Question

The sediment yield ($D_r$) of a watershed, which is a function of sediment yield ($S_y$) and gross erosion ($E_g$), is represented by:

• A. $D_r = \frac{S_y}{E_g}$
• B. $D_r = S_y \times E_g$
• C. $D_r = \frac{E_g}{S_y}$
• D. $D_r = E_g + S_y$

Hint:

The sediment yield (Dr) equation helps in assessing soil conservation measures and watershed management strategies.

Answer 1

The Correct Option is A

The sediment yield ($D_r$) is calculated as the ratio of the sediment yield ($S_y$) to gross erosion ($E_g$), considering the sediment delivery ratio of the watershed.
