As a seasonal river it carries the collected water after the rains in the catchment area.S Nazneen and F Begum (1988) Hydrological studies of Lyari River. Pakistan Journal of Scientific and Industrial Research. Vol. 31, No. 1, pp. 26-29. History Until the 1970s, the river held clean water and fish, with farming activities on its banks. However, after the independence of Pakistan from British colonialism in 1947, when Karachi was announced as the capital city of the new country, a large influx of refugees from various Indian states as well as from other provinces of Pakistan came to live in the city. With rapid growth of the city's economy, industry, and population, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lyari
Lyari (Urdu: ; sd, لیاري) is a historic locality in Karachi, Pakistan. It is the most densely-populated part of Karachi, and is one of its earliest settled areas.Sarwat Viqar (2014) Constructing Lyari: place, governance and identity in a Karachi neighbourhood, South Asian History and Culture, 5:3, 365-383, DOI:10.1080/19472498.2014.905335 http://dx.doi.org/10.1080/19472498.2014.905335 History Lyari is said to be one of the oldest inhabited parts of Karachi, and is referred to by its residents as the "Mother of Karachi." Its name is said to be derived from a ''Lyar'' - a tree which grows in a graveyard.

Controlled-access Highway
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include ''throughway'' and '' parkway''. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following the Vienna convention, the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals, intersections or property access. They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to the highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials ...

Flood Barrier
A flood barrier, surge barrier or storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls, levees (also known as dikes), and other constructions and natural geographical features. Flood barrier may also refer to barriers placed around or at individual buildings to keep floodwaters from entering the buildings. Examples Delta Works The Delta Works in the Netherlands is the largest flood protection project in the world. This project consists of a number of surge barriers, the Oosterscheldekering being the largest surge barrier in the world, long. Other examples include the Maeslantkering, Haringvlietdam and the Hartelkering. Thames Barrier The Thames Barrier is the world's second largest movable flood barrier (after the Oosterscheldekering and the Haringvlietdam) and is locate ...

Squatter
Squatting is the action of occupying an abandoned or unoccupied area of land or a building, usually residential, that the squatter does not own, rent or otherwise have lawful permission to use. The United Nations estimated in 2003 that there were one billion slum residents and squatters globally. Squatting occurs worldwide and tends to occur when people who are poor and homeless find empty buildings or land to occupy for housing. It has a long history, broken down by country below. In developing countries and least developed countries, shanty towns often begin as squatted settlements. In African cities such as Lagos much of the population lives in slums. There are pavement dwellers in India and in Hong Kong as well as rooftop slums. Informal settlements in Latin America are known by names such as villa miseria (Argentina), pueblos jóvenes (Peru) and asentamientos irregulares (Guatemala, Uruguay). In Brazil, there are favelas in the major cities and land-based movements. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effluent
Effluent is wastewater from sewers or industrial outfalls that flows directly into surface waters either untreated or after being treated at a facility. The term has slightly different meanings in certain contexts, and may contain various pollutants depending on the source. Treating wastewater efficiently is challenging, but improved technology allows for enhanced removal of specific materials, increased re-use of water, and energy production from waste. Definition Effluent is defined by the United States Environmental Protection Agency (EPA) as "wastewater–treated or untreated–that flows out of a treatment plant, sewer, or industrial outfall. Generally refers to wastes discharged into surface waters". The ''Compact Oxford English Dictionary'' defines effluent as "liquid waste or sewage discharged into a river or the sea". Wastewater is not usually described as effluent while being recycled, re-used, or treated until it is released to surface water. Wastewater percolate ...

Sewage
Sewage (or domestic sewage, domestic wastewater, municipal wastewater) is a type of wastewater that is produced by a community of people. It is typically transported through a sewer system. Sewage consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality. Sub-types of sewage are greywater (from sinks, bathtubs, showers, dishwashers, and clothes washers) and blackwater (the water used to flush toilets, combined with the human waste that it flushes away). Sewage also contains soaps and detergents. Food waste may be present from dishwashing, and food quantities may be increased where garbage disposal units are used. In regions where toilet paper is used rather than bidets, that paper is also added to the sewage. Sewage contains macro-pollutants and micro-pollutants, and may also incorporate some municipal solid waste and pollutants from industrial wastewater. Sewage usually travels from a building's plum ...

Waste Water
Wastewater is water generated after the use of freshwater, raw water, drinking water or saline water in a variety of deliberate applications or processes. Another definition of wastewater is "Used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff / storm water, and any sewer inflow or sewer infiltration". In everyday usage, wastewater is commonly a synonym for sewage (also called sewerage, domestic wastewater, or municipal wastewater), which is wastewater that is produced by a community of people. As a generic term wastewater may also be used to describe water containing contaminants accumulated in other settings, such as: * Industrial wastewater: waterborne waste generated from a variety of industrial processes, such as manufacturing operations, mineral extraction, power generation, or water and wastewater treatment. ** Cooling water, released with potential thermal pollution after use to condense steam or reduce machinery ...

Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...
