Wave tide water-level combination calculator

Calculate combined levels and maximum supplied scenario level with your own figures.

Your numbers

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

Use combined levels and maximum supplied scenario level to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Calculation method

Calculation method

Combined levels (m)

Add supplied same-datum tide, surge, setup and explicit datum offset; dependence is not modeled.

Maximum supplied scenario level (m)

Maximum arithmetic combined level.

b
Common datum offset (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

  • Supplied tide, surge, setup scenarios. Returns Combined still-water scenarios. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Common datum offset (m): minimum None, maximum 1000000000000.0.
