Ombla
The Ombla is a short river in Croatia, northeast of Dubrovnik. Its course is approximately long, and it empties into the Rijeka Dubrovačka, ria formed by the Adriatic Sea near Komolac in Dubrovnik-Neretva County. Rijeka Dubrovačka is actually a ria, a flooded river valley formed through changes in sea surface elevation on a geologic time scale. The river rises as a karst spring fed by groundwater replenished by Trebišnjica, which is an influent stream flowing in Popovo Polje, in the immediate hinterland of the Ombla. The elevation difference between the river's source and its mouth is just over . The average discharge of the river is per second. The drainage basin of the Ombla encompasses and, besides the short surface course, includes only groundwater flow. The Ombla is used as a source of drinking water for Dubrovnik's water supply network, and construction of a hydroelectric power plant has been planned for the past two decades. , the plans entail construction of a subsu ...

Trebišnjica
The Trebišnjica ( sr-cyrl, Требишњица) is a river in Bosnia and Herzegovina. It used to be a sinking river, long above the ground. With a total length of above and under the ground, it is one of the longest sinking rivers in the world. In classical antiquity, the river was known as the Arion, rising and sinking through its course before resurfacing at various places from the Neretva to the coast. Sources The Trebišnjica river originate near town of Bileća. The source of the river is a system of strong karstic wellsprings distributed in two principal aquifer zones, geographically and hydrologically distinct albeit in relatively close proximity to each other. In both zones group of wellsprings raises from the underground, consisting of a number of large, abundant founts each. The first, at the head of the river and at the outskirts of Bileća town, is the Trebišnjica wellsprings group, consisting of three large wellsprings, with Dejanova Pećina as primer outflow ...

Losing Stream
A losing stream, disappearing stream, influent stream or sinking river is a stream or river that loses water as it flows downstream. The water infiltrates into the ground recharging the local groundwater, because the water table is below the bottom of the stream channel. This is the opposite of a more common ''gaining stream'' (or ''effluent stream'') which increases in water volume farther downstream as it gains water from the local aquifer. Losing streams are common in arid areas due to the climate which results in huge amounts of water evaporating from the river generally towards the mouth. Losing streams are also common in regions of karst topography where the streamwater may be completely captured by a cavern system, becoming a subterranean river. Examples There are many natural examples of subterranean rivers including: Bosnia and Herzegovina * Unac; Mušnica-Trebišnjica- Krupa/Ombla (Trebišnjica is considered to be one of the largest sinking rivers in the world; ...

Adriatic Sea
The Adriatic Sea () is a body of water separating the Italian Peninsula from the 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 the Croatian part of 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 Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasi ...

Komolac
Komolac is one of two city districts Dubrovnik, Croatia, which are located in the region of Rijeka Dubrovačka, Rijeka Dubrovacka. It includes the populated places of Komolac, Rozat, Prijevor and Sumet. Komolac is known for its waterfall of the shortest river in the world, the Ombla. The falls have been supplying the city of Dubrovnik with drinking water since the time of the Republic of Dubrovnik, more precisely since 1438, when the first Dubrovnik water supply system was put into operation. Among other sights, it is worth mentioning the Church of The Holy Spirit, the Church of the Annunciation, the Church of St. Tripun, the House Gundulic, the summer House Bizzaro - Facenda, Summer House Pero Kolic and Summer House Sokorcevic - Skala, which are entered in the Registar of Cultural Heritage of The Republic of Croatia. A monument to the fallen veterans in Komolac, unveiled on May 26, 2017, on the occasion of the 25th anniversary of the liberation of Dubrovnik, is also located in Komol ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Massif
In geology, a massif ( or ) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure. In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain. The massif is a smaller structural unit of the crust than a tectonic plate, and is considered the fourth-largest driving force in geomorphology. The word is taken from French (in which the word also means "massive"), where it is used to refer a large mountain mass or compact group of connected mountains forming an independent portion of a range. One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France. The Face on Mars is an example of an extraterrestrial massif. Massifs may also form underwater, as with the Atlanti ...

Embayment
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129. Bays were sig ...

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...
