Reed (plant) in the context of "River Tay"

A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor (anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus.

Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges. Swamps are dominated by woody vegetation such as trees and shrubs (although reed swamps in Europe are dominated by reeds, not trees). Mangrove forest are wetlands with mangroves and halophytic woody plants that have evolved to tolerate salty water.

A river island is any exposed landmass surrounded by river water. Properly defined, it excludes shoals between seasonally varying flows and may exclude semi-coastal islands in river deltas such as Marajó.

These islands result from changes in the course of a river. Such changes may be caused by interactions with a tributary, or by the opposing fluvial actions of deposition and/or erosion that form a natural cut and meander. Nascent vegetation-free shoals and mudflats may dissipate and shift or build up into such islands through deposition; the process may be assisted through artificial reinforcement or natural factors, such as reeds, palms, evergreen trees or willows, that act as obstacles or erosion barriers, so that water flows around them. Islands may be small or large, covering many square kilometers, examples of which are given below.

In the Ancient Near East, clay tablets (Akkadian ṭuppu(m) 𒁾) were used as a writing medium, especially for writing in cuneiform, throughout the Bronze Age and well into the Iron Age.

Cuneiform characters were imprinted on a wet clay tablet with a stylus often made of reed (reed pen). Once written upon, many tablets were dried in the sun or air, remaining fragile. Later, these unfired clay tablets could be soaked in water and recycled into new clean tablets. Other tablets, once written, were either deliberately fired in hot kilns, or inadvertently fired when buildings were burnt down by accident or during conflict, making them hard and durable. Collections of these clay documents made up the first archives. They were at the root of the first libraries. Tens of thousands of written tablets, including many fragments, have been found in the Middle East.

A reedbed or reed bed is a natural habitat found in floodplains, waterlogged depressions and estuaries. Reedbeds are part of a succession from young reeds colonising open water or wet ground through a gradation of increasingly dry ground. As reedbeds age, they build up a considerable litter layer that eventually rises above the water level and that ultimately provides opportunities in the form of new areas for larger terrestrial plants such as shrubs and trees to colonise.

Artificial reedbeds are used to remove pollutants from greywater, and are also called constructed wetlands.

A pan flute (also known as panpipes or syrinx) is a musical instrument based on the principle of the closed tube, consisting of multiple pipes of gradually increasing length (and occasionally girth). Multiple varieties of pan flutes have been popular as folk instruments. The pipes are typically made from bamboo, giant cane, or local reeds. Other materials include wood, plastic, metal, and clay.

Wicker is a method of weaving used to make products such as furniture and baskets, as well as a descriptor to classify such products. It is the oldest furniture making method known to history, dating as far back as c. 3000 BC. Wicker was first documented in ancient Egypt, then having been made from pliable plant material, but in modern times it is made from any pliable, easily woven material. The word wicker or "wisker" is believed to be of Scandinavian origin: vika, which means "to fold" in Swedish. Wicker is traditionally made of material of plant origin, such as willow, rattan, reed, and bamboo, though the term also applies to products woven from synthetic fibers. Wicker is light yet sturdy, making it suitable for items that will be moved often like porch and patio furniture. Rushwork and wickerwork are terms used in England. A typical braiding pattern is called Wiener Geflecht, Viennese braiding, as it was invented in 18th century Vienna and later most prominently used with the Thonet coffeehouse chair.

The Asopos (Greek: Ασωπός, referred to in Latin sources as Asopus) is a river in Boeotia and northern Attica, Greece. In antiquity, it formed the border between the cities of Thebes and Plataea. The Battle of Plataea was fought on its banks. According to Pausanias (5.14.3) the Boeotian Asopus can produce the tallest reeds of any river.

Its source is on the northern slope of the Cithaeron mountain, southwest of Thebes. It empties into the South Euboean Gulf, near Skala Oropou. Its total length is 57 km. Its basin is 718 km. The Asopos flows along the following places, from the source downstream: Lefktra, Agios Thomas, Oinofyta, Sykamino, Skala Oropou. The river is polluted with hexavalent chromium due to industrial activity.

Phragmites (/fræɡˈmaɪtiːz/) is a genus of four species of large perennial reed grasses found in wetlands throughout temperate and tropical regions of the world.
