What is a catch-can test primarily used to measure?

Accepted Answer

Precipitation rate and distribution uniformity

Answer

A catch-can test measures precipitation rate and distribution uniformity by collecting sprinkler output in small containers placed around a zone.

Question 2

What is the formula for calculating precipitation rate in inches per hour?

Accepted Answer

96.25 × GPM ÷ area (sq ft)

Answer

Precipitation rate (in/hr) = 96.25 × GPM ÷ area in square feet, converting flow to an application depth.

Question 3

A water audit yields a distribution uniformity of 0.62. This result indicates the system is:

Accepted Answer

Poor and should be improved

Answer

A DU of 0.62 (62%) is poor; the Irrigation Association recommends a minimum DU of 0.75 for turfgrass systems.

Question 4

What is the most common cause of dry spots in a zone when run time appears adequate?

Accepted Answer

Low distribution uniformity from improper spacing or worn nozzles

Answer

Dry spots despite sufficient run time usually result from poor DU caused by improper head spacing or worn nozzles leaving low-coverage areas under-irrigated.

Question 5

Which US organization offers the Certified Irrigation Auditor (CIA) credential?
