The document discusses sources and utilization of water resources in India. It outlines four main sources of water: atmospheric, surface, ground, and ocean water. It then describes various surface water bodies like rivers and lakes. It also explains that groundwater in some areas is replenished by rivers while some peninsular areas have low water tables. Lastly, it lists several multi-purpose river projects across India that were constructed for irrigation and hydroelectric power generation purposes.

1. WATER
RESOURCES

2. Sources of
water
• Atmospheric water
• Surface water
• Ground water
• Ocean water

5. Reach earth tthrough
1. Rain
2. Snow
3.Dew negligible
very seasonal
117cm average
less rainfall in desert

8. Surface water
• River, lake, pond, tank
• 10,360 rivers include Ganga, kaveri, brahmaputra, mahanadi
• Lake like Wular, Loktak are confined only in particular area

13. Ground water
• Ganga and Brahmaputra replenish ground water about 46 percent
• Penisular area are deprive of ground water due to impervious rock
and water table is very low
• Tamil Nadu and M. P has high potential
• Low water table is due to overdrawing of water, deforestation and
runaway waters from river and rain due to various reason

16. Ocean water
• Due to peninsula projection large part of India has free access to sea
and ocean
• Numerous Lagoons and backwater gives another advantage in some
coastline areas
• But due to its salinity it has limited ues

20. Utilisation
• Canal
• Well and tube well
• Tank

24. Multi-purpose river projects
• Bhakra Nangal Project
• Damodar valley Project
• Hirakud Project
• Beas
• Rajasthan Canal
• Kosi
• Nagarjuna Sagar
• Tungabadra
• Chambal
• Sardar Sarovar

26. Bhakra Nangal
Project
• Sutlej river
• Joint venture of Punjab, haryana, Rajasthan and delhi
• Highest in the world
• Irrigated 1.5million hectares
• Produce 1204MW

28. Damodar Valley Project
• 4dams built on Damodar river
• 5.5lakhs hectares
• 118MW
• CONTROL FLOODS

30. Hirakud Project
• Mahanadi river Orissa
• Longest in world
• 350 MW
• 1M hectares

32. Chambal Project
• M.P and Rajasthan
• 5.6lakh hectares
• 386MW

34. Tungabhadra
Project
• A. P and Karnataka
• 3.9lakh hectares
• Tungabhadra is a Krishna river tributeries
• Dam built at mallapuram

36. Beas
Project
