Introduction In pursuance to the Gazette Notification, Ministry of Environment, Forest and Climate Change (MoEF & CC), the Government of India Notification No. S.O.3611 (E) dated 25.07.2018 laid procedure for preparation of District Survey Report for sand mining or river bed mining. The main purpose of preparation of District Survey Report is to identify the mineral resources and developing the mining activities along with other relevant data of the District. All rivers in Tiruppur District are ephemeral (only seasonal) in nature and carry only floodwater during monsoon period and none of them are perennial. These rivers cannot be used for irrigation purpose to the expected level because of low precipitation. The monsoon rainfall is erratic and only during stormy days precipitation occurs. The drainage pattern is mostly parallel to sub parallel and drainage density is very low. This District Survey report guide systematicand scientific utilization of natural resources, so thatpresent and futuregeneration may be benefitted at large. The purpose of District SurveyReport (DSR) is “Identification of areas of aggradations or depositionwhere mining can be allowed; and identification of areas of erosion andproximity to infrastructural structuresand installations where miningshould be prohibited”. The District Survey report (DSR) contain mainly datapublished and endorsed by various Departments and websites aboutGeology of the area, Mineral Wealth details, Details of Lease and Miningactivity in the District along with Revenue of Minerals. This report alsocontains details of Forest, Rivers, Soil, Agriculture, Road, Transportationand Climate etc., 4 | P a g e 2. Overview of Mining Activity in the District Mining activities carried out in the District is Opencast Semi Mechanized/ Mechanized and Manual method. The Economic important mineral found in Tiruppur District are mainly Gypsum, Kankar, Magnesite, Dunite, Quartz, Feldspar, varieties of colour Granites (Dimensional stones), Rough stone (Aggregates) and Gravel/Earth. Mining activities based on these minerals are very less. However, numerous Rough Stone quarries are under operation for production of construction materials and earth fill (gravel) in Kodangipalayam, Morattupalayam, Madathukulam, Kiranur, Moolanur areas in the district. In addition to above, ‘Dimensional Stones’ (Granite) is also available in Avinashi, and Kangeyam Taluks. The office of the Assistant Director, Department of Geology and Mining is functioning under the control of District Collector, Tiruppur.

Processes of Deposition of Sediments in the Rivers of the District River sediment refers to the mixture of mineral matters which are derived from the weathering and erosion of rocks present in the river bed. Breaking down of rocks by a geological agent, here it is a river (flow of water), is called erosion. The erosion of rocks occurs in many ways. Weathering is described as disintegration and decomposition of rocks due to change in physical and chemical conditions of the rock. Sediments are derived by these natural processes. Sediments are subsequently transported by water and/or by the force of gravity acting on the sediments. Sediments become the river’s load and the river transport this loads through its course. Transportation of the sediments depends on the energy of the river. Boulders are transported by traction and are rolled along the bed of the river. Slightly smaller particles, such as pebbles and gravel, are transported by saltation. This is where the load bounces along the bed of the river because the river has enough energy to lift the particles off the bed but the particles are too heavy to travel by suspension. Fine particles like clay and silt are transported in suspension; they are suspended in the water. Most of a river’s load is transported by suspension. Solution is a special method of transportation. This is where particles are dissolved into the water so only rocks that are soluble, such as limestone or chalk, can be transported in solution. Deposition occurs when forces responsible for sediment transportation are no longer sufficient to overcome the forces of gravity and friction which are creating a resistance to motion. To transport load, a river needs to have energy at the same time when a river loses energy, it is forced to deposit its load. One of the following ways, a river could lose its energy: 1. Reduction in the discharge: Reduction in discharge may be due to lack of precipitation and evaporation and abstraction by human activity. 2. Change in the river gradient: If the gradient of the river’s course flattens out, the river will deposit its load because it will be travelling a lot slower. When a river meets the sea a river will deposit its load because the gradient is generally reduced at sea level and the sea will absorb a lot of energy. 8 | P a g e Plate1. A. Schematic diagram of process on meander bend. Plate1. B. Meandering of Amaravathi River, Near Veerachimangalam, Tiruppur district. Much of the material will be carried in suspension and loads in suspension erode the river banks by abrasion. When rivers flow over flatter land, they form large bends called 9 | P a g e meanders. As a river goes around a bend, most of the water is pushed towards the outside causing increased erosion. The river is now eroding sideways into its banks rather than downwards into its bed, a process called lateral erosion (Plate 1. A & B). On the inside of the bend, in contrast, there is much less water. The river will therefore be shallow and slow flowing. It cannot carry as much material and so sand and gravels will be deposited.

Chennai: Department of Geography, University of Madras and Faculty of Environmental Studies, York University. Pages 150 – 157. INDUSTRIAL EFFLUENT AND HEALTH STATUS- A CASE STUDY OF NOYYAL RIVER BASIN Dr. K. Govindarajalu * C.B.M. College, Kovaipudur, Coimbatore, India. Abstract Industrial pollution has been and continues to be, a major factor causing the degradation of the environment around us, affecting the water we use, the air we breathe and the soil we live on. But of these, pollution of water is arguably the most serious threat to current human welfare. Environmental pollution is an ‘externality’ in welfare economics. An externality is present whenever individual A’s utility and production relationships include real (i.e. non-monetary) variables, whose values are chosen by others (persons, corporations, governments) without particular attention to the effects on A’s welfare (Baumol and Oates, 1988). An externality can be either beneficial (positive) or harmful (negative). Negative externalities include noise pollution by aircrafts using an airport, which enters as a real variable in the utility functions of persons living in the neighbourhood, and the pollution of a river, which enters as a real variable in the production function of water-supply undertakings drawing from the river or agriculture. The present study is mainly aimed at studying the nature and impact of water pollution in the Noyyal river basin in Coimbatore, Erode and Karur districts.

