Pazinčica
The Pazinčica or Pazinski potok (, Fojba), locally Potȍk or Patȍk, is a river in the central part of the Istrian peninsula, Croatia. It flows above ground before entering its ponor, the , continuing as a subterranean river. It is the longest such river in Istria. Course From its source near Borut to its ponor in Pazin, it has only a few constant tributaries: the Brestovica, Toplica, Lipa, Rakov potok and Frnežar. From its spring to its ponor, the elevation difference is a mere to , supported by layers of flysch. Its final section is relatively complex, featuring stone blocks called ''kruge'', lakes called ''puče'' and two larger waterfalls ( and Pazinski krov). In its geological history, it once drained directly into the Adriatic through what is now the Lim valley. The course of the river was then diverted from a northward to a southward direction where, at the contact between flysch and limestone, a ponor was formed. Flow tracing has shown that the river drains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lim (Croatia)
The Lim bay (, ) and valley is a peculiar geographic feature found near Rovinj-Rovigno and Vrsar-Orsera on the western coast of Istria, south of Poreč-Parenzo, Croatia. The name comes from the Latin for "limit", referring to the landform's position at the border of two Roman provinces: Dalmatia and Italia. Geography The Lim valley () is the 35 km long valley of the river Pazinčica, which transforms into the Lim bay (), a 10 kilometer long estuary. The Croats sometimes also call it ("Lim channel"), due to its narrow width. The estuary is sometimes called a fjord, although it is not in fact a fjord but a ria, because it was not carved by a glacier but by the river eroding the ground on its way to the Adriatic Sea, when the sea level was lower. Owing to its geological history, this estuary is one of the most instructive examples of limestone hydrological development. The Lim stream used to flow through the valley but dried up regularly, and was really only present a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adriatic
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkans, Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The prevailing currents flow counterclockwise from the Strait of Otranto. Tidal movements in the Adriatic are slight, although acqua alta, larger amplitudes occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because it collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures ...

Borut, Croatia
Borut () is a village in Istria, Croatia. The name Borut or Borutto is the common name for several small villages and hamlets: Budaki, Buzići, Čuleti, Dausi, Grdinići, Grgurići, Moloni, Orlovići, Poljanice and Sandalji. When Istria was part of the Kingdom of Italy, the village was called Borutto di Bogliuno which was located in the Province of Pola. On top of the largest hill in Borut is the Church of St Michael the Archangel built in the 13th century and enlarged in 1787. It has a Romanesque semi-circular sanctuary and a Venetian style high altar. A small distance from the train station is the Church of the Holy Spirit reconstructed in 1560 by Vid Vitulic as indicated by the Glagolitic inscription above the entrance door. There is evidence of human settlement in and around Borut by the Histri, an ancient Venetic tribe and an Indo-European people. The area was part of the Roman Empire for centuries and subsequently the Byzantine Empire. During the 13th century, the villag ...

Flysch
Flysch () is a sequence of sedimentary rock layers that progress from deep-water and turbidity flow deposits to shallow-water shales and sandstones. It is deposited when a deep basin forms rapidly on the continental side of a mountain building episode. Examples are found near the North American Cordillera, the Alps, the Pyrenees and the Carpathians. Sedimentological properties Flysch consists of repeated sedimentary cycles with upwards fining of the sediments. There are sometimes coarse conglomerates or breccias at the bottom of each cycle, which gradually evolve upwards into sandstone and shale/mudstone. Flysch typically consists of a sequence of shales rhythmically interbedded with thin, hard, graywacke-like sandstones. Typically the shales do not contain many fossils, while the coarser sandstones often have fractions of micas and glauconite. Tectonics In a continental collision, a subducting tectonic plate pushes on the plate above it, making the rock fold, often t ...

Drainage Basins Of The Adriatic Sea
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley Civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Simple infrastructure such as open drains, pipes, and berms are still common. In modern times, more complex structures involving substantial earthworks and new technologies have been common as well. Geotextiles New storm water drainage sys ...

Footbridge
A footbridge (also a pedestrian bridge, pedestrian overpass, or pedestrian overcrossing) is a bridge designed solely for pedestrians.''Oxford English Dictionary'' While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic. For rural communities in the developing world, a footbridge may be a community's only access to medical clinics, schools, businesses and markets. Simple suspension bridge designs have been developed to be Sustainability, sustainable and easily constructed in such areas using only local materials and labor. An enclosed footbridge between t ...

Raša (river)
The Raša (, Italian: ) in Croatian Istria is a major river of Croatia's Istria County. It is long, and its basin covers an area of . Its mouth is in the long ria of Raša Bay (, formerly ), which is a drowned river valley scoured out when world sea levels fell, then drowned by the rising waters of the post-glacial era. The Raša rises in springs near Pićan and flows south through a steep-sided valley before opening into the head of the Adriatic Sea. The river, although short in length, has an ancient history as a border. Border river By Roman times, the Arsia, as it was called in Latin, constituted the border between the Histri, who lived west of its banks, and the Liburni on the coast to the east, with the Iapydes in the upcountry valley behind them. After the Romans conquered the fierce and piratical Histri in 177 BC, the Arsia formed the '' limes'' of Roman territory in coastal Istria for a generation, until the gap between the Arsia and the northernmost Roman outposts ...

Flow Tracer
A flow tracer is any fluid property used to track the flow velocity (i.e., flow magnitude and direction) and circulation patterns. Tracers can be chemical properties, such as radioactive material, or chemical compounds, physical properties, such as density, temperature, salinity, or dyes, and can be natural or artificially induced. Flow tracers are used in many fields, such as physics, hydrology, limnology, oceanography, environmental studies and atmospheric studies. Conservative tracers remain constant following fluid parcels, whereas reactive tracers (such as compounds undergoing a mutual chemical reaction) grow or decay with time. ''Active tracers'' dynamically alter the flow of the fluid by changing fluid properties which appear in the equation of motion such as density or viscosity, while ''passive tracers'' have no influence on flow. Uses in oceanography Ocean tracers are used to deduce small scale flow patterns, large-scale ocean circulation, water mass formation a ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...
