Question 1

When designing a sprinkler irrigation system, what is the recommended minimum overlap of the spray patterns to ensure uniform water application under standard wind conditions?

60% of the sprinkler wetted diameter 20% of the sprinkler wetted diameter 40% of the sprinkler wetted diameter 80% of the sprinkler wetted diameter

Correct Answer:

60% of the sprinkler wetted diameter

Question 2

Which of the following field conditions is a prerequisite for using the auger hole method to determine soil hydraulic conductivity?

A shallow water table must be present The soil must be completely dry and unsaturated The ground surface must be completely flat A confining clay layer must be present directly below the root zone

Correct Answer:

A shallow water table must be present

Question 3

What is the typical range of soil water tension (suction) at field capacity for agricultural soils ranging from sandy to clay loam?

-0.1 to -0.33 bar 0 to -0.05 bar -1.0 to -2.0 bar -15 bar

Correct Answer:

-0.1 to -0.33 bar

Question 4

In the Rational Formula for peak runoff estimation (Q = CIA/360), what do the variables and the constant represent in SI metric units?

Q is peak discharge (m3/s), C is runoff coefficient, I is rainfall intensity (mm/h), A is watershed area (ha) Q is total volume (m3), C is drainage coefficient, I is infiltration rate (mm/h), A is watershed area (m2) Q is peak discharge (m3/min), C is canopy interception, I is cumulative rainfall (mm), A is area (ha) Q is peak discharge (L/s), C is clay content percentage, I is irrigation depth (mm), A is field area (ha)

Correct Answer:

Q is peak discharge (m3/s), C is runoff coefficient, I is rainfall intensity (mm/h), A is watershed area (ha)

Question 5

In the Universal Soil Loss Equation (USLE), what does the cover-management factor (C) specifically represent?

The ratio of soil loss from land cropped under specified conditions to that from clean-tilled, continuous fallow The ratio of soil loss from a given slope length to that from a 22.13-meter slope length The total kinetic energy of a storm multiplied by the maximum 30-minute rainfall intensity The ratio of soil loss with a specific support practice to that with straight-row farming up and down slope

Correct Answer:

The ratio of soil loss from land cropped under specified conditions to that from clean-tilled, continuous fallow
