The Zlatni Rat , often referred to as the Golden Cape or Golden Horn (translated from the local Chakavian dialect ), is a spit of land located about 2 kilometres (1 mile) west from the harbour town of Bol on the southern coast of the Croatian island of Brač , in the region of Dalmatia . It extends southward into the Hvar Channel , a body of water in the Adriatic Sea between the islands of Brač and Hvar , which is home to strong currents. The landform itself is mostly composed of a white pebble beach, with a Mediterranean pine grove taking up the remainder.
42-524: Zlatni Rat has been regularly listed as one of the top beaches in Europe and in the World. Its distinctive shape can be seen in many travel brochures, which made it one of the symbols of Croatian tourism. In 2008 Red Bull organized Red Bull Golden Jump , a unique kiteboarding competition in jumping/flying over the beach. The beaches on either side of the spit, measured in 2015 east side was 377 metres (1,237 ft) and
84-467: A day or may last several days. While passing over the Mediterranean Sea, the sirocco picks up moisture; this results in rainfall in the southern part of Italy , known locally as "blood rain" due to the red sand mixed with the falling rain. Sirocco is commonly perceived as causing unease and an irritable mood in people. In addition, many people attribute health problems to the wind, either because of
126-529: 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. Precise scientific parameters define
168-685: A rising tide, the sirocco can cause the acqua alta phenomenon in the Venetian Lagoon . This wind also has an impact on fishing. For example, the anchovies caught in the Gulf of Trieste , near Barcola , which are in great demand as a delicacy, are caught only in a sirocco. In cold winds, like the bora , the fish disappear into the Adriatic . Acqua alta An acqua alta ( / ˌ æ k w ə ˈ æ l t ə / , Italian: [ˈakkwa ˈalta] ; lit. ' high water ' )
210-573: A sequence of whistles whose number increases with the expected tide level (according to a published equivalence table). While not radically innovative, the new system communicates in greater detail the extent of the expected flooding to the population. The previous system, still used in the rest of the Venetian lagoon, only provides three levels of warning: the signal is sounded once for a tide above 110 cm., twice for tidal forecasts above 140 cm. and thrice for those above 160 cm. The new system
252-436: A study that suggests the following initiatives may have had an irreversible and catastrophic impact on the city's capacity to withstand acque alte in the future: The flooding caused by the acqua alta is not uniform throughout the city of Venice because of several factors, such as the varying altitude of each zone above sea level, its distance from a channel, the relative heights of the sidewalks or pavements ( fondamenta ),
294-540: Is also charged with continuously keeping the population informed. Renamed Tide Monitoring and Forecast Center in 1980, the service has absorbed the record-keeping functions of the Hydrographic Office. The first record of a large flood in the Venetian lagoon dates back to the so-called Rotta della Cucca , reported by Paul the Deacon as having occurred on October 17, 589. According to Paul, all rivers with mouths in
336-450: Is an exceptional tide peak that occurs periodically in the northern Adriatic Sea . The term is applied to such tides in the Italian region of Veneto . 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
378-413: Is built was created by filling large parts of the lagoon where smaller islands just above sea level previously lay. These islands, called barene , acted as natural sponges (or "expansion tanks") when high tides occurred, absorbing a significant portion of the excess water. Second, a navigable channel was carved through the lagoon to allow oil tankers to reach the piers. This "Oil Channel" physically linked
420-615: Is comparable to naturally occurring (yet independent) astronomical tides, the two effects overlap and reinforce each other. The combined effects are more significant at the perigees , which correspond to new moons , full moons and equinoxes . Should meteorological conditions (such as a strong scirocco wind blowing north along the major axis of the Adriatic basin) hamper the natural outflow of excess tidal water, high waters of greater magnitude can be expected in Venice. The particular shape of
462-423: Is considered to have begun in 1872, although some researchers suggest pushing this date to 1867, when an exceptional event (153 cm above sea level) was measured. However, because the first modern marigraph for regular tide monitoring was installed in Venice only in 1871, most documentation on the subject adopts the following year as the golden standard. The Venetian Institute for Science, Literature and Arts

