by

1 Answer

Answer :

1. Differential leveling is adopted when

i. The points are at a great distance apart.

ii. The difference of elevation between the points is large.

iii. There is obstacle between the points.

iv. The elevations of various points in the area of interest are required.

2. Reciprocal leveling is adopted when the leveling operation is to be continued across the river or valley as it is not possible to place the level midway between two points on opposite banks.
