A berm is a level space, shelf, or raised barrier (usually made of compacted soil ) separating areas in a vertical way, especially partway up a long slope. It can serve as a terrace road, track, path, a fortification line , a border / separation barrier for navigation, good drainage, industry, or other purposes.

47-484: The word is from Middle Dutch and came into usage in English via French. In medieval military engineering , a berm (or berme) was a level space between a parapet or defensive wall and an adjacent steep-walled ditch or moat . It was intended to reduce soil pressure on the walls of the excavated part to prevent its collapse. It also meant that debris dislodged from fortifications would not fall into (and fill)

94-433: A barrier to keep spills from reaching the ground or navigable waterways. Most berms have sidewalls to keep liquids contained for future capture and safe disposal. [REDACTED] Media related to Berms at Wikimedia Commons Middle Dutch Middle Dutch is a collective name for a number of closely related West Germanic dialects whose ancestor was Old Dutch . It was spoken and written between 1150 and 1500. Until

141-473: A berm is a noise barrier constructed of earth, often landscaped , running along a highway to protect adjacent land users from noise pollution . The shoulder of a road is also called a berm and in New Zealand the word describes a publicly owned grassed nature strip sometimes planted with trees alongside urban roads (usually called a verge). [1] In snowboard cross , a berm is a wall of snow built up in

188-409: A berm refers to dirt and rock piled alongside a haulage road or along the edge of a dump point. Intended as a safety measure, they are commonly required by government organizations to be at least half as tall as the wheels of the largest mining machine on-site. Physical security systems employ berms to exclude hostile vehicles and slow attackers on foot (similar to the military application without

235-418: A certain ruler also created a sphere of linguistic influence, with the language within the area becoming more homogeneous. Following, more or less, the political divisions of the time, several large dialect groups can be distinguished. However, the borders between them were not strong, and a dialect continuum existed between them, with spoken varieties near the edges of each dialect area showing more features of

282-491: A corner. In mountain biking , a berm is a banked turn formed by soil, commonly dug from the track, being deposited on the outer rim of the turn. In coastal systems, a berm is a raised ridge of pebbles or sand found at high tide or storm tide marks on a beach . In snow removal, a berm or windrow refers to the linear accumulation of snow cast aside by a plow . Earth berms are used above particle accelerator tunnels to provide shielding from radiation. In open-pit mining ,

329-414: A ditch or moat . In the trench warfare of World War I , the name was applied to a similar feature at the lip of a trench , which served mainly as an elbow-rest for riflemen . In modern military engineering, a berm is the earthen or sod wall or parapet, especially a low earthen wall adjacent to a ditch. The digging of the ditch (often by a bulldozer or military engineering vehicle ) can provide

376-519: A labial or velar consonant. Some former class 1 weak verbs retained so-called Rückumlaut . These verbs had undergone umlaut in the present tense, but the umlaut-triggering vowel was syncopated in the past tense already in Old Dutch, preventing umlaut from taking hold there. Thus, senden had the first- and third-person singular past tense sande . These verbs tended to be reinterpreted as strong verbs in later Middle Dutch; sande itself gave rise to

423-433: A word could be found spelled differently in different occurrences within the same text. There was the matter of personal taste, and many writers thought it was more aesthetic to follow French or Latin practice, leading to sometimes rather unusual spellings. The spelling was generally phonetic, and words were written based on how they were spoken rather than based on underlying phonemes or morphology. Final-obstruent devoicing

470-475: Is piled up against exterior walls and packed, sloping down away from the house. The roof may or may not be fully earth covered, and windows/openings may occur on one or more sides of the shelter. Due to the building being above ground, fewer moisture problems are associated with earth berming in comparison to underground/fully recessed construction. For general applications, a berm is a physical, stationary barrier of some kind. For example, in highway construction,

517-568: Is unclear. The following can be said: The vowels /eɛ̯/ , /øœ̯/ and /oɔ̯/ , termed "sharp-long" and denoted with a circumflex ê ô , developed from Old Dutch long vowels. The opening diphthong pronunciation was probably widespread, and perhaps once universal, as it is nowadays still found in both West Flemish and in Limburgish, at opposite ends of the Middle Dutch language area. In the general area in between, including standard Dutch,

564-593: The 13th century. Its characteristics are: Hollandic was spoken in the County of Holland . It was less influential during most of the Middle Ages but became more so in the 16th century during the "Hollandic expansion", during which the Eighty Years' War took place in the south. It shows the following properties: Limburgish was spoken by the people in the provinces of modern Dutch and Belgian Limburg . It