#1732852540401504-580: The Doge 's residence was moved to Rialto . Local chroniclers report that in 1240 "the water (that) flooded the streets (was) higher than a man". Other events are recorded to have occurred in 1268, 1280, 1282, and on December 20, 1283, which was probably an abnormally significant event, since a chronicle reported that Venice was "saved by a miracle". Chroniclers report that high tides occurred in 1286, 1297, and 1314; on February 15, 1340; on February 25, 1341; on January 18, 1386; and on May 31 and August 10, 1410. In
546-549: The subsidence , i.e. the natural sinking of the soil level, to which the lagoon is subject, and eustasy , i.e. the progressive rise of sea levels. While these phenomena would occur independently of human activity, their effects have increased because of inhabitation: the use of lagoonal water by the industries in Porto Marghera (now ceased) sped up subsidence, while global warming has been linked to increased eustasy. Venice's "Tide Monitoring and Forecast Center" evaluates that
588-471: The 15th century, high tides were recorded in 1419 and 1423, on May 11, 1428, and on October 10, 1430, as well as in 1444 and 1445. On November 10, 1442, the water is reported to have risen "four feet above the usual". High waters were recorded on May 29, 1511; in 1517; on October 16, 1521; on October 3 and, again, on December 20, 1535. Local chronicles also attest to floods occurring in 1543; on November 21, 1550; on October 12, 1559; and in 1599. The year 1600
630-593: The Arabian or Sahara deserts. The hotter, drier continental air mixes with the cooler, wetter air of the maritime cyclone , and the counter-clockwise circulation of the low propels the mixed air across the southern coasts of Europe. The sirocco causes dusty dry conditions along the northern coast of Africa, storms in the Mediterranean Sea, and warm wet weather in Southern Europe. The sirocco does not affect other parts of Europe. The sirocco's duration may be as short as half
672-577: The City of Venice is fed information via a network of hydrographic stations, located in both the lagoon and the Adriatic Sea (on a scientific platform belonging to the Italian National Research Committee, CNR). The centre's unique expertise on the phenomenon enables it to produce forecasts of remarkable accuracy, usually for the following 48 hours (longer forecasts are also issued, but tend to be less reliable, as discussed above), by analysing
714-573: The East, aš-šarq . Various names for this wind in other languages include: The Roman poet Horace refers to the sirocco at Trevico in Apulia as "Atabulus" (a Messapic word) in his account of his journey to Brundisium in 37 BC. Siroccos arise from warm, dry, tropical air masses that are pulled northward by low-pressure cells moving eastward across the Mediterranean Sea , with the wind originating in
756-580: The Lodge after the 1902 fall of the Campanile and for subsidence, estimates concluded that the tide may have been as high as 254 cm above today's standard sea level. In the 18th century, records became more abundant and precise, reporting acque alte on December 21, 1727; New Year's Eve, 1738; October 7, 1729; November 5 and 28, 1742; October 31, 1746; November 4, 1748; October 31, 1749; October 9, 1750; Christmas Eve, 1792; and on Christmas Day, 1794. Finally, in
798-423: The Venetian lagoon, the subsidence which has been affecting the soil in the coastal area, and the peculiar urban configuration all magnify the impact of the high waters on city dwellers and on the buildings. Furthermore, the northbound winds called bora and sirocco often blow directly towards the harbors that connect the lagoon to the Adriatic Sea, significantly slowing down (and, at times, completing blocking)
840-488: The basin's minor axis. The principal oscillation, which has a period of 21 hours and 30 minutes and an amplitude around 0.5 meters at the axis' extremities, supplements the natural tidal cycle, so that the Adriatic Sea has much more extreme tidal events than the rest of the Mediterranean. A secondary oscillation is also present, with an average period of 12 hours and 11 minutes. Because the timeframe of both oscillations

During extreme weather with stormy winds and waves, the top can shift from one side to the other in a matter of hours. The promontory is protected as a geomorphological phenomenon. The sea is normally warmer on

#1732852540401924-554: The beach, and several coves to the west of the main beach, are traditionally clothing-optional . Jugo Sirocco ( / s ɪ ˈ r ɒ k oʊ / sih- RO -koh ) or scirocco is a Mediterranean wind that comes from the Sahara and can reach hurricane speeds in North Africa and Southern Europe , especially during the summer season. Sirocco derives from šurūq ( Arabic : شروق ), verbal noun of šaraqa , related to
966-462: The city has lost 23 cm in its elevation since 1897, the year of reference, 12 of which are attributable to natural causes (9 because of eustasy, 3 because of subsidence), 13 are due to the additional subsidence caused by human activity, while the "elastic recovery" of the soil has allowed the city to "gain back" 2 cm. The long and narrow rectangular shape of the Adriatic Sea is the source of an oscillating water motion (called seiche ) along
1008-407: The city. The study provided Venetians with the following reference guide: To assist pedestrian circulation during floods, the city installs a network of gangways (wide wooden planks on iron supports) on the main urban paths. This gangway system is generally set at 120 cm above the conventional sea level, and can flood as well when higher tides occur. The Tide Monitoring and Forecast Centre of

