Section 4: Soil and Water Conservation Engineering

Soil and Water Erosion

Subtopic: Terraces and bunds

Question Statement:

For contour bunding on an agricultural field having a uniform land slope of $3.0\%$, the vertical interval ($VI$) between consecutive bunds is calculated using $VI = 0.30 S + 0.60$ (where $S$ is slope in percentage and $VI$ in metres). The horizontal interval ($HI$) between the bunds in metres is ________ (answer in integer).

Answer Key:

50

Step-by-Step Solution & Explanation

1. Vertical Interval ($VI$): $VI = 0.30(3.0) + 0.60 = 0.90 + 0.60 = 1.50\text{ m}$ 2. Horizontal Interval ($HI$): $HI = \frac{VI}{S} \times 100 = \frac{1.50}{3.0} \times 100 = 50\text{ m}$
