Water Resources Class 10 Notes Inside the Chapter

The chapter opens with the water cycle. Three-fourths of the earth's surface is covered with water, but only a small share is freshwater that we can use. It comes from surface run-off and groundwater, and the hydrological cycle keeps renewing it, so water is a renewable resource. Yet many regions still face water scarcity.

Water scarcity is not always about low rainfall. By 2025, nearly two billion people are predicted to live in absolute water scarcity. It is often caused by over-exploitation, excessive use, and unequal access.

• Main causes: a large and growing population, more demand for food, and over-exploitation of groundwater for irrigation.
• Industry and cities: industries and dense urban colonies pump groundwater and add pressure on fragile water resources.
• Poor quality: water polluted by domestic and industrial waste, pesticides, and fertilisers is unsafe for human use.

Multi-Purpose River Projects and Dams in the Class 10 Geography PDF

Dams were once built only to store river water for irrigation. Today they serve many uses at once, so they are called multi-purpose projects. One dam can give power, water supply, and flood control together.

Jawaharlal Nehru called the dams the "temples of modern India" because they joined farming, industry, and the urban economy. But in recent years, large dams have faced strong opposition for harming rivers and displacing people.

• Bhakra-Nangal project: on the Sutlej-Beas basin, used for both hydel power and irrigation.
• Hirakud project: on the Mahanadi basin, combines water conservation with flood control.
• Sardar Sarovar Dam: built on the Narmada in Gujarat, covering four states and irrigating drought-prone areas.
• Drawbacks: dams change river flow, cause sedimentation, submerge land, and can even trigger floods and earthquakes.

Rainwater Harvesting Methods Covered in the Class 10 Geography Chapter 3 PDF

Many people saw rainwater harvesting as a better choice than big dams. India has an old tradition of harvesting rainwater, groundwater, and flood water in ways that suit the local land. This is a favourite match-the-column question in the board paper.

In Gendathur, a village in Mysuru, Karnataka, nearly 200 households built rooftop systems. Tamil Nadu is the first state to make rooftop rainwater harvesting compulsory for all houses. In Meghalaya, a 200-year-old bamboo drip irrigation system still taps stream and spring water using bamboo pipes.

Government Schemes for Water in the Water Resources Class 10 PDF

The chapter lists the major water schemes of the government. These are short, fact-based points that often appear as 1-mark or 3-mark questions in the board exam.

• Jal Jeevan Mission (JJM): aims to give every rural household 55 litres of piped water per person each day.
• Atal Bhujal Yojana: works in water-stressed gram panchayats to shift people from water use to water conservation.
• Pradhan Mantri Krishi Sinchayee Yojana: brings protective irrigation to farms with the goal "har khet ko pani" and "per drop more crop".

Important: the goal of all three schemes is the same. They want to conserve water, secure food, and protect natural ecosystems from over-use and mismanagement.
