Noyyal River
The Noyyal River is a small river in Western Tamil Nadu, and a tributary of Kaveri River. It rises from the Vellingiri hills in the Western Ghats in Tamil Nadu, very close to Kerala border, and flows through many villages and the cities of Coimbatore, and Tirupur finally draining into the Kaveri River at Noyyal, a village in Karur district named after the river itself. The river's basin is long and wide and covers a total area of . Cultivated land in the basin amounts to while the population density is 120 people per km² (311/mi²) in the countryside, and 1000 people per km² (2590/mi²) in the cities. The area is known for its scanty rainfall and the development of the Noyyal River Tanks System to hold any overflow from the rains plus the water of the Northeast and Southwest monsoon season was ecologically important. Kausika river in the northern side of Coimbatore district along with its lake and pond systems is an important tributory. The long tributary of the Kaver ...

Percolation
Percolation (from Latin ''percolare'', "to filter" or "trickle through"), in physics, chemistry and materials science, refers to the movement and filtering of fluids through porous materials. It is described by Darcy's law. Broader applications have since been developed that cover connectivity of many systems modeled as lattices or graphs, analogous to connectivity of lattice components in the filtration problem that modulates capacity for percolation. Background During the last decades, percolation theory, the mathematical study of percolation, has brought new understanding and techniques to a broad range of topics in physics, materials science, complex networks, epidemiology, and other fields. For example, in geology, percolation refers to filtration of water through soil and permeable rocks. The water flows to recharge the groundwater in the water table and aquifers. In places where infiltration basins or septic drain fields are planned to dispose of substantial amounts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheyyar River
Cheyyaru River is an important seasonal river that runs through the Tiruvannamalai District of the state of Tamil Nadu in South India.

Water
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vap ...

Orathuppalayam Dam
The Noyyal Orathuppalayam Dam and Reservoir, also called Orathuppalayam Dam, is located on the Noyyal River between Chennimalai and Kangayam in Tirupur District, Tamil Nadu, South India. The dam is situated north of Kangayam and east of Tirupur. The dam was built in 1992. It has an ayacut of over 10,000 acres in Tirupur and Karur Districts. It was used by the farmers only for five years as it became a storage tank for textile effluents after that. The farmers, who depended on the dam and river for irrigation, stopped the farm activity in their land. Due to the sad conversion of Irrigation dam to Effluent tank, the people living down river in the Tirupur, Karur District are negatively affected. From 1992 the deterioration has started and caused migration. Ungampalayam in the K.Paramathi block, Karur district is one such example. Even the villages near the dam in Chennimalai, Uttukuli area are affected. Kodumanal, famous archaeological site containing Roman coins, potteries a ...

Kongu Nadu
Kongu Nadu, also known by various names as Kongu Mandalam and Kongu belt, is a geographical region comprising present day parts of western Tamil Nadu, southeastern Karnataka and eastern Kerala. In the ancient Tamilakam, it was the seat of the Chera kings, bounded on the east by Tondai Nadu, on the south-east by Chola Nadu and on the south by Pandya Nadu regions. The region was ruled by the Cheras during Sangam period between c.1st and the 4th centuries CE and it served as the eastern entrance to the Palakkad Gap, the principal trade route between the west coast and Tamil Nadu.

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. 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 have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, ...

History
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of th ...