  • Shankar Ias Academy Test 18 - Geography - Full Test - Answer Key
    SHANKAR IAS ACADEMY TEST 18 - GEOGRAPHY - FULL TEST - ANSWER KEY 1. Ans (a) Explanation: Soil found in Tropical deciduous forest rich in nutrients. 2. Ans (b) Explanation: Sea breeze is caused due to the heating of land and it occurs in the day time 3. Ans (c) Explanation: • Days are hot, and during the hot season, noon temperatures of over 100°F. are quite frequent. When night falls the clear sky which promotes intense heating during the day also causes rapid radiation in the night. Temperatures drop to well below 50°F. and night frosts are not uncommon at this time of the year. This extreme diurnal range of temperature is another characteristic feature of the Sudan type of climate. • The savanna, particularly in Africa, is the home of wild animals. It is known as the ‘big game country. • The leaf and grass-eating animals include the zebra, antelope, giraffe, deer, gazelle, elephant and okapi. • Many are well camouflaged species and their presence amongst the tall greenish-brown grass cannot be easily detected. The giraffe with such a long neck can locate its enemies a great distance away, while the elephant is so huge and strong that few animals will venture to come near it. It is well equipped will tusks and trunk for defence. • The carnivorous animals like the lion, tiger, leopard, hyaena, panther, jaguar, jackal, lynx and puma have powerful jaws and teeth for attacking other animals. 4. Ans (b) Explanation: Rivers of Tamilnadu • The Thamirabarani River (Porunai) is a perennial river that originates from the famous Agastyarkoodam peak of Pothigai hills of the Western Ghats, above Papanasam in the Ambasamudram taluk.

Accepted 23 October, 2012 Assessment of water quality in Noyyal River from 20/12/2010 to 27/12/2011 was carried out in this study. Water samples were collected from the Noyyal River at a stretch of 3800 m. The sampling locations have been fixed at every 50 m. The parameters were estimated such as dissolved oxygen (DO), pH, Temperature, chemical oxygen demand (COD), total dissolved solids (TDS), Sulphate, Chloride, total hardness etc. This study had two phases. In the first phase, the estimation of water quality parameters was carried out and in the second phase water quality index have been determined based on the existing standards. The effects of municipal sewage on river water quality have also been investigated. The depletion of DO concentration due to the simultaneous effect of water pollution, thus leads to more uncertainty about the survival of DO dependent aquatic species. From the study, it revealed that TDS, sulphate, chloride, and hardness were estimated to be high concentration at sampling location 10 (S 10 ). Among the sample locations, in most of the places, high concentration of TDS, Hardness, sulphate and chloride and low level of DO were observed.

  • Augmentation of Groundwater Resources in the Hard Rock Region of Noyyal River Basin, Tamil Nadu, India
    Augmentation of Groundwater Resources in the Hard Rock Region of Noyyal River Basin, Tamil Nadu, India C. Mayilswami Professor (SWCE), Department of Agriculture Karunya Institute of Technology and Sciences, (Deemed to-be University) Karunyanagar, Coimbatore, Tamil Nadu, India [email protected] Abstract Worldwide rapid growth of population, industries and agricultural activities has brought about a steep increase in water demands which have to be met from available surface and groundwater resources. Many parts of the world have diverse hydro-geological and hydro-meteorological conditions and so is the diversification in its hydrological problems which are mostly governed by the regional conditions. Vagaries of monsoon and withdrawal of groundwater in excess to replenishment of aquifer system in many parts of India and elsewhere results into continuous declining of water table causing economic problems and deterioration of water quality. In case of Tamil Nadu, the problem is manifold in hard rock regions where the water table has gone below the weathered zone and it could be extracted only from deeper fractured zones. The aquifer systems in many hard rock areas have been over exploited. At many places many farmers have drilled borewell without knowing the potential of aquifer system and thereby end up with debt trap due to failure of the borewells. Groundwater is a renewable resource and its spatio-temporal availability on annual basis is almost fixed. Groundwater recharge and its conservation through judicious use can increase its availability to some extent. Hence, management of groundwater resources in a planned manner along with surface water resources is necessary for its sustainability.

    Competing Demand for Water in Tamil Nadu: Urbanisation, Industrialisation and Environmental Damages in the Bhavani and Noyyal Basins (1880s-2000s) Velayutham Saravanan* Abstract This article attempts to analyse, in a historical perspective (1881-2002), the emergence of competing demand for water caused by the diversion of river basin water to meet the demand of the urban domestic use and industrial needs and its consequential damage to the ecology and environment, which further aggravated the problem, in the Bhavani and Noyyal river basins of Tamil Nadu. It examines the diversion of water for the domestic and industrial sectors that caused a great threat to the ecology, environment and health of the people and to the flora and fauna of these regions, which further aggravated the competing demand situation leading to 'water market' in the basin areas. Further, it also analyses the role of the state, how it further motivated the competing demand for water, thereby neglecting the ecology and environment of these river basins. On the one hand, it provides water to the pollution- causing industries by diverting water from the river basins, where there is already an acute scarcity of water. On the other hand, the diverted water is getting polluted due to the ineffective pollution control measures of the state, further aggravating the situation for competing demand for water and worsening the environmental conditions in the river basins. In short, this article examines the proliferation factors for water demand creating competition in the basin areas and the consequence of environmental damages that not only created 'water market' but also posed great threat to the ecology, environment and people in the Bhavani and Noyyal river basins of Tamil Nadu since the late 19th century up till the early years of the 21st century (1881-2002).