These are the highest water levels documented by the Tide Monitoring and Forecast Centre of Venice : In Kozue Amano 's utopian science fantasy manga series Aria and its anime adaptation , acqua alta is a phenomenon that happens in
1092-463: The effects of "exceptional high waters" (but not those of lesser, yet detrimental, tidal events) by completing the installation of 79 separate 300-ton flaps hinged on the seabed between the lagoon and the Adriatic sea. While normally fully submerged and invisible, the flaps can be raised preemptively to create a temporary barrier, which is expected to protect the city from exceptional acqua alta . Regular scientific record-keeping of lagoonal water levels
1134-511: The heat and dust brought from African coastal regions, or because of the cool dampness further north in Europe. The dust in the sirocco winds can cause abrasion in mechanical devices and penetrate buildings. Sirocco winds with speeds of up to 100 km/h (62 mph; 54 kn) are most common during autumn and spring. They reach a peak in March and in November when it is very hot. When combined with
1176-480: The lands on Mars referred to as Neo Venezia. Donna Leon refers to acqua alta in multiple books in her Commissario Guido Brunetti Mystery Series, set in and around Venice . For example: In the popular manga and anime One Piece by Eiichiro Oda , Season 8 is set in Water 7, a city inspired by Venice. This season introduces the phenomenon of Aqua Laguna, an annual event in which rising water levels completely floods
1218-430: The meteorological and hydrographic data available. Forecasts are then announced to the population via the centre's website and dedicated phone lines, through local newspapers, on electronic displays, and at some stops of the vaporetti (public transport). When an acqua alta event is forecast, owners of commercial and residential property that is likely to be affected are contacted by phone (a free service provided by
1260-436: The municipality) or SMS . "Very intense" events warrant alerting the whole population, which is accomplished by sounding a dedicated system of sirens located throughout the city. On December 7, 2007, the alert system was modified (in Venice alone) to signal the magnitude of expected "very intense" tidal events to the population: sirens sound a first "await instructions" whistle to catch the population's attention, then produce
1302-603: The northern Adriatic, from the Tagliamento to the Po , overflowed at the same time, completely modifying the hydro-geologic equilibrium of the lagoon. The first documented description of acqua alta in Venice concerns the year 782 and is followed by other documented events in 840, 885, and 1102. In 1110 the water, following a violent sea storm (or, possibly, a seaquake and its subsequent tsunami ), completely destroyed Metamauco (ancient name for Malamocco), Venice's political centre before

1344-399: The outflow of water from the lagoon toward the sea. When this occurs, the ebb is prevented inside the lagoon, so that the following high tide overlaps with the previous one, in a perverse self-supporting cycle. The creation of the industrial area of Porto Marghera , which lies immediately behind Venice, amplified the effects of high waters for two reasons: first, the land upon which the area
1386-471: 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 Basilica di Santa Maria della Salute . Supernormal tidal events can be categorized as: Generally speaking, tide levels largely depend on three contributing factors: Two further contributing natural factors are
1428-485: The presence of full parapets (which act as dams) along the proximate channel, and the layout of the sewer and water drainage network (which acts as a channel for the flooding, as it is directly connected with the lagoon). These factors account for the severity and spread of a supernormal tidal phenomenon; as a city-commissioned study showed, a tide up to 90 cm above sea level leaves Venice virtually unaffected, while 50 cm of additional water affects more than half of
1470-463: The sea to the coastal line, running through the harbor in Malamocco and crossing the lagoon for its entire width. This direct connection to the sea, which was obviously non-existent at the time of Venice's foundation, has subjected the city to more severe high tides. Porto Marghera and its facilities are not the only human-made contributors to higher tides. Rather, the municipality of Venice has published

A reliable afternoon westerly wind known as a Maestral has made the beach a destination for windsurfers . The pine tree grove that borders the beach is home to the remnants of a Roman villa rustica , which included a swimming pool. The westernmost edge of

[Sansovino's] Lodge", which is the monumental entrance to the Campanile di San Marco . A similar level was reached during the exceptional flood of November 4, 1966, which allowed scholars in the late 1960s to recreate a likely scenario for the 1686 flood. After accounting for the rebuilding of
1596-507: The west side was 479 metres (1,572 ft) long, but the exact shape and length of the landform varies with regard to changes in tide, current, waves and wind. The spit points directly south. The farthest end, which is usually turned slightly toward the east, will often shift to the west in certain weather conditions, esp. a strong south-easterly wind known in Croatia as the Jugo . Changes in the shape of

The Institute ceased to exercise its monitoring and record-keeping functions in 1908, when the task, along with records and instruments, was passed to the Hydrographic Office of Venice . After the unprecedented acqua alta of 1966 , the city set up a dedicated service to analyse data, monitor fluctuations, and forecast high tides, which
1722-429: Was characterized by a high frequency of events, with floods on December 8 as well as December 18 and 19. The latter event was probably remarkable, since there are also records of very violent sea storms that, having "broken indeed the shores in several places, entered the towns of Lido Maggiore, Tre Porti, Malamocco, Chiozza, et cetera". Another noteworthy acqua alta took place on November 5, 1686. Several chronicles of
