 Q.1 Assertion(A): Duty is an expression of the irrigation capacity of a unit volume of water.

        Reason(R): Duty at the head of a distributary will be less than that at the head of a watercourse and more than that at the head of a canal.

(a)               (b)                (c)                  (d)

Q.2 The delta for a crop having base period 120 days is 70 cm. What is the duty in hectare/cumec

(a) 2480        (b) 1481          (c) 148        (d) 1.481

Q.3 The CCA for a distributary is 200000000 m^2. The intensity of irrigation for a crop is 40%. If KOR water depth and KOR period for the crop are 14 cm and 4 weeks, respectively, the peak demand discharge (in cumec)

(a) 2.63          (b) 4.63          (c) 8.58        (d) 11.58

Q.4 The two columns below show some parameters and their possible values:

     Parameters                                        Value 

P.        GCA                                          i. 1000 ha/cumec

Q. Permanent wilting point                 ii. 6 degree centigrade

R. Duty of canal water                        iii. 1000 hectares

S. Delta of wheat                                iv. 1000 cm

                                                             v. 40 cm

                                                            vi. 0.12

(a) P-i, Q-ii, R-iii, S-iv

(b) P-iii, Q-vi, R-i, S-v

(c) P-i, Q-v, R-vi, S-ii

(d) P-iii, Q-ii, R-v, S-iv

Q.5 The total irrigation depth of water required by certain crop in its entire growing period (150 days) is 25.92 cm. The CCA  for a distributary channel is 100,00 ha. The distributary channel shall be designed for a discharge

(a) less than 2 cumecs

(b) 2 cumecs

(c) 20 cumecs

(d) more than 20 cumecs
