To calculate the Lacey's regime slope, we need to use the formula:

S = (D50)^2 / (8Q^2)

where:
S is the slope of the channel,
D50 is the median particle size of sediment (in mm),
and Q is the discharge (in m3/sec).

Given:
D50 = 0.4 mm
Q = 3 m3/sec

Calculating the Lacey's regime slope:
S = (0.4)^2 / (8 * 3^2)
S = 0.16 / (8 * 9)
S = 0.16 / 72
S = 0.0022

Therefore, the Lacey's regime slope is 0.0022.

Explanation:

1. Lacey's Regime Slope Formula:
S = (D50)^2 / (8Q^2)

2. Given values:
D50 = 0.4 mm
Q = 3 m3/sec

3. Substituting the given values into the formula:
S = (0.4)^2 / (8 * 3^2)
S = 0.16 / (8 * 9)
S = 0.16 / 72
S = 0.0022

4. Therefore, the Lacey's regime slope is 0.0022.

Note: Lacey's regime slope is a measure of the slope required to maintain a stable channel for a given sediment size and discharge. It indicates the minimum slope necessary to prevent sediment deposition or erosion in an alluvial channel of a certain size. In this case, the medium size of sediment particles is 0.4 mm, and the discharge is 3 m3/sec. The calculated Lacey's regime slope is 0.0022.
