Calculation of Quantity of Earthwork for Canal Embankment using Trapezoidal Method

Given Data:
- Length of canal embankment = 100 m
- Heights at two extreme edges = 3 m and 5 m
- Top width at two extreme edges = 2 m and 4 m
- Side slope = 2:1

Step 1: Calculation of Cross-Sectional Area of Embankment
- Divide the embankment into equal sections, say 10 sections of 10 m each
- Calculate the heights of embankment at each section with the help of given data
- Calculate the width of embankment at each section with the help of given data
- Calculate the cross-sectional area of embankment at each section using trapezoidal formula:
- Cross-sectional area = [(width1 + width2) / 2] x height

Step 2: Calculation of Total Volume of Embankment
- Calculate the total volume of embankment by adding up the cross-sectional areas of all the sections:
- Total Volume = Area1 + Area2 + ... + Area10

Step 3: Calculation of Quantity of Earthwork
- Calculate the quantity of earthwork by subtracting the volume of excavation from the volume of embankment:
- Quantity of Earthwork = Total Volume of Embankment - Volume of Excavation

Conclusion:
- The quantity of earthwork for the given canal embankment is calculated using trapezoidal method as explained above.
