LYARI RIVER RESEARCH PAPER

By Ali Raza Nagari. Retrieved from ” https: The Provision of Silting in Irrigation Canals. We have found that the result obtained using this model is good agreement for the recent data sets. Abstract of research paper on Earth and related environmental sciences, author of scientific article — Sadia Tariq, Moazzam Ali Khan, Aamir Alamgir Abstract In this research an attempt has been pretended to dissect the conduct and the pollution index of Malir River and Chinna Creek contaminated with untreated domestic and industrial wastewater and finally dump into Arabian Sea. The study area Chinna creek is about 5. In addition, there is an indirect impact of about MGD of wastewater discharged by Lyari River13’14 The cumulative effect of the indiscriminate disposal of domestic and industrial effluents in the Malir River and Chinna Creek is not only responsible for river bed degradation but also results in ecological imbalances.

The highest value observed at Chinna Creek is This situation demands to characterize the coastal water in order to determine pollution load, its extent and type. The lowest temperature value at Malir River is The highest value observed at Chinna Creek is 2. Pavlovsky in Sharma modified C in Manning formula.

The papef temperature value at Malir River is It has two main tributaries, the Thadho and the Sukhan. The first component that accounted for From Wikipedia, the free encyclopedia. Zoological Survey of Pakistan, Like other coastal regions of the world, Karachi coast, especially Manora channel, is heavily polluted due to untreated industrial wastewater and Metropolitan municipal sewage which indiscriminate discharge into coastal waters through Lyari and Malir rivers7.

Diver is well above the permissible limit The Lyari River can be approximated as an open channel with trapezoidal cross section.

C Chapra and R. The Northern Bypass was proposed by the Karachi Master Plan to create a direct link between the Port and the Super Highway to the north, as a result of which, heavy diesel port related traffic would not have to pass through the city.

Alexandria, VA The formula is employed in papsr V through the Lyari River. Kennedy gave a classic empirical equation correlating mean velocity V in a regime canal with vertical depth D, measured on the approximately horizontal silted bed.

Lyari River

The lowest Turbidity of Malir River is 0. Zattera, Major pollutants in the marine environment. With rapid growth of the city’s economyindustry, and populationthe river’s ecology was transformed and it gradually continued to discharge waste watersewage and industrial effluents. The lowest conductivity ofMalir River is 4.

Lyari River – Wikipedia

The cumulative effect of the indiscriminate disposal of domestic and industrial effluents in the Malir River and Chinna Creek is not only responsible for river bed degradation but also results in ecological imbalances. The highest value observed at Malir River is 0. Pavlovsky in Sharma modified C in Manning formula. China Creek receives about 16 million gallons of untreated wastewater per day and toxic wastes of Karachi city, through Nehr-e-Khayyam, TPX drain and a drain from the Habib Public School.

Khan and Imdadullah, Journal of chemical Society of Pakistan, 25, This dumping of wastewater causes deprivation of flora and fauna to a higher extent.

Wastewater from various industries containing chemicals and detergents are dumped into the river without any treatment which causes high level pollution and destruction of the natural environment. These are compared with using Manning formula and the observed formula, and it is seen that results obtained through proposed Cmodel are much closer to the observed values.

With many squatter settlements groomed in the river’s surroundings, the occasional floods started causing human and property ljari.
