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 (minutes). Allowed range: 0.01 to 1440
* Desired average depth (mm). Allowed range: 0 to 10000
* Can label
* Caught depth (mm). Allowed range: 0 to 1000

## How to use

* Enter catch can test duration and desired average depth.

* Add the entries in measured catch depths as separate rows. Include can label and caught depth for each row.

* Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.


## 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.
