Differentiate between 'H.I. method' and 'Rise and Fall method' with respect to time, checks, application and simplicity. 
by

1 Answer

Answer :

Sr. No.
Point of difference
H.I. method
Rise and fall method
1 Time
Less time required for calculations of RLs.
More time is required for calculations of RLs.
2 Check
Arithmetic check performed is ΣBS - ΣFS = Last RL – 1 st RL. Gives check only of corrections of starting point and last point. Correction of RL of intermediate points is not checked.
Arithmetic check performed is ΣBS - ΣFS = Last RL – 1 st RL = ΣRise – ΣFall. RLs of all points are checked in this method.
3 Application
H.I method is applied for profile leveling, road survey, canal survey, etc.
Rise and fall method is applied for check leveling, fly leveling, etc.
4 Simplicity
More simple, rapid involving less calculation. 
Involves several calculations hence more laborious and time consuming.
