Verified Answer
What will be the value of horizontal equivalent between two points for...
Horizontal equivalent- horizontal distance between two points on two consecutive contour lines for a given slope.
Horizontal equivalent = contour interval x gradient = 9 x 10 = 90 m
Horizontal equivalent = contour interval x gradient = 9 x 10 = 90 m

Understanding Horizontal Equivalent
The horizontal equivalent is a concept used in civil engineering, particularly in surveying and topography, to determine the horizontal distance between two points on a slope.
Given Parameters
- Contour Interval: 9 m
- Upward Gradient: 1 in 10
Calculating the Horizontal Equivalent
To find the horizontal equivalent, we can use the relationship between the vertical rise (contour interval) and the horizontal distance based on the gradient.
1. Gradient Explanation:
- A gradient of 1 in 10 means that for every 10 horizontal meters, there is a vertical rise of 1 meter.
2. Vertical Rise Calculation:
- The vertical rise corresponding to each contour interval is 9 m.
3. Using the Gradient:
- If the rise is 1 m for every 10 m horizontally, then for a rise of 9 m:
- Horizontal distance = 9 m (rise) * 10 (horizontal distance per meter rise)
- Horizontal distance = 90 m
Conclusion
The horizontal equivalent between the two points, considering a contour interval of 9 m and an upward gradient of 1 in 10, is 90 m. Therefore, the correct answer is option 'C'.
This calculation is essential for understanding how elevation changes affect horizontal spacing in construction and land development projects.
