- 6. Idle location forits implementation • a narrow part of a deep river valley • Less earthquake-prone zones • Areas having less frequent landslides • Areas which have slope-stability
- 7. Objectives • Power generation •Water supply • Stabilization of water flow • Irrigation • Flood prevention • Land reclamation • Water diversion • Navigation
- 9. Hydro power • Oneof the main objects of a multi purpose project is to generate energy. • Hydroelectric power is a major source of electricity in the world. • Many countries that have rivers with adequate water flow, that can be dammed for power generation purposes.

- 12. Apart from thesefactors, these multi-purpose projects due to their important aims often leads to: 1. Water Disputes 2. Downstream erosion 3. Reservoir Sedimentation
- 13. Why opposed byenvironmentalist? • Fragmentation of river ecosystems and has Impacts on biodiversity • Barrier for movement of migratory fish like the salmon, thereby affecting its population . • Reduction in natural biodiversity along riverbanks due to reduced natural flooding. • Alters water temperature downstream, affecting plant and animal life in the reservoir and the river. • Cropping patterns changed to more water intensive crops thus it affects soil quality

- 16. Achieving the goals •flood Control • promotion & operation of schemes for irrigation • water supply for domestic & industrial use • navigation & drainage • Generation, transmission & distribution of electrical energy • Maithon Dam is one of the most popular dams in Jharkhand and one of the most successful multipurpose projects in India.
- 17. HYDRO ELECTRICITY • Thereis an underground power station, the first of its kind in the whole of South East Asia. • The power station has a total generating capacity of 60 MW with 3 units of 20 MW each. MHPS is located at almost 1000 feet below the water level. • Installed capacity: 60 MW
- 18. Limitations due toenvironment • The rain water takes a lot of soil with it and the same settles down in the reservoir causing decrease in the depth. • There is also a pollution threat to the town as many industries are being set up in the locality. • The underground water level has already decreased over the years which further strains the water resources.
- 19. A story ofsuccess
- 20. • In India,most of the multi –purpose projects have served their goals with time showing a great deal of significant growth in these sectors. • It has resulted not only in better irrigation situation but also helped in generating hydro power. • Frequent checks and keen monitoring will help in continuing the services and benefits such a project provides.
- 21. This assignment helpedin two very specific ways: • It gave me an insight of the working of a a hydraulic project. • It also helped me in understanding the social impact of any big scheme or program taken up by the govt.