611-401: The Middle Dutch period. The consonants of Middle Dutch differed little from those of Old Dutch. The most prominent change is the loss of dental fricatives. In addition the sound [z] was phonemicised during this period, judging from loanwords that retain [s] to this day. For descriptions of the sounds and definitions of the terms, follow the links on the headings. Notes: Most notable in

658-408: The Middle Dutch period. A new second person plural pronoun was created by contraction of gij/jij and lui ('people') forming gullie/jullie (literally, 'you people'). Note: There are several other forms. Definite Article ( die , dat = the) Middle Dutch mostly retained the Old Dutch verb system. Like all Germanic languages, it distinguished strong , weak and preterite-present verbs as

705-467: The Middle Dutch vowel system, when compared to Old Dutch, is the appearance of phonemic rounded front vowels, and the merger of all unstressed short vowels. Long vowels and diphthongs cannot be clearly distinguished in Middle Dutch, as many long vowels had or developed a diphthongal quality, while existing diphthongs could also develop into monophthongs. Sometimes, this occurred only in restricted dialects, other developments were widespread. Many details of

752-624: The Old Dutch long ā , and "soft-long" ā being the result of lengthening. These two vowels were distinguished only in Limburgish and Low Rhenish at the eastern end, and in western Flemish and coastal Hollandic on the western end. The relative backness of the two vowels was opposite in the two areas that distinguished them. The closing diphthong /ɛi̯/ remained from the corresponding Old Dutch diphthong. It occurred primarily in umlauting environments, with /eɛ̯/ appearing otherwise. Some dialects, particularly further west, had /eɛ̯/ in all environments (thus cleene next to cleine ). Limburgish preserved

799-463: The advent of Modern Dutch after 1500 or c.  1550 , there was no overarching standard language , but all dialects were mutually intelligible. During that period, a rich Medieval Dutch literature developed, which had not yet existed during Old Dutch . The various literary works of the time are often very readable for speakers of Modern Dutch since Dutch is a rather conservative language. Several phonological changes occurred leading up to

846-413: The dative singular, a remnant of the late Old Dutch inflection. In some rare occasions, the genitive singular was also endingless. Some nouns ended in -e in the singular also; these were primarily former ja-stems, which were masculine or neuter. A few were former i-stems with short stems. Nouns of this type tended to be drawn into the weak inflection by analogy. The following table shows the inflection of

893-499: The diphthong wherever it was preserved in High German. The closing diphthong /ɔu̯/ has two different origins. In the vast majority of the Middle Dutch area, it developed through l-vocalization from older /ol/ and /al/ followed by a dental consonant. In the eastern area, Limburg in particular, it was a remnant of the older diphthong as in High German, which had developed into /oɔ̯/ elsewhere. L-vocalization occurred only in

940-430: The distinction was mostly lost. Class 3, which retained a clear distinction that did not rely on vowel length, was levelled in favour of the o of the plural. In classes with a lengthened vowel in the present, the singular imperative often appears with a short vowel instead, e.g. les , drach . An alternative form, with final -e by analogy with the weak verbs, also occurs. The eastern dialects occasionally show i in

987-436: The exact phonetics are uncertain, and seemed to have differed by dialect. The overall system is clear, however, as almost all the vowels remain distinct in modern Limburgish: /iː/ , /iə̯/ , /eɛ̯/ , /eː/ and /aː/ appear in modern Limburgish as /iː/ , /eː/ , /iə̯/ , /æː/ and /aː/ respectively. The vowels /ie̯/ , /yø̯/ and /uo̯/ developed from Old Dutch opening diphthongs, but their exact character in Middle Dutch

1034-454: The former ja-stems, had an -e even in the strong and copular form, e.g. die vrouwe is clein e "the lady is small". Middle Dutch pronouns differed little from their modern counterparts. The main differences were in the second person with the development of a T-V distinction . The second-person plural pronoun ghi slowly gained use as a respectful second-person singular form. The original singular pronoun du gradually fell out of use during

1081-650: The game from the top of the hill. Berms are also used as a method of environmental spill containment and liquid spill control. Bunding is the construction of a secondary impermeable barrier around and beneath storage or processing plant, sufficient to contain the plant's volume after a spill. This is often achieved on large sites by surrounding the plant with a berm. The US Environmental Protection Agency (EPA) requires that oils and fuels stored over certain volume levels be placed in secondary spill containment. Berms for spill containment are typically manufactured from polyvinyl chloride (PVC) or geomembrane fabric that provide

