A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes, with little or no vegetation, are called ergs or sand seas. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter slip face in the lee side. The valley or trough between dunes is called a dune slack.
A beach is a landform alongside a body of water which consists of loose particles. The particles composing a beach are typically made from rock, such as sand, gravel, shingle, pebbles, etc., or biological sources, such as mollusc shells or coralline algae. Sediments settle in different densities and structures, depending on the local wave action and weather, creating different textures, colors and gradients or layers of material.
Matthiola is a genus of flowering plant in the mustard family Brassicaceae. It is named after Italian naturalist Pietro Andrea Mattioli (1501–1577). The genus contains about 50 species of annual, biennial and perennial herbaceous plants and subshrubs. Many are cultivated for their heavily scented, colorful flowers.

Although unrelated to true ivy, it is commonly known as Boston ivy, grape ivy, and Japanese ivy, and also as Japanese creeper, and by the name woodbine.
Coastal management is defence against flooding and erosion, and techniques that stop erosion to claim lands. Protection against rising sea levels in the 21st century is crucial, as sea level rise accelerates due to climate change. Changes in sea level damage beaches and coastal systems are expected to rise at an increasing rate, causing coastal sediments to be disturbed by tidal energy.
Guadalupe-Nipomo Dunes is the largest remaining dune system south of San Francisco and the second largest in the U.S. state of California. It encompasses an 18-mile (29 km) stretch of coastline on the Central Coast of California and extends from southern San Luis Obispo County to northern Santa Barbara County.
The Swan Coastal Plain in Western Australia is the geographic feature which contains the Swan River as it travels west to the Indian Ocean. The coastal plain continues well beyond the boundaries of the Swan River and its tributaries, as a geological and biological zone, one of Western Australia's Interim Biogeographic Regionalisation for Australia regions. It is also one of the distinct physiographic provinces of the larger West Australian Shield division.
Sand dune ecology describes the biological and physico-chemical interactions that are a characteristic of sand dunes.
Sand dune stabilization is a coastal management practice designed to prevent erosion of sand dunes. Sand dunes are common features of shoreline and desert environments. Dunes provide habitat for highly specialized plants and animals, including rare and endangered species. They can protect beaches from erosion and recruit sand to eroded beaches. Dunes are threatened by human activity, both intentional and unintentional. Countries such as the United States, Australia, Canada, New Zealand, the United Kingdom, and Netherlands, operate significant dune protection programs.
Matthiola incana is a species of flowering plant in the cabbage family Brassicaceae. Common names include Brompton stock, common stock, hoary stock, ten-week stock, and gilly-flower. The common name stock usually refers to this species, though it may also be applied to the whole genus Matthiola. The common name "night-scented stock" or "evening-scented stock" is applied to Matthiola longipetala.
The Guadalupe-Nipomo Dunes National Wildlife Refuge is a 2,553-acre (10.33 km2) protected area located along the Central Coast of California, in southern San Luis Obispo and northern Santa Barbara Counties.
Cape Flats Dune Strandveld is an endangered vegetation type. This is a unique type of Cape Strandveld that is endemic to the coastal areas around Cape Town, including the Cape Flats.
A nabkha, nebkha or nebka is a type of sand dune. Other terms used include coppice dune and dune hummock or hummocky dune, but these more accurately refer to similar, but different, sand dune types. Authors have also used the terms phytogenic hillock, bush-mound, shrub-coppice dune, knob dune, dune tumulus, rebdou, nebbe, and takouit.
Matthiola sinuata, commonly known as sea stock, is a coastal plant in the family Brassicaceae.
Matthiola fruticulosa, the sad stock or dark-flowered stock, is a species of flowering plant in the family Brassicaceae, native to the Mediterranean region. It is adapted to clay and marl soil types.
The Lava is a coastal stream in the west of the department of Corse-du-Sud, Corsica, France.
Matthiola lunata is a species of plant in the family Brassicaceae.
