The scour depth D of a river during flood, may be calculated from the Lacey's equation
A. D = 0.47 $$\left( {\frac{{\text{Q}}}{{\text{f}}}} \right)$$
B. D = 0.47 $${\left( {\frac{{\text{Q}}}{{\text{f}}}} \right)^{\frac{1}{2}}}$$
C. D = 0.47 $${\left( {\frac{{\text{Q}}}{{\text{f}}}} \right)^{\frac{1}{3}}}$$
D. D = 0.47 $${\left( {\frac{{\text{Q}}}{{\text{f}}}} \right)^{\frac{2}{3}}}$$