1128-524: The language. The general practice was to write long vowels with a single letter in an open syllable and with two letters in a closed syllable. Which two letters were used varied among texts. Some texts, especially those in the east, do not do so and write long vowels with a single letter in all cases (as is the predominant rule in modern German). Middle Dutch nouns inflected for number as well as case . The weakening of unstressed syllables merged many different Old Dutch classes of nominal declension. The result

1175-481: The masculine noun dach "day", feminine dâet "deed" and neuter brôot "bread". Weak nouns were characterised by the ending -en throughout the plural. The singular ended in -e . The following table shows the inflection of the masculine noun bōge "bow, arc". Middle Dutch adjectives inflected according to the gender, case and number of the noun they modified. The Germanic distinction between strong and weak, or indefinite and definite inflection,

1222-423: The modern zond , mirroring strong class 3. Windrow A windrow is a row of cut (mown) hay or small grain crop. It is allowed to dry before being baled , combined , or rolled. For hay, the windrow is often formed by a hay rake , which rakes hay that has been cut by a mowing machine or by scythe into a row, or it may naturally form as the hay is mown. For small grain crops which are to be harvested,

1269-469: The modern period in Limburgish, and the distinction between /ol/ and /al/ was preserved, being reflected as ów and aa respectively. Phonological changes that occurred during Middle Dutch: Middle Dutch was not a single homogeneous language. The language differed by area, with different areas having a different pronunciation and often using different vocabulary. The dialect areas were affected by political boundaries. The sphere of political influence of

1316-472: The neighbouring areas. Middle Dutch has four major dialects groups: Flemish, Brabantic and Hollandic are known as West Franconian, while Limburgic is known as East Franconian (not to be confused with the High German dialect East Franconian ). In a finer classification there are: Brabantian was spoken primarily in the Duchy of Brabant . It was an influential dialect during most of the Middle Ages, during

1363-428: The past participle. In classes 6 and 7, there was no distinction between the two different vowels of the past tense. In classes 4 and 5, the difference was primarily one of length, since ā and â were not distinguished in most dialects. The difference between ê and ē , and between ô and ō , found in classes 1 and 2, was a bit more robust, but also eventually waned in the development to modern Dutch. Consequently,

1410-486: The rate of surface runoff . The berms either reduce the velocity of the water , or direct water to areas that are not susceptible to erosion, thereby reducing the adverse effects of running water on exposed topsoil . Following the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, the construction of berms designed to prevent oil from reaching the fragile Louisiana wetlands (which would result in massive erosion)

1457-411: The second- and third-person singular present indicative forms, instead of e . This is a remnant of older i-mutation in these forms. Umlaut is also sometimes found in the past subjunctive in the east. Middle Dutch retained weak verbs as the only productive class of verbs. While Old Dutch still had two different classes of weak verbs (and remnants of a third), this distinction was lost in Middle Dutch with

1504-483: The so-called "Brabantian expansion" in which the influence of Brabant was extended outwards into other areas. Compared to the other dialects, Brabantian was a kind of "middle ground" between the coastal areas on one hand, and the Rhineland and Limburg on the other. Brabantian Middle Dutch has the following characteristics compared to other dialects: Flemish, consisting today of West and East Flemish and Zeelandic ,

1551-479: The soil from which the berm is constructed. Walls constructed in this manner are an obstacle to vehicles , including most armoured fighting vehicles but are easily crossed by infantry . Because of the ease of construction , such walls can be made hundreds or thousands of kilometres long. A prominent example of such a berm is the 2,700 km (1,700 mi) Moroccan Western Sahara Wall . Berms are also used to control soil erosion and sedimentation by reducing

1598-533: The subjunctive became distinguished from the indicative only in the singular but was identical to it in the plural, and also in the past tense of weak verbs. That led to a gradual decline in the use of the subjunctive, and it has been all but lost entirely in modern Dutch. The seven classes of strong verb common to the Germanic languages were retained. The four principal parts were the present tense, first- and third-person singular past tense, remaining past tense, and

1645-406: The three main inflectional classes. Verbs were inflected in present and past tense, and in three moods: indicative, subjunctive and imperative. The weakening of unstressed vowels affected the distinction between the indicative and subjunctive moods, which had largely been determined by the vowel of the inflectional suffix in Old Dutch. In Middle Dutch, with all unstressed vowels merging into one,

