### Introduction And Calculation Of Elevation With Rise Fall Method With Step

This article is related to finding the calculation of elevation and the introduction and steps of the Rise Fall method. In this method the calculation of land with the help of the rise-fall method. in this method, we calculate the elevation difference between two leveling points during leveling work. must be known about some trick in the calculation.Introduction And Calculation Of Elevation With Rise Fall Method With Step.Introduction Of Rise Fall |Calculation Of Elevation With Rise Fall Method |Step Calculation Of Elevation With Rise Fall Method

After setup leveling machine on the given benchmark then taken Ist reading which is called back sight or Ist Reading. this reading is taken on the benchmark.it is also called B.S

### Inter Sight OR Intermediate Sight

When taken back sight then after taking all reading before Foresight that is called inter sight.it is also called I.S.

This reading is taken when we need to shift the equipment mean level machine. that is called Fore Sight is also called F.S.

### Given level OR Benchmark

This is given level or elevation that is called Bench Mark.it is also called B.M

### Calculate the Rise Fall Formula

1-Back Sight – Inter Sight OR Inter sight – Foresight
B.S – I.S OR I.S – F.S

WHEN

2-Back sight – Fore Sight = +ve means Rise

Backsight – Fore Sight = -ve means Fall

### New Reduced level

New Reduced level = GIVEN R.L – Fall = GIVEN R.L +RISE

### Cross Checking of Arithmetic Calculation

∑Backsight -∑ Foresight = ∑Rise -∑Fall = Last Reduced Level – Ist Reduced level
∑ = means the sum of all
There are all steps to find the Rise and Fall method Calculation.

Example With All Calculation.
