Acqua Alta
(, ; ) is the term used in Veneto, Italy for the exceptional tide peaks that occur periodically in the northern Adriatic Sea. The peaks reach their maximum in the Venetian Lagoon, where they cause partial flooding of Venice and Chioggia; flooding also occurs elsewhere around the northern Adriatic, for instance at Grado and Trieste, but much less often and to a lesser degree. The phenomenon occurs mainly between autumn and spring, when the astronomical tides are reinforced by the prevailing seasonal winds that hamper the usual reflux. The main winds involved are the sirocco, which blows northbound along the Adriatic Sea, and the bora, which has a specific local effect due to the shape and location of the Venetian Lagoon. Causes Precise scientific parameters define the phenomenon called ''acqua alta'', the most significant of which (i.e., the deviation in amplitude from a base measurement of "standard" tides) is measured by the hydrographic station located nearby the Ba ...

Piazza San Marco
Piazza San Marco (; vec, Piasa San Marco), often known in English as St Mark's Square, is the principal public square of Venice, Italy, where it is generally known just as ''la Piazza'' ("the Square"). All other urban spaces in the city (except the Piazzetta and the Piazzale Roma) are called ''campi'' ("fields"). The Piazzetta ("little Piazza/Square") is an extension of the Piazza towards San Marco basin in its southeast corner (see plan). The two spaces together form the social, religious and political centre of Venice and are commonly considered together. This article relates to both of them. A remark usually attributed (though without proof) to Napoleon calls the Piazza San Marco "the drawing room of Europe". Description The square is dominated at its eastern end by St Mark's Basilica. It is described here by a perambulation starting from the west front of the church (facing the length of the piazza) and proceeding to the right. The church is described in the articl ...

Subsidence
Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement. Processes that lead to subsidence include dissolution of underlying carbonate rock by groundwater; gradual compaction of sediments; withdrawal of fluid lava from beneath a solidified crust of rock; mining; pumping of subsurface fluids, such as groundwater or petroleum; or warping of the Earth's crust by tectonic forces. Subsidence resulting from tectonic deformation of the crust is known as tectonic subsidence and can create accommodation for sediments to accumulate and eventually lithify into sedimentary rock. Ground subsidence is of global concern to geologists, geotechnical engineers, surveyors, engineers, urban planners, landowners, and the public in general.National Research Council, 1991.

Brenta (river)
The Brenta is an Italian river that runs from Trentino to the Adriatic Sea just south of the Venetian lagoon in the Veneto region, in the north-east of Italy. During the Roman era, it was called Medoacus (Ancient Greek: ''Mediochos'', ''Μηδειοχος'') and near Padua it divided in two branches, Medoacus Maior (Greater Medoacus) and Medoacus Minor (Lesser Medoacus). The river changed its course in the early Middle Ages, and its former bed through Padua was occupied by the Bacchiglione. It is long and was first channelled in the 16th century when a long canal was built from the village of Stra to the Adriatic Sea, bypassing the Venetian lagoon. A branch of the Brenta, named '' Naviglio del Brenta'', was left to connect directly Venice and Padua (which was a kind of second capital of the Venice Republic). It runs through Stra, Fiesso d'Artico, Dolo, Mira, Oriago and Malcontenta to Fusina (which is part of the comune of Venice). Starting in the 16th century, many lar ...