1692-461: The trench). Security berms are common around military and nuclear facilities. An example is the berm proposed for Vermont Yankee nuclear power plant in Vermont. At Baylor Ballpark , a baseball stadium on the campus of Baylor University , a berm is constructed down the right field line. The berm replaces bleachers, and general admission tickets are sold for fans who wish to sit on the grass or watch

1739-435: The underlying phonemic value. However, by and large, spelling was phonetic, which is logical as people usually read texts out loud. Modern dictionaries tend to represent words in a normalised spelling to form a compromise between the variable spellings on one hand and to represent the sounds of the language consistently. Thus, normalised spellings attempt to be a general or "average" spelling but still being accurate and true to

1786-608: The vowels merged with the "soft-long" vowels during the early modern Dutch period. The vowels /eː/ , /œː/ and /oː/ , termed "soft-long" and denoted with a macron ē ō , developed through the lengthening of Old Dutch short vowels in open syllables, but also frequently before /r/ . They were simple monophthongs in all Middle Dutch dialects, with the exception of western Flanders where /eː/ later developed into /ei̯/ . They might have been close-mid but also perhaps open-mid [ɛː] , [œː] and [ɔː] , as in modern Limburgish. There were two open vowels, with "sharp-long" â developed from

1833-465: The weakening of unstressed syllables. The past tense was formed with a suffix -ed- , which generally lost its e through syncope and thus came to be directly attached to the preceding stem. This triggered voicing assimilation, so that t appeared whenever the preceding stem ended in a voiceless consonant. This phenomenon remains in modern Dutch. Unsyncopated forms, which retain the fuller suffix -ed- , are sometimes found, especially with stems ending in

1880-400: The windrow is formed by a swather which both cuts the crop and forms the windrow. By analogy, the term may also be applied to a row of any other material such as snow, earth or materials for collection. Windrow composting is a large scale vermicomposting system where garden and other biodegradable waste is shredded, mixed and windrowed for composting. This agriculture article is

1927-585: Was a general distinction between strong and weak nouns. Eventually even these started to become confused, with the strong and weak endings slowly beginning to merge into a single declension class by the beginning of the modern Dutch period. The strong nouns generally originated from the Old Dutch a-stem, i-stem and u-stem inflections. They mostly had a nominative singular with no ending, and a nominative plural in -e or, for some neuter nouns, with no ending. Most strong nouns were masculine or neuter. Feminines in this class were former i-stems, and could lack an ending in

1974-399: Was fairly minimal in Middle Dutch, appearing only in the masculine and neuter nominative singular. These forms received an -e ending when a definite word (demonstrative, article) preceded, and had no ending otherwise. Adjectives were uninflected when connected through a copula. Thus, even for feminine nouns, no ending appeared: die vrouwe is goet "the lady is good". Some adjectives, namely

2021-471: Was not clearly tied to one political area, instead being divided among various areas, including the Duchy of Limburg (which was south of modern Limburg). It was also the most divergent of the dialects. Kleverlandish ("Kleverlands") was spoken around the area of the Duchy of Cleves , around the Lower Rhine . It represented a transitional dialect between Limburgish and Middle Low German . Middle Dutch

In coastal geography, a berm is a bank of sand or gravel ridge parallel to the shoreline and a few tens of centimetres high, created by wave action throwing material beyond the average level of the sea. Earth

2115-527: Was reflected in the spelling, and clitic pronouns and articles were frequently joined to the preceding or following word. Scribes wrote in their own dialect, and their spelling reflected the pronunciation of that particular scribe or of some prestige dialect by which the scribe was influenced. The modern Dutch word maagd (" maiden ") for example was sometimes written as maghet or maegt , but also meget , magt , maget , magd , and mecht . Some spellings, such as magd , reflect an early tendency to write

2162-490: Was spoken in the County of Flanders , northern parts of the County of Artois and areas around the towns of Calais and Boulogne-sur-Mer . Though due to their intermediary position between West Flemish and Brabantian , the East Flemish dialects have also been grouped with the latter. Flemish had been influential during the earlier Middle Ages (the "Flemish expansion") but lost prestige to the neighbouring Brabantian in

2209-515: Was written in the Latin alphabet , which was not designed for writing Middle Dutch so different scribes used different methods of representing the sounds of their language in writing. The traditions of neighbouring scribes and their languages led to a multitude of ways to write Middle Dutch. Consequently, spelling was not standardised but was highly variable and could differ by both time and place as various "trends" in spelling waxed and waned. Furthermore,
