Reservoir level-volume interpolation calculator

Calculate interpolated storage volumes JSON with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use interpolated storage volumes JSON to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Surveyed levels (m)
10,11,12
Storage volumes (m³)
0,1000,2500
Query levels (m)
10.5,11.5
Interpolated storage volumes (m³) JSON
[500,1750]

Try another scenario

Surveyed levels (m)
[9, 11, 12]
Storage volumes (m³)
[0, 1000, 2500]
Query levels (m)
[10.5, 11.5]
Interpolated storage volumes (m³) JSON
[750,1750]
Calculation method

Calculation method

Interpolated storage volumes (m³) JSON

Piecewise-linear storage interpolation inside the surveyed stage range; out-of-range queries rejected.

Symbols and units
a
Surveyed levels (m)
b
Storage volumes (m³)
c
Query levels (m)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Piecewise-linear storage interpolation inside the surveyed stage range; out-of-range queries rejected. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
