Nahal Barak
Nahal Barak ( he, נחל ברק), also known as Barak gorge or Barak river, is an intermittent stream and canyon in the Arava desert in Israel's South District. When it is flooded, Nahal Barak forms part of the network of streams that drain the Negev desert. The stream itself is 18 km long and flows in a general easterly direction into the Nahal HaArava, which in turn flows northward into the southernmost end of the Dead Sea. The stream cuts through limestone Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime.

Intermittent Stream
Intermittent, temporary or seasonal rivers or streams cease to flow every year or at least twice every five years.(Tzoraki et al., 2007) Such rivers drain large arid and semi-arid areas, covering approximately a third of the earth's surface. The extent of temporary rivers is increasing, as many formerly perennial rivers are becoming temporary because of increasing water demand, particularly for irrigation. Despite inconsistent water flow, intermittent rivers are considered land-forming agents in arid regions, as they are agents of significant deposition and erosion during flood events. The combination of dry crusted soils and the highly erosive energy of the rain cause sediment resuspension and transport to the coastal areas.(Tzoraki et al., 2009) They are among the aquatic habitats most altered by human activities. During the summer even under no flow conditions the point sources are still active such as the wastewater effluents, resulting in nutrients and organic pollutants ...

Arabah
The Arabah, Araba or Aravah ( he, הָעֲרָבָה, ''hāʿĂrāḇā''; ar, وادي عربة, ''Wādī ʿAraba''; lit. "desolate and dry area") is a loosely defined geographic area south of the Dead Sea basin, which forms part of the border between Israel to the west and Jordan to the east. The old meaning, which was in use up to the early 20th century, covered almost the entire length of what today is called the Jordan Rift Valley, running in a north–south orientation between the southern end of the Sea of Galilee and the northern tip of the Gulf of Aqaba of the Red Sea at Aqaba– Eilat. This included the Jordan River Valley between the Sea of Galilee and the Dead Sea, the Dead Sea itself, and what today is commonly called the Arava Valley. The contemporary use of the term is restricted to this southern section alone. Geography The Arabah is in length, from the Gulf of Aqaba to the southern shore of the Dead Sea. Topographically, the region is divided into three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Israel
Israel (; he, יִשְׂרָאֵל, ; ar, إِسْرَائِيل, ), officially the State of Israel ( he, מְדִינַת יִשְׂרָאֵל, label=none, translit=Medīnat Yīsrāʾēl; ), is a country in Western Asia. It is situated on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea, and shares borders with Lebanon to the north, Syria to the northeast, Jordan to the east, and Egypt to the southwest. Israel also is bordered by the Palestinian territories of the West Bank and the Gaza Strip to the east and west, respectively. Tel Aviv is the economic and technological center of the country, while its seat of government is in its proclaimed capital of Jerusalem, although Israeli sovereignty over East Jerusalem is unrecognized internationally. The land held by present-day Israel witnessed some of the earliest human occupations outside Africa and was among the earliest known sites of agriculture. It was inhabited by the Canaanites ...

Southern District (Israel)
The Southern District ( he, מחוז הדרום, ''Meḥoz HaDarom''; ar, لواء الجنوب) is one of Israel's six administrative districts, the largest in terms of land area but the most sparsely populated. It covers most of the Negev desert, as well as the Arava valley. The population of the Southern District is 1,086,240 and its area is 14,185 km2. Its population is 79.66% Jewish and 12.72% Arab (mostly Muslim), with 7.62% of other origins. The district capital is Beersheba, while the largest city is Ashdod. Beersheba's dormitory towns of Omer, Meitar, and Lehavim are affluent on an Israel scale, while the development towns of Dimona, Sderot, Netivot, Ofakim, and Yeruham and the seven Bedouin cities are lower on the socio-economic scale.

Negev Desert
The Negev or Negeb (; he, הַנֶּגֶב, hanNegév; ar, ٱلنَّقَب, an-Naqab) is a desert and semidesert region of southern Israel. The region's largest city and administrative capital is Beersheba (pop. ), in the north. At its southern end is the Gulf of Aqaba and the resort city and port of Eilat. It contains several development towns, including Dimona, Arad and Mitzpe Ramon, as well as a number of small Bedouin towns, including Rahat and Tel Sheva and Lakiya. There are also several kibbutzim, including Revivim and Sde Boker; the latter became the home of Israel's first Prime Minister, David Ben-Gurion, after his retirement from politics. Although historically part of a separate region (known during the Roman period as Arabia Petraea), the Negev was added to the proposed area of Mandatory Palestine, of which large parts later became Israel, on 10 July 1922, having been conceded by British representative St John Philby "in Trans-Jordan's name". Despite this, the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nahal HaArava
The Arava Stream ( he, נחל הערבה, Nahal HaArava) is an intermittent stream (occasionally flowing in the rainy, winter season) that flows from the approximate mid-point of the Arava desert in Israel's Southern District northward. It is 89 km long, and in many parts, serves as the actual border between Israel and Jordan. The stream originates on the crest of the Notza Ridge, which forms the watershed divide between the Dead Sea and the Red Sea, and from which all streams in the Arava desert flow either north to the Dead Sea or south to the Red Sea. The stream's prominent tributaries include: Nahal Paran, Nahal Barak, Nahal Tzin, Nahal Tzafit, and Nahal Nekorot. In addition to Israel and Jordan, parts of its drainage basin are in the Sinai Peninsula, Egypt. Northern flow The stream flows into the area of evaporation ponds in what used to be the southernmost end of the Dead Sea and divides these ponds into the Israel area (managed by the Dead Sea Works) and the Jordan ...

Dead Sea
The Dead Sea ( he, יַם הַמֶּלַח, ''Yam hamMelaḥ''; ar, اَلْبَحْرُ الْمَيْتُ, ''Āl-Baḥrū l-Maytū''), also known by other names, is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River. As of 2019, the lake's surface is below sea level, making its shores the lowest land-based elevation on Earth. It is deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2% (in 2011), it is one of the world's saltiest bodies of water – 9.6 times as salty as the ocean – and has a density of 1.24 kg/litre, which makes swimming similar to floating. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea's main, northern basin is long and wide at its widest point. The Dead Sea has attracted visitors from around the Mediterranean Basin for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals 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, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
