PARTA
Answer any two full questions, each carries 15 marks. Marks
1 2) Describe brief the temporary adjustments of a Dumpy level? (6)
b) Differentiate between declination and dip. (4)
c) What are the possible errors in levelling? (5)
2 a) Explain the bearing systems used in compass surveying. (5)

b) The following consecutive readings were taken with a dumpy level andaSm_ (10)
levelling staff on a continuously sloping ground on a straight line at a common
interval of 25 m. 0.450, 1.120, 1.875, 2.905, 3.685, 4.500, 0.520, 2.150, 3.205
and 4.485. The RL of change point was250.000 m. Make a level field book and
calculate the reduced levels of points using rise and fall method and also the
gradient of the line joining the first and last point.
3 9) Explain the characteristics of contours with neat sketch. (4)

b) The following bearings were observed on a compass traversing. At what (7)
stations do you suspect local attraction? Find the correct bearings of lines. Find
the true bearings if declination was 12° W.

c) Differentiate between Prismatic compass and Surveyor’s compass (4)
