Soil degree of saturation calculator

Calculate calculated saturation and physical consistency flag with your own figures.

Your numbers

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

Use calculated saturation and physical consistency flag to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Calculated saturation (%)

Saturation fraction = water content fraction × particle specific gravity / void ratio; values above 100% explicitly flagged.

Physical consistency flag

Saturation fraction = water content fraction × particle specific gravity / void ratio; values above 100% explicitly flagged.

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; Saturation fraction = water content fraction × particle specific gravity / void ratio; values above 100% explicitly flagged. 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.
Are these inputs private?

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.
