Q291. Consider the following statements regarding the Indira Gandhi Canal: I. Its origin is from the Harike Barrage situated at the confluence of the Satluj and Beas rivers. II. It was originally known as the Rajasthan Canal until its name was changed in 1984. III. The project has led to a major agricultural green revolution in the Thar Desert. Which of the above statement(s) is/are correct?
Explanation
The Indira Gandhi Canal Project is a multi-state venture originating from the Harike Barrage. Renamed in 1984, it transformed the arid landscape of the Thar Desert into productive agricultural land. By providing a perennial water supply, it facilitated a green revolution, enabling the cultivation of diverse crops and significantly improving the socio-economic conditions and food security of the region.

Q292. The total length of the Indira Gandhi Feeder Canal, from its origin to its entry into Rajasthan at Masitawali Head, is approximately:
Explanation
The Indira Gandhi Feeder Canal is the initial segment of the massive irrigation project, designed specifically to transport water without allowing any intermediate withdrawals. It starts at the Harike Barrage in Punjab and travels approximately 204 kilometers before entering Rajasthan at Masitawali Head. This feeder ensures the efficient and rapid delivery of water to the main canal distribution system.

Q293. Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). Examine the statements and select the correct answer from the options: Assertion (A): The Indira Gandhi Canal has transformed the desert ecology of western Rajasthan and ushered in an agricultural green revolution. Reason (R): The introduction of intensive canal irrigation in the desert has completely eliminated the threat of soil salinity and waterlogging.
Explanation
While the Indira Gandhi Canal has revolutionized desert agriculture and ecology, it has also introduced significant environmental challenges. Intensive irrigation in regions with poor natural drainage has led to rising water tables. This phenomenon causes widespread waterlogging and soil salinity, often referred to as the ‘Sem’ problem, rather than eliminating it, which can eventually render agricultural land completely unproductive.

Q294. Identify the odd one out among the following lift canals based on their association with the Indira Gandhi Canal Project:
Explanation
The Indira Gandhi Canal Project features several lift canals, such as Kanwar Sen and Panna Lal Barupal, designed to irrigate elevated desert lands. In contrast, the Bhikhabhai Sagwara Canal is a distinct irrigation project located in southern Rajasthan. It is designed to utilize the waters of the Mahi River to benefit the tribal-dominated Dungarpur district through traditional gravity flow.

Q295. Consider the following statements regarding the phases and features of the Indira Gandhi Canal Project: I. Phase I of the project primarily covered Ganganagar, Hanumangarh, and parts of Bikaner districts. II. Phase II of the project was designed to extend irrigation up to the Jaisalmer and Barmer districts. III. The main canal provides gravity flow irrigation exclusively to the left side of the canal. IV. The terminal point of the canal system was extended to Gadra Road in Barmer. Which of the above statement(s) is/are correct?
Explanation
The Indira Gandhi Canal Project was executed in two major phases to systematically extend its reach across the desert. Phase I focused on the northern districts, while Phase II reached the deep west. While the main canal provides gravity flow to the right side, lift canals serve the left. The project’s terminal point was eventually extended to Gadra Road.

Q296. Read Statement I and Statement II carefully and choose the correct option: Statement I: All the branches of the Indira Gandhi Canal take off from the right bank, with the exception of the Rawatsar branch. Statement II: The general slope of the land in the command area is towards the left bank, making right bank branches difficult to construct.
Explanation
Most branches of the Indira Gandhi Canal take off from the right bank because the natural land slope facilitates gravity flow in that direction. The Rawatsar branch is the notable exception, originating from the left bank. Contrary to certain misconceptions, the general terrain slope is towards the west and south, making right-bank distribution more feasible for irrigation across the command.

Q297. Which river system provides the continuous water supply required for the Indira Gandhi Canal?
Explanation
The Indira Gandhi Canal relies on a perennial supply of water diverted from the Satluj and Beas rivers. This water is collected at the Harike Barrage in Punjab. This reliable source is crucial for sustaining the extensive irrigation network across the arid Thar Desert, where local rainfall and seasonal rivers are insufficient to support intensive modern agricultural activities and human settlements.

Q298. Match List I with List II and select the correct answer using the codes given below:
Old Name of IGNP Lift Canal
New Name
A. Bikaner-Lunkaransar Lift Canal
i. Dr. Karni Singh Lift Canal
B. Gajner Lift Canal
ii. Panna Lal Barupal Lift Canal
C. Kolayat Lift Canal
iii. Kanwar Sen Lift Canal
D. Phalodi Lift Canal
iv. Guru Jambheshwar Lift Canal
Explanation
Several lift canals of the Indira Gandhi Canal Project were renamed to honor prominent figures. The Bikaner-Lunkaransar canal became the Kanwar Sen Lift Canal. The Gajner canal was renamed Panna Lal Barupal, while the Kolayat and Phalodi canals were renamed Dr. Karni Singh and Guru Jambheshwar lift canals, respectively. These canals are vital for providing water to elevated desert regions.

Q299. Consider the following districts of Rajasthan: I. Bikaner II. Jaisalmer III. Churu IV. Hanumangarh V. Udaipur Which of the above districts benefit directly from the Indira Gandhi Canal Project network?
Explanation
The Indira Gandhi Canal network is a massive infrastructure project benefiting several arid districts. Bikaner, Jaisalmer, Churu, and Hanumangarh receive significant water for irrigation and drinking. However, Udaipur is located in the hilly southern part of the state and falls outside the command area of this canal system, relying instead on local rivers and different southern irrigation projects.

Q300. Which of the following is considered the longest lift canal of the Indira Gandhi Canal Project?
Explanation
The Kanwar Sen Lift Canal is recognized as the longest among the lift canals of the Indira Gandhi Canal Project. It was formerly known as the Bikaner-Lunkaransar Lift Canal. This engineering marvel was named after the visionary engineer who first conceived the idea of bringing Himalayan waters to the Rajasthan desert, playing a pivotal role in the entire project’s technical development.

Key facts from Rajasthan Geography
The RPSC syllabus lists Rajasthan’s location, extent and physiography, rivers and lakes, climate, vegetation, biodiversity, soils, agriculture, livestock, irrigation, population, urbanisation and tribes.
Many questions ask for a number or a name: the area of the State, a district’s density, the length of a canal, the home district of a mine.
Rajasthan is the biggest State of India by area, and several chapters test the contrast between the arid west and the humid south-east.
Minerals, irrigation and wildlife are the chapters with the most name-based questions, so keep a list of districts and projects.
Population questions use Census 2011 figures.
