Soil and Water Erosion

Subtopic: Soil loss estimation

Question Statement:

In the Universal Soil Loss Equation ($A = R \cdot K \cdot LS \cdot C \cdot P$), the parameter values are: $R = 250$, $K = 0.30$, $LS = 1.5$, $C = 0.20$, and $P = 0.60$. The estimated annual soil loss $A$ (in t/ha/yr) is:

Answer Key:

13.5

Step-by-Step Solution & Explanation

$A = R \cdot K \cdot LS \cdot C \cdot P = 250.0 \times 0.3 \times 1.5 \times 0.2 \times 0.6 = 13.50\text{ t/ha/year}$
