If a gauge is installed perpendicular to the slope, its measurement of precipitation may be reduced due to the angle of inclination between the slope and the gauge. The reduction in measurement due to the angle of inclination is known as the slope correction factor.
To calculate the slope correction factor, you can use the following formula:
Slope correction factor = cosine of the angle of inclination
Therefore, the correct answer to the question is (b) cosine of the angle of inclination with vertical.
It is important to note that the slope correction factor only applies to gauges that are installed on a slope and does not apply to gauges that are installed on a horizontal surface. Additionally, the slope correction factor should only be applied if the gauge is installed at an angle that is significantly different from the horizontal. If the gauge is installed at a very small angle, the slope correction factor may be ignored.

Explanation:
When a gauge is installed perpendicular to the slope, its measurement is reduced by multiplying the cosine of the angle of inclination with vertical. This can be explained with the following points:
Angle of Inclination: The angle of inclination is the angle that a slope makes with the horizontal plane. It is measured in degrees or radians.
Perpendicular Gauge: When a gauge is installed perpendicular to the slope, it measures the vertical distance between the gauge and the slope. This measurement is affected by the angle of inclination.
Cosine Function: The cosine function is a trigonometric function that relates the adjacent and hypotenuse sides of a right triangle. It is defined as the ratio of the adjacent side to the hypotenuse side.
Reduction Factor: The reduction factor is the factor by which the gauge measurement is reduced due to the angle of inclination.
Formula: The reduction factor is equal to the cosine of the angle of inclination.
Calculation: To calculate the reduction factor, we need to know the angle of inclination. Once we know the angle, we can use the cosine function to calculate the reduction factor. For example, if the angle of inclination is 30 degrees, the reduction factor would be cos(30) = 0.866. This means that the gauge measurement would be reduced by 0.866 times the actual vertical distance.
Therefore, the correct answer is option 'B', which states that the measurement is reduced by multiplying the cosine of the angle of inclination with vertical.
