Assessment of Capacity Evaluation and Sedimentation of Totla Doh Reservoir,In Nagpur District By Remote sensing Technique.

Abstract

Water is essential for socioeconomic development and for maintaining healthy economic component of growth, poverty reduction and equality. The livelihood of the poorest sector with higher rates of urbanization, increasing demand for drinking water will put stronger by 2030. The next 25 years are challenging to create hydropower stations, the higher food production at lower rate of water consumption, development of Industrial and Agriculture sector and the economical waste water treatments. Water Resources Management aims at optimizing the available natural water flows and competing needs. Adding uncertainty, climate change will increase the complexity of managing water resources. The mounting challenges due to demand and supply of water, It becomes essential to utilize available storage in minimize rate. It is well established fact that reservoirs constructed on rivers are subjected to sedimentation. A reservoir sedimentation is a natural phenomena. All the reservoirs are bound to suffer a loss in their storage potential because of silt load, over a period of time. To evaluate the performance of every Major and Medium dams ,the accurate sedimentation analysis is essential in every 5-10 years of span. At present the most reliable method of assessment of sedimentation is Remote Sensing Technique. Maharashtra Engineering Research Institute, (MERI) Nashik, has conducted capacity assessment survey of several major and medium dams in Vidarbha Region by Satellite Remote Sensing (SRS) Technique. This Paper deals with the case study of Totla Doh dam for capacity evaluation and sedimentation.This also suggests necessity for planning the water use more effectively.
