High Water Marks
A high water mark is a point that represents the maximum rise of a body of water over land. Such a mark is often the result of a flood, but high water marks may reflect an all-time high, an annual high (highest level to which water rose that year) or the high point for some other division of time. Knowledge of the high water mark for an area is useful in managing the development of that area, particularly in making preparations for flood surges. High water marks from floods have been measured for planning purposes since at least as far back as the civilizations of ancient Egypt. It is a common practice to create a physical marker indicating one or more of the highest water marks for an area, usually with a line at the level to which the water rose, and a notation of the date on which this high water mark was set. This may be a free-standing flood level sign or other marker, or it may be affixed to a building or other structure that was standing at the time of the flood that ...

FEMA - 30685 - Flood High Water Mark In Missouri
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President that FEMA and the federal government respond to the disaster. The only exception to the state's gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, or the Space Shuttle ''Columbia'' in the 2003 return-flight disaster. While on-the ...

North Cornwall District Council
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

The Heritage Coast
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

Pied Wagtail
The white wagtail (''Motacilla alba'') is a small passerine bird in the family Motacillidae, which also includes pipits and longclaws. The species breeds in much of Europe and the Asian Palearctic and parts of North Africa. It has a toehold in Alaska as a scarce breeder. It is resident in the mildest parts of its range, but otherwise migrates to Africa. In Ireland and Great Britain, the darker subspecies, the pied wagtail or water wagtail (''M. a. yarrellii'') predominates; this is also called in Ireland willie wagtail, not to be confused with the Australian species ''Rhipidura leucophrys'' which bears the same common name. In total, there are between 9 and 11 subspecies of ''M. alba''. The white wagtail is an insectivorous bird of open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas it has adapted to foraging on paved areas such as car parks. It nests in crevices in stone walls and similar natura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turnstone
Turnstones are two bird species that comprise the genus ''Arenaria'' in the family Scolopacidae. They are closely related to calidrid sandpipers and might be considered members of the tribe Calidriini. The genus ''Arenaria'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the ruddy turnstone (''Arenaria interpres'') as the type species. The genus name ''arenaria'' is from Latin ''arenarius'', "inhabiting sand", from ''arena'', "sand". The genus contains two species: the ruddy turnstone (''Arenaria interpres'') and the black turnstone (''Arenaria melanocephala''). Both birds are waders. Their length is typically between 20 and 25 cm, with a wingspan between 50 and 60 cm and a body mass between 110 and 130g. For waders their build is stocky, with short, slightly upturned, wedge shaped bills. They have white patches on the back, wings and tail. They are high Arctic breeders, and are migratory. Their strong necks and powerful, slightly upturn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Rock Pipit
The European rock pipit (''Anthus petrosus''), or just rock pipit, is a species of small passerine bird that breeds in western Europe on rocky coasts. It has streaked greyish-brown upperparts and buff underparts, and is similar in appearance to other European pipits. There are three subspecies, of which only the Fennoscandian form is migratory, wintering in shoreline habitats further south in Europe. The European rock pipit is territorial at least in the breeding season, and year-round where it is resident. Males will sometimes enter an adjacent territory to assist the resident in repelling an intruder, behaviour only otherwise known from the African fiddler crab. European rock pipits construct a cup nest under coastal vegetation or in cliff crevices and lay four to six speckled pale grey eggs which hatch in about two weeks with a further 16 days to fledging. Although insects are occasionally caught in flight, the pipits feed mainly on small invertebrates picked off the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wader
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Coelopa Frigida
''Coelopa frigida'' is a species of seaweed fly or kelp fly. It is the most widely distributed species of seaweed fly. It can be found on most shorelines in the temperate Northern Hemisphere. Other species of seaweed flies include ''Coelopa nebularum'' and ''Coelopa pilipes''. ''C. frigida'' feeds primarily on seaweed, and groups of ''C. frigida'' flies tend to populate near bodies of water. Climate change has led to an increase in ''C. frigida'' blooms along shores, which creates a pest problem for human beach-goers. ''C. frigida'' is also an important organism for the study of sexual selection, particularly female choice, which is influenced by genetics. Description ''C. frigida'' are the most common seaweed fly. They tend to aggregate on beaches with an abundance of stranded algae, but occasionally swarm inland. Their physical features include a dark brown to black body, a set of lighter colored legs, and large, translucent wings. Males are typically larger than females, though ...

Seaweed Fly
Kelp fly is one common name of species of flies in a number of families of "true flies" or Diptera. They generally feed on stranded and rotting seaweed, particularly kelp in the wrack zone. When conditions are suitable they are very numerous and may be ecologically important in the turnover of organic material on the coast.Griffiths C. L.,Stenton-Dozey J. M. E.,Koop K.,1983, Kelp wrack and energy flow through a sandy beach. Sandy beaches as ecosystems, A. McLachlan & T. Erasmus (eds.), W. Junk,The Hague,547–556 In this role they also may be an important item in the diet of beach-dwelling animals and birds. The flies most generally referred to as kelp flies are the widely distributed Coelopidae, such as ''Coelopa pilipes''. In popular speech however, they are not clearly distinguished from other flies with similar feeding habits, such as the Heterocheilidae, the Helcomyzinae and sundry members of the Anthomyiidae The Anthomyiidae are a large and diverse family of Muscoidea f ...

Talitrus Saltator
''Talitrus saltator'', a species of sand hopper, is a common amphipod crustacean of sandy coasts around Europe. The animal's typical "hopping" movement gives it its common name, and is produced by a flexion of the abdomen. In order to do this, it must stand on its legs (amphipods usually rest on their sides) and suddenly extend its abdomen from under its body. It can thus leap several inches into the air, although without any control over its direction. A great deal of scientific research has been carried out on the animal, to determine the environmental cues which it uses to control its behavior. Description ''Talitrus saltator'' reaches lengths between and , with males being slightly larger than females. The body is grayish-brown or grayish-green in colour, with a single pair of black eyes. It has a distinct pair of antennae, with one antenna as more robust than the other. Distribution ''Talitrus saltator'' is found around the coasts of the North Sea and north-east Atlant ...

Sandhopper
Talitridae is a family of amphipods. Terrestrial species are often referred to as landhoppers and beach dwellers are called sandhoppers or sand fleas. The name sand flea is misleading, though, because these talitrid amphipods are not siphonapterans (true fleas), do not bite people, and are not limited to sandy beaches. Marine amphipods are often washed up in the strandline, but die rapidly on drying out. Talitrids differ in being able to survive for a long time out of water; some Southern Hemisphere species are entirely terrestrial. It contains these genera: * '' Austropacifica'' Lowry & Springthorpe, 2019 * '' Floresorchestia'' Bousfield, 1984 * '' Gazia'' Lowry & Springthorpe, 2019 * ''Americorchestia'' Bousfield, 1991 * '' Asiaorchestia'' Lowry & Myers, 2019 * '' Britorchestia'' Lowry & Bopiah, 2012 * '' Persianorchestia'' Momtazi, Lowry & Hekmatara, 2017 * '' Pseudorchestoidea'' Bousfield, 1982 * '' Sardorchestia'' Ruffo in Tafani, Ugolini, Bazzicalupo, Mengoni & Ruffo, ...
