TerraEvidence
Measured watering runtime and volume

Measure the installed zone, then calculate what its runtime represents.

Use an isolated flow-meter or bucket-test measurement to calculate total volume, target runtime, or geometric equivalent depth. A dedicated soaker-hose pathway records the tested setup and keeps total delivery separate from distribution.

Step 1 · required

Flow and runtime

Use a flow you measured at the tested setup, or enter a value from another clearly identified source.

Required to calculate: target or runtime, measured flow, flow source, and tested system.

Add optional area, rainfall, or comparison details
Step 2 · optional

Area and equivalent depth

Enter the area receiving the calculated volume, or import area from compatible Garden Bed Builder dimensions saved on this device.

Only length, width, and units are imported. Crop and location fields are not copied.
Step 3 · optional

Recorded rainfall

Add a rainfall depth only when it applies to the same entered area and time record.

Step 4 · optional

Independent volume check

If another method measured total volume, compare it with flow × runtime. A difference is not a diagnosis.

Save or export your water records

Nothing is saved until you choose Save private record. Saved records and optional Garden Subject links stay in this browser and are not placed in a URL or sent with analytics. A profile organizes records; it does not establish watering need or cause. Browser storage can be cleared, so a downloaded JSON backup is the user-controlled durable copy.

No account required

Backup tip: Save at least one private record before downloading. On iPhone, use Share → Save to Files; opening the JSON preview alone does not restore it. Restore this Garden Water file with the Restore JSON backup control on this page.

University-guided method

Measure total delivery and distribution separately.

New Mexico State University supports isolated-zone meter readings and flow calculated from volume divided by elapsed minutes. Texas A&M warns that porous soaker hose can have poor uniformity. Michigan State University evaluates distribution at comparable locations along a system.

TerraEvidence therefore keeps whole-zone total flow separate from beginning, middle, and end observations.

Transparent formulas

Total volume = measured flow × runtime. Runtime for volume = target volume ÷ measured flow. Runtime for geometric depth = area × depth ÷ measured flow after exact conversion.

No plant-need, efficiency, infiltration, soil-storage, or hidden safety factor is applied.
