Q1The Indira Gandhi Canal benefits Rajasthan's desert districts, but its source point lies outside Rajasthan. Which source point is correctly associated with this canal system?
A common CET trap: the Indira Gandhi Canal, earlier called the Rajasthan Canal, benefits Rajasthan but starts from Harike Barrage in Punjab. It brings allocated Ravi-Beas water towards the arid north-west and west of Rajasthan. Kota Barrage belongs to the Chambal command, Bisalpur is a Banas river dam in Tonk, and Mahi Bajaj Sagar is linked with the Mahi basin in southern Rajasthan. The source cue therefore points to Harike Barrage in Punjab.
Q2Assertion (A): In the Indira Gandhi Canal command, lining, drainage, land levelling, controlled irrigation and crop choice are important for sustainable irrigation. Reason (R): In flat arid command areas, weak drainage can raise the groundwater level and increase salinity at the surface. Choose the correct answer.
The Indira Gandhi Canal is treated as both a success in desert irrigation and a command-area management case. In flat arid areas, canal water without proper drainage can raise the groundwater level; in hot, dry conditions, salts can collect near the surface. That risk explains why lining, field drainage, land levelling, controlled irrigation and suitable crop choice are important. The management measures and the drainage-salinity reason are both true, and the reason gives the logic behind the measures.
Q3Read the Assertion and Reason carefully: Assertion (A): The Indira Gandhi Canal created agricultural and settlement opportunities in western Rajasthan, but it did not make the whole desert uniformly green. Reason (R): The benefit of the canal depends on command area reach, branch canals, soil conditions, drainage and regularity of water supply. Choose the correct answer.
The assertion reflects the balanced view. The Indira Gandhi Canal supported wheat, cotton, mustard, fodder, drinking water, settlement and dairy-linked activity in selected command areas. At the same time, one should not imagine the whole desert as uniformly transformed. The reason gives the controlling variables: command reach, branch canals, soil, drainage and regularity of supply decide where the gain is strong and where it remains limited. Therefore the reason is true and explains the assertion.
Q4Assertion (A): In canal command areas, over-irrigation without proper drainage can cause waterlogging and soil salinity. Reason (R): In arid and semi-arid regions, excess water can raise the water table and evaporation can leave salts in the soil.
Large canal irrigation succeeds only when water use, drainage and maintenance are managed. Waterlogging occurs when excess water raises the water table close to the surface. In arid and semi-arid regions, evaporation then leaves salts in the soil, reducing productivity. This is exactly why canal lining, field drainage, controlled irrigation and water-use efficiency are stressed for the Indira Gandhi Canal command.
Q5Consider the following statements about the length structure of the Indira Gandhi Canal system: Statement 1: The Rajasthan Feeder and the Indira Gandhi Main Canal together form a system of about 649 km. Statement 2: The Indira Gandhi Main Canal alone should be stated as about 649 km. Which of the statements is/are correct?
The length trap is precise. The Rajasthan Feeder is about 204 km and the Indira Gandhi Main Canal is about 445 km in total; together they make a canal system of about 649 km. The main canal alone should not be stated as 649 km. Therefore the statement using 649 km for the combined feeder-plus-main system is valid, while the statement assigning the same length to the main canal alone is the common exam error.
