The District is moderately populated and situated in the central part of the Chhattisgarh State covers an area of 2854.81sq km. It falls in Survey of India Degree Sheet Nos. 64F and 64G bounded by latitude 21°22' to 22°03' N and longitude 81°07' to 81°55 E. It is surrounded by Durg districts in the south, Rajnandgaon&Kabirdham District in the west, Mungeli districts in the north and Baloda-bazar & Raipur district in the East. Bemetara is the district headquarters and is well connected by road and railway. National Highway No. 12A and connects Bemetara with Kabirdham. Bemetara is also connected by road with Raipur, Baloda-Bazar, Kabirdham and Durg with the other important towns in the district. Acording to NotificationofEnvironment, Forest and Climate Change Ministry,Goverment of India dated15 January 2016, as prescribed in Para 7(iii) and Annexure (x).District Survey Report has been prepared. District Survey report will be prepared in every district for Sand mining or River bed mining and other small minerals mining. The main purpose of preparation of district survey report is to identify the land increase or depositional areas and its infrastructure, Structure and installation distance from where the mining is prohibited and recalculation of annual replenishment and time required for replenishment after mining. 5 This District Survey report contains mainly Geology Mineral wealth details of rivers, Details of Lease and Mining activity in the District along with Sand mining and revenue of minerals. This report also contains details of Forest, Rivers, Soil, Agriculture, Road, Transportation climate etc. The district survey report will be based for evaluation of the application for project and environment clearance of mining activity in the district. 6 2.

Cement Grade Limestone/Dolomite occur in thewhole district. Total 4 Quarry Leases are given in the district for limestone. Total 34 Quarry Leases are given in the district for soil for making bricks in kiln at different villages Out of 31 newelydeclated minor minerals, lease for 1 have been granted for limestone and 27 for dolomite. 33 Ret Ghatfor sand mining on the bank of Shivnath, Kharun and Tandula rivers have been leased out at different villages for sand mining. 2 Mining Leases for runner mounding sand have also been granted at Amti and Thanaud and Karhidihvillage. Approximately 430.26033 lakh Rupees royalty is earned all minerals in the district, out of which 9.00 lakh from major and 421.26033 from minor minerals during the year 2015-16. 7 State Government, is carrying on various Infrastructure development projects in all district , like PachriNirman, Dams, Over bridge Anicuton rivers/nala, approach roads etc. , all above civil works require Sand in different site which is in huge quantity in the district. 8 3.

PROCESS OF DEPOSITION OF SEDIMENTS IN THE RIVERS Sendimentation of rivers of District 6- Process of river sedimentation:- What is erosion? Erosion is natural process, wathering, corrosion, or abrasion can reduce a material into smaller particles. Normally, these smaller units are relocated by water, wing, ice, or man. Erosion removes tosoil, organic material, and other valuable resources. What is sedimentation? Once a material is broken free of the larger mass, it can be carried away and deposited elsewhere. This process of depositing eroded material is known as sedimentation. Some indications of sedimentation are sand dunes, mud in the street around drains, and decreased water holding capacity of stream, reservoir, or pond. Why should we be concerned about erosion and sedimentation? Sediment is responsible for more stream and river degardation than any other pollutant. Deposits of sediments in ditches, streams, and rivers reduce their capacity to store water resulting in more frequent and severe flooding and increased property damage. Accumulations of sediment may result in severe damage to storm drain systers. Many millions of dollars are spent each year to dredge our state waterways, to remove sediments from storm drain systerms, reseroirs, and water treatment plants, and to repair flood damage. Sediment in streams and rivers causes the most damage to aduatic life by severely impacting aquatic animal habitats and degrading water quality. Areas needed for 21 reproduction and food sources are destroyed when fine silts cover the sand and gravel streambed. Decreased clarity of the water prevents sunlight from reaching plants resulting in loss of aquatic plant communities. The result is a reduction in the number and variety of fish and other aquatic life. This impact ofter can see for many miles downstream. Process - Rivers have a lot of energy and because they have energy, they do stuff. The obvious things rivers do with their energy is flow but, besides this, they also transport load, erode load and erode the channel through which they flow. Erosion Erosion is the breaking down of material by an agent. In the case of a river, the agent is water. The water can erode the river’s channel and the river’s load. A river’s load is bits of eroded material, generally rocks, which the river transports until it deposits its load. A river’s channel is eroded late rally and vertically making the channel wider and deeper. The intensity of lateral and vertical erosion is dictated by the stage in the river’s course, discussed in more detail here but essentially, in the upper stage of the river’s course (close to the so urce of the river) there is little horizontal erosion and lots of vertical erosion. In the middle and lower stages vertical erosion is reduced and more horizontal erosion takes place. There are several different ways that a river erodes its bed and banks. The first is hydraulic action, where the force of the water removes rock particles from the bed and banks. This type of erosion is strongest at rapids and waterfalls where the water has a high velocity. The next type of erosion is corrasion. This is where the river’s load acts almost like sandpaper, removing pieces of rock as the load rubs against the bed & banks. This sort of erosion is strongest when the river is transporting large chunks of rock or after heavy rainfall when the river’s flow is 22 turbulent. Corrosion is a special type of erosion that only affects certain types of rocks. Water, being ever so slightly acidic, will react with certain rocks and dissolve them. Corrosion is highly effective if the rock type of the channel is chalk or limestone (an ything containing calcium carbonate) otherwise, it doesn’t have much of an effect. Cavitation is an interesting method of erosion. Air bubbles trapped in the water get compressed into small spaces like cracks in the river’s banks. These bubbles eventually implode creating a small shockwave that weakens the rocks. The shockwaves are very weak but over time the rock will be weakened to the point at which it falls apart. The final type of erosion is attrition. Attrition is a way of eroding the river’s load, no t the bed and banks. Attrition is where pieces of rock in the river’s load knock together, breaking chunks of rock off of one another and gradually rounding and shrinking the load.
