Answer the following questions:
1.) What is irrigation?
Ans: Irrigation means supply of water to agriculture from canals,wells and tanks artificially or manually.
2.) What are the types of irrigation?
Ans: Based on the source of irrigation it is divided into three types:
A.) Well irrigation
B.) Canal irrigation and
C.) Tank irrigation.
D.)
3.) What is a multi-purpose river valley project? What are its objectives?
Ans: India has undertaken the construction of many river valley projects for the minimum civilisation of river water resources. These projects have other purposes besides providing water for agricultural use. Such projects are called multi-purpose river valley projects. The main aims of these projects are:
A.) Providing irrigation facility,
B.) Production of hydro-electric power,
C.) Prevention of floods,
D.) Creating facility for water transportation,
E.) Providing water for domestic and industrial use,
F.) Preventing soil erosion,
G.) Developing fisheries,
H.) Enhancing forest wealth.
4.) Write a short note on the Bhakra Nangal project.
Ans: India has undertaken the construction of many river valley projects for the minimum civilisation of river water resources. These projects have other purposes besides providing water for agricultural use. Such projects are called multi-purpose river valley projects.
Bhakra Nangal project is the highest multi-purpose valley project of India. This is the joint venture between Punjab, Haryana and Rajasthan state. Dams are constructed at Bhakra and Nangal of Himachal Pradesh across the Sutlej river. The dam at Bhakra is the highest (226 mts) in the project ,it has a canal network of about 3402 kms and provides irrigation to 14.6 lakh hectares. Delhi and Himachal Pradesh have benefitted from this project by way of getting irrigation and hydro-electric power. The reservoir created by this dam is called „Govind Sagar‟.
5.) Name the hydro-electric power projects of Karnataka.
Ans: Shivanasamudra, Tungabhadra, Jog, Bhadra, Alamatti, Kali (Supa Dam) are the hydro electric power projects of karnataka.
6.) ‘Rainwater harvesting is compulsory today’,Why?
Ans: Water is very precious. Although India has vast water resources, it is most unevenly distributed. Rainfall is confined to the rainy season. Even in areas of heavy rainfall, water shortage is seen during the summers. The only solution to the drought condition prevailing in India is „Rain Water Harvesting‟. Collection of rainwater is called “Rain Water Harvesting”.There are two types of water Harvesting :
1.) Collection of water at the place of rainfall. e.g. rooftops of houses and building
2.) Collection of flowing rainwater. For example, building bunds and collecting water.
- Using the water collected from roof tops reduces the dependence on the public water supply.
- Digging ponds in agricultural areas and collecting water.
- Building check dams to prevent the flow of water and allowing it to percolate to increase the ground water table. This is called recharging.
- Not only individuals, even communities can engage themselves in constructing bunds or digging small ponds to collect the rainwater.
In Karnataka, conservation of rainwater has been in practice from ancient times. Tanks, lakes and ponds are all methods of conserving water. Failure to pay attention to these traditional methods has resulted in drought conditions and water scarcity. By protecting and managing properly the water problem in the country can be reduced.
7.) What is the National Power Grid?
Ans: India generates power from various sources. All the states do not have sufficient electric power supply at all times. Therefore, to supply power from surplus states to deficit states, a National Power Grid is established. With its help, excess power from any state can be supplied to any other power deficit state.
