Not just locations, coordinates, and position of things on the earth, there is much more that is discussed in geography. Geography is also concerned with the physical and human aspects of various locations. Geographers study the meaning, function, and history of locations and how they change and are perceived, from the size of a single room to the size of a cultural area or the entire world.
Water resources are the third Chapter in class 10 geography. The water sources, the water shortage, and the problems associated with it will be explored in the NCERT Class 10 Geography Chapter 3. The Water Resources Class 10 Solutions also mentions dams built across rivers. The issue of water conservation will be explored in the Water Resources Class 10 Solutions.

Key Topics Covered in Class 10 Geography Chapter 3
The key topics that are covered in Class 10 Geography Chapter 3 are mentioned below :
- Water
- Multi-purpose River projects and integrated Water Resource Management
- Rainwater Harvesting
Let us look at Extramarks in-depth information on each subtopic in Class 10 Geography Chapter 3.
Water
Class 10 Geography Chapter 3 explains that although water covers three-quarters of the Earth’s surface and is a renewable resource, only a small percentage of it is fresh water that can be used for human consumption. Therefore, water scarcity can be a major issue, despite its abundance.
Water Scarcity and the need for Water Conservation and Management
Water supplies vary in availability throughout time and place.
- Over-exploitation, excessive consumption, and uneven access to water among different socio-economic groups are the causes of water shortage.
- To extend irrigated regions for dry-season agriculture, water supplies are being over-exploited.
- Water is adequately accessible in specific locations to suit the demands of the inhabitants. However, such areas may face water constraints due to poor water quality.
- Post- Independence industrialisation
Class 10 Geography Chapter 3 states that our water resources must be conserved and always managed:
- To protect oneself from health risks.
- To secure food, the viability of our livelihoods, and the continuation of constructive activities.
- To keep our natural ecosystems from degrading.
Multi-purpose River projects and integrated Water Resource Management
Class 10 Geography Chapter 3 explains that humans conserved water by building complex hydraulic structures such as stone rubble dams, reservoirs or lakes, embankments, and irrigation canals in the past. We have perpetuated this practice in modern India by erecting dams throughout most of our river basins.
Dams
Class 10 Geography Chapter 3 explains the concept of Dams in the following section.
A dam is a structure that obstructs, directs, or slows the flow of water, resulting in a reservoir, lake, or impoundment. The reservoir, not the building, is referred to as a “dam.”
Uses of Dams
Class 10 Geography Chapter 3 says that the Dams are constructed for the following uses:
- Impounding rivers and rainfall for later use as irrigation for agricultural lands.
- For the production of electricity.
- Water supply for both residential and industrial use.
- Controlling floods.
- Recreation, inland navigation, and fish spawning are important aspects of inland navigation.
Limitations of creating Dams:
- River regulation and damming have an impact on their natural flow.
- As a result, the ecosystems of aquatic life in rivers are deteriorating.
- Fragment rivers hamper the migration of aquatic animals.
- Dams built on floodplains bury existing plants and soil, resulting in their degradation over time.
- Many new environmental initiatives, such as the ‘Narmada Bachao Andolan’ and the ‘Tehri Dam Andolan,’ have sprung up in response to the construction of big dams.
- For the dam’s construction, local people were forced to give up their land, livelihoods, and control over resources on several occasions.
Class 10 Geography Chapter 3 explains that most of the criticisms of the initiatives came from their inability to fulfil the aim for which they were designed. For example, most dams were built to manage floods, although they have themselves generated floods. Dams have also resulted in significant soil erosion. In addition, excessive water consumption has resulted in earthquakes, water-borne illnesses, pests, and pollution.
Rainwater Harvesting
Class 10 Geography Chapter 3 explains the concept of Rainwater harvesting in the following section.
Rainwater harvesting is a simple way of collecting and preserving rainwater for later use. The rainwater collected can be stored, used in various ways, or used immediately for recharge.
Rainwater harvesting has been done in a variety of ways in different regions.
- People have created diversion channels for agriculture in hill and hilly terrain, like the guls or kuls of the Western Himalayas.
- Rooftop rainwater collection is a prevalent practice in Rajasthan for storing drinking water.
- People created inundation canals in the Bengal flood plains to irrigate their crops.
- Agricultural fields were turned into rain-fed storage structures in dry and semi-arid regions, such as ‘khadins’ in Jaisalmer and ‘Johads’ in other parts of Rajasthan, to allow water to stand and saturate the soil.
- The tankas are erected within the main house or courtyard as part of the well-developed rooftop rainwater gathering system. This is widely done in Rajasthan, notably in the districts of Bikaner, Phalodi, and Barmer, to conserve rainfall. In addition, many homes have built subterranean chambers adjacent to the ‘tanka’ to avoid the summer heat by keeping the space chilly.
Tamil Nadu is the first state in India to make rooftop rainwater collecting structures mandatory for all homes in the state. Defaulters are subject to legal consequences.
