What is the combined C value for 60% at 0.2 and 40% at 0.9?

What is the combined C value for 60% at 0.2 and 40% at 0.9?

• A. 0.12
• B. 0.36
• C. 0.48
• D. 1.10

Answer: (C)

To determine the combined C value based on the given percentages, you will use a weighted average method. In this case, you have 60% of the area with a C value of 0.2 and 40% with a C value of 0.9. The formula for the combined C value (C_combined) can be expressed as: C_combined = (percentage 1 * C value 1) + (percentage 2 * C value 2) Calculating this: 1. For 60% at 0.2: \( 0.60 \times 0.2 = 0.12 \) 2. For 40% at 0.9: \( 0.40 \times 0.9 = 0.36 \) Now, add these two results together: \( C_combined = 0.12 + 0.36 = 0.48 \) Thus, the combined C value is 0.48. This methodology is effectively a way to calculate the average value considering the different contributions of each land cover type, weighted according to their respective areas. The combined C value reflects a weighted interaction between the two hydrological properties quantified by their contributions

Calculating this:

1. For 60% at 0.2:

( 0.60 \times 0.2 = 0.12 )

2. For 40% at 0.9:

( 0.40 \times 0.9 = 0.36 )

Now, add these two results together:

( C_combined = 0.12 + 0.36 = 0.48 )

Thus, the combined C value is 0.48. This methodology is effectively a way to calculate the average value considering the different contributions of each land cover type, weighted according to their respective areas.
