Masselink, Tim Scott, Daniel Conley and Mark Davidson Destructive storm waves tend to erode coasts and beaches, removing beach sand and gravel. A frequent question after a storm is, ‘Where has our beach gone?’ This article looks at where the beach sediment goes, what takes it there, whether it will come back and how long that recovery will take, and puts this in the context of the UK 2013/14 storms.

  • Coasts - Key Ideas L Coasts Are Temporary Structures, Often Subject to Rapid Change
    Coasts - Key Ideas l Coasts are temporary structures, often subject to rapid change. l The location of a coast depends on tectonic activity and the level of water in the ocean. l Coasts are classified as primary or secondary. l Human interference in coastal processes rarely increases the long term stability of a coast. 1 Classifying Coasts Coasts can be classified by a method that takes into account tectonic position and sea level. Primary coasts are young coasts dominated by terrestrial influences. Secondary coasts are older coasts that have been changed by marine influence. 2 1 Types of Primary Coasts • Drowned rivers • Coasts built out by land processes (e.g., rivers, glaciers) • Volcanic coasts • Coasts shaped by tectonic processes 3 Primary Coasts Many of the islands of Martha’s Vineyard and Nantucket are 4 examples of a primary coast. 2 Processes Shaping Coasts • Waves and currents • Stream erosion • Wind abrasion • Freeze/thaw cycles • Slumping 5 Secondary Coasts Waves are one of the forces that shape secondary coasts. 6 3 Alternative Classification of Coasts l Erosional Coasts l Features are: headlands, cliffs, stacks, arches, wave-cut platform l Depositional Coasts l Features are: barrier islands, deltas, glacial deposits 7 Other Types of Coasts l Drowned Coasts l Estuaries, fiords l Emergent or Uplifted Coasts l Uplifted marine terraces l Coasts affected by organisms l Reefs, mangroves 8 4 Beaches A beach is a zone of loose particles that covers a shore. Note that larger particles are associated with more sloped beach. 9 Features of Beaches • berm • berm crest • backshore • foreshore • beach scarp • longshore trough • longshore bars 10 5 11 Beaches The features of a beach.