Porto Marghera
Marghera is a ''municipalità'' (borough) of the ''comune'' of Venice, Italy. It includes the industrial area known as Porto Marghera (English: Marghera Port) or Venezia Porto Marghera. Etymology The name Marghera is said in popular myth to come from Venetian dialectal "Mar gh' era," meaning "There was the sea"; the original form, however, was Mergaria, whose origin is unclear. History At the beginning of the 20th century Venice's existing port at Bacino San Marco was incapable of servicing large modern ships. A new port was constructed at the western end of Venice at Stazione Marittima, but it became clear that if industry was developed in its immediate vicinity it would negatively impact on the historical city and tourism. As a result, by 1917 – during the First World War – the Italian government decided to develop an industrial zone and state-of-the-art port at Marghera on the mainland, opposite Venice and near the town of Mestre. A major backer of the scheme was Count Gius ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bora (wind)
The bora is a northerly to north-easterly katabatic wind in areas near the Adriatic Sea. Similar nomenclature is used for north-eastern winds in other littoral areas of eastern Mediterranean and Black Sea basins. Name It is known in Greek as (''mpóra'', pronounced ''bora'') and Italian as . In English, the name ''bora'' is used. The Serbo-Croatian name and Slovene are not etymologically related to ''bora''; they derive from Common Slavic ''burja'' 'storm' (from the verb ''*burĭti''), and the meaning 'bora' developed later. The same root as ''bora'' is found in the name of the Greek mythological figure of Boreas (Βορέας), and the Modern Greek word for the north wind . Historical linguists speculate that the name may derive from a Proto-Indo-European root *''gworhx-'' 'mountain', which gave rise to Slavic ''gora'' and Sanskrit ''giri-'', both 'mountain'. Features The changeable bora can often be felt all over Adriatic Croatia, Montenegrin Littoral, the Slov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Equinox
A solar equinox is a moment in time when the Sun crosses the Earth's equator, which is to say, appears directly above the equator, rather than north or south of the equator. On the day of the equinox, the Sun appears to rise "due east" and set "due west". This occurs twice each year, around 20 March and 23 September. More precisely, an equinox is traditionally defined as the time when the plane of Earth's equator passes through the geometric center of the Sun's disk. Equivalently, this is the moment when Earth's rotation axis is directly perpendicular to the Sun-Earth line, tilting neither toward nor away from the Sun. In modern times, since the Moon (and to a lesser extent the planets) causes Earth's orbit to vary slightly from a perfect ellipse, the equinox is officially defined by the Sun's more regular ecliptic longitude rather than by its declination. The instants of the equinoxes are currently defined to be when the apparent geocentric longitude of the Sun is 0° a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full Moon
The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic longitudes of the Sun and Moon differ by 180°). This means that the lunar hemisphere facing Earth—the near side—is completely sunlit and appears as an approximately circular disk. The full moon occurs roughly once a month. The time interval between a full moon and the next repetition of the same phase, a synodic month, averages about 29.53 days. Therefore, in those lunar calendars in which each month begins on the day of the new moon, the full moon falls on either the 14th or 15th day of the lunar month. Because a calendar month consists of a whole number of days, a month in a lunar calendar may be either 29 or 30 days long. Characteristics A full moon is often thought of as an event of a full night's duration, although its phase seen from Earth continuously waxes or wanes, and is full ...

New Moon
In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude. At this phase, the lunar disk is not visible to the naked eye, except when it is silhouetted against the Sun during a solar eclipse. The original meaning of the term 'new moon', which is still sometimes used in calendrical, non-astronomical contexts, is the first visible crescent of the Moon after conjunction with the Sun. This thin waxing crescent is briefly and faintly visible as the Moon gets lower in the western sky after sunset. The precise time and even the date of the appearance of the new moon by this definition will be influenced by the geographical location of the observer. The first crescent marks the beginning of the month in the Islamic calendar and in some lunisolar calendars such as the Hebrew calendar. In the Chinese calendar, the beginning of the month is marked by the last visible crescent of a waning Moon. The astronomical new moon occur ...

Perigee
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, the apsides of the Earth are called the aphelion and perihelion. General description There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ''ap-'', ''apo-'' (), or ''peri-'' (), each referring to the farthest and closest point to the primary body the affixing necessary suffix that describes the primary body in the orbit. In this case, the suffix for Earth is ''-gee'', so the apsides' names are ''apogee'' and ''perigee''. For the Sun, its suffix is ''-helion'', so the names are ''aphelion'' and ''perihelion''. According to Newton's laws of motion, all periodic orbits are ellipses. The barycenter of the two bodies may lie well within the bigger body—e.g., the Earth–Moon barycenter is about 75% of the way from Earth's center to its surface. If, compared to the larger mass, the smaller mass is negligible (e.g. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seiche
A seiche ( ) is a standing wave in an enclosed or partially enclosed body of water. Seiches and seiche-related phenomena have been observed on lakes, reservoirs, swimming pools, bays, harbors, caves and seas. The key requirement for formation of a seiche is that the body of water be at least partially bounded, allowing the formation of the standing wave. The term was promoted by the Swiss hydrologist François-Alphonse Forel in 1890, who was the first to make scientific observations of the effect in Lake Geneva. The word had apparently long been used in the region to describe oscillations in alpine lakes. According to Wilson (1972), this Swiss French dialect word comes from the Latin word meaning "dry", i.e., as the water recedes, the beach dries. The French word or (dry) descends from the Latin. Seiches in harbours can be caused by ''long period'' or '' infragravity waves'', which are due to subharmonic nonlinear wave interaction with the wind waves, having periods longer th ...
