Formula

Overflow = Math.max(0,initial+inflow-capacity); Final = Math.max(0,Math.min(capacity,initial+inflow)-withdrawal); Unmet = Math.max(0,withdrawal-Math.min(capacity,initial+inflow))

How to use this tool

Enter the measured quantities and your own planning assumptions.
Review all calculated outputs and the stated limitations.

Try this example

{
  "capacity": 1000,
  "initial": 300,
  "inflow": 900,
  "withdrawal": 500
}

Accuracy and scope

Assumes all inflow happens before withdrawal. No water-quality or potable-use assessment.
