What Is This Tool?
This tool converts flow measurements from acre-foot per year to US gallon per day, helping users translate large annual water volumes into daily flow rates used in various water management applications.
How to Use This Tool?
-
Enter the flow value in acre-foot per year you wish to convert
-
Select acre-foot/year as the input unit and gallon (US)/day as the target unit
-
Click the convert button to get the equivalent flow in gallons per day
-
Review the result to aid water planning or reporting tasks
Key Features
-
Precise conversion from acre-foot/year to gallon (US)/day
-
Supports water resource management and irrigation use cases
-
Browser-based and simple to operate
-
Provides conversion results based on established rates
-
Includes example calculations for quick reference
Examples
-
Convert 2 acre-foot/year to gallon (US)/day results in approximately 1785.49 gallons per day
-
Convert 0.5 acre-foot/year to gallon (US)/day equals about 446.37 gallons per day
Common Use Cases
-
Planning and managing reservoir release rates in water-resources projects
-
Allocating surface-water and irrigation rights for agriculture
-
Forecasting municipal or regional water supply demands
-
Reporting daily household water consumption in US units
-
Assessing groundwater yields, small pumping tests, and leak rates
-
Calculating chemical dosing rates in water treatment facilities
Tips & Best Practices
-
Ensure the input flow rate represents an annual average for accuracy
-
Use the tool for translating large yearly volumes to daily values for reporting
-
Remember the conversion assumes steady flow over a year; adjust expectations for seasonal variations
-
Apply results thoughtfully in water resource planning and irrigation scheduling
Limitations
-
Conversion is based on a steady flow evenly distributed over one year
-
Actual flow may fluctuate seasonally or daily beyond this assumption
-
Temperature and density changes of water do not affect this volumetric conversion
Frequently Asked Questions
-
What does one acre-foot per year represent?
-
It is a flow rate corresponding to one acre-foot volume delivered over a year, with one acre-foot being the volume covering one acre to the depth of one foot.
-
How many gallons per day equal one acre-foot per year?
-
One acre-foot per year equals approximately 892.75 US gallons per day.
-
Can this conversion account for seasonal water flow variations?
-
No, the conversion assumes a constant flow rate evenly distributed across the year and does not reflect seasonal changes.
Key Terminology
-
Acre-foot/year
-
A flow rate describing one acre-foot of water volume delivered evenly over one year.
-
Gallon (US)/day
-
A volumetric flow rate unit indicating one US liquid gallon passing a point per day.
