Sprinkler Catch Can Calculator

Measure application rate and low quarter distribution uniformity.

Open this tool

Catch cans show how much water reaches different parts of an irrigated area.

Use equal cans spread across the area and enter the collection duration. Compare application rate and the low quarter result.

Inputs and controls

Catch can test duration

Test duration and target · minutes

Allowed range: 0.01 to 1440

Desired average depth

Test duration and target · mm

Allowed range: 0 to 10000

Can label

Measured catch depths

Caught depth

Measured catch depths · mm

Allowed range: 0 to 1000

How to use

Why use this tool

Measured collection gives a practical basis for reviewing distribution rather than assuming each spot receives equal water.

Before relying on the result

Use equal cans spread across the irrigated area. Low quarter uses the lowest ceil(n/4) cans, stated explicitly.

Tool limitations

Use equal cans spread across the irrigated area. Low quarter uses the lowest ceil(n/4) cans, stated explicitly.

Questions

Which cans form the low quarter?

The calculation uses the lowest rounded up quarter of the can count, with the convention stated in the result.

What should I check before using Sprinkler Catch Can Calculator?

Check Catch can test duration, Desired average depth, Can label and Caught depth. Use the exact units shown beside the controls and replace any example values with your own inputs.
