Al-arbaâ Valley
Al-arbaâ Valley is a watercourse originating from the Khachna Mountains and flowing through the regions of Ouled Aissa and Sidi Daoud. It empties into the Mediterranean Sea to the east of Djinet, passing through Boumerdès Province. Description Al-arbaâ Valley is one of the main waterways in the eastern drainage basin of Djinet and the western area of Sidi Daoud in Boumerdès Province. This hydro-graphic basin covers an area of approximately 35 square kilometers within the "Al-Droa'a Mountains" of the Khachna range. The tributaries feeding this river descend from an altitude of 550 meters within the municipalities of Ouled Aissa and Sidi Daoud, continuing their flow through the municipality of Djinet until reaching the Mediterranean Sea. Its mouth lies on the border between Sidi Daoud and Djinet. This watercourse benefits from numerous mountain springs, in addition to rainfall and melting snow, which collectively gather its water. It plays a vital role in Boumerdès Prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pollution
Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants Human impact on the environment, have a human source, such as manufacturing, Extractivism, extractive industries, poor waste management, transportation or Agricultural pollution, agriculture. Pollution is often classed as point source pollution, point source (coming from a highly concentrated specific site, such as a factory, Environmental effects of mining, mine, construction site), or nonpoint source pollution (coming from a widespread distributed sources, such as microplastics or agricultural runoff).

Tourism In Algeria
Tourism is travel for pleasure, and the Commerce, commercial activity of providing and supporting such travel. World Tourism Organization, UN Tourism defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be Domestic tourism, domestic (within the traveller's own country) or International tourism, international. International tourism has both incoming and outgoing implications on a country's balance of payments. Between the second half of 2008 and the end of 2009, tourism numbers declined due to a severe Economy, economic slowdown (see Great Recession) and the outbreak of the 2009 2009 flu pandemic, H1N1 influenza virus. These numbers, however, recovered until the COVID-19 pandemic put an abrupt end to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Beaches
This is a list of beaches of the world, sorted by country. A beach is a landform along the shoreline of an ocean, sea, lake, or river. It usually consists of loose particles, which are often composed of rock, such as sand, gravel, shingle, pebbles, or cobblestones. Beaches typically occur in areas along the coast where wave or current action deposits and reworks sediments. The particles comprising a beach are occasionally biological in origin, such as mollusc shells or coralline algae.

Discharge Regime
Discharge regime, flow regime, or hydrological regime (commonly termed river regime, but that term is also used for other measurements) is the long-term pattern of annual changes to a stream's discharge at a particular point. Hence, it shows how the discharge of a stream at that point is expected to change over the year. It is thus the hydrological equivalent of climate. The main factor affecting the regime is climate, along with relief, bedrock, soil and vegetation, as well as human activity. Like general trends can be grouped together into certain named groups, either by what causes them and the part of the year they happen (most classifications) or by the climate in which they most commonly appear (Beckinsale classification). There are many different classifications; however, most of them are localized to a specific area and cannot be used to classify all the rivers of the world. When interpreting such records of discharge, it is important to factor in the timescale over wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Redbreast Tilapia
The redbreast tilapia (''Coptodon rendalli'') is a species of fish in the family Cichlidae. It is found widely in the southern half of Africa. Its natural habitats are freshwater lakes and freshwater marshes. It is known as the redbreast kurper in South Africa. Distribution The species is found in the drainage basins of the upper Congo River and the Kasai River, in Lake Tanganyika, Lake Malawi, Zambezi River, and the coastal regions of the Zambezi outlet to KwaZulu-Natal, as well as in the Limpopo River, the Okavango River, and the Cunene River. They have been established as edible fish in several countries. Description ''C. rendalli'' grows to a maximum length of 45 cm and a maximum weight of 2.5 kg, and possesses a high-backed, sideways oblate body. Its body height is 42.2 to 49.4% of its standard length, and its head length is 31.1% to 37.5% of standard length. The top of its head is convex, or sometimes concave in large specimen due to the continued growth of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Carp
The silver carp or silverfin (''Hypophthalmichthys molitrix'') is a species of freshwater cyprinid fish, a variety of Asian carp native to China and eastern Siberia, from the Amur River drainage in the north to the Xi Jiang River drainage in the south. Although a threatened species in its natural habitat, it has long been cultivated in China as one of the "Four Famous Domestic Fish" (''四大家鱼'') together with bighead carp, black carp and grass carp. By weight, more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other fish species. The species has also been introduced, or spread by connected waterways, to at least 88 countries around the world. The reason for importation was generally for use in aquaculture, but enhancement of wild fisheries and water quality control have also been intended on occasion. In ...

Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. Nelumbo nucifera, lotus). Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems. Mariculture, commonly known as marine farming, is aquaculture in seawater habitats and lagoons, as opposed to freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain Fish as food, fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environme ...

Rain
Rain is a form of precipitation where water drop (liquid), droplets that have condensation, condensed from Water vapor#In Earth's atmosphere, atmospheric water vapor fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectricity, hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convection, convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and ...
