Calculate Significant Wave Height from Raw Elevations

Calculates Hs from a time series of surface elevation measurements using the spectral method (4 * sigma).

Usage

calculate_hs_from_elevation(elevations)

Arguments

elevations

Numeric vector of surface elevation measurements (m)

Value

Significant wave height in meters

Examples

# Simulated wave elevation time series
t <- seq(0, 1000, by = 0.5)  # 1000 seconds at 2Hz
elevation <- 0.5 * sin(2*pi*t/8) + 0.3 * sin(2*pi*t/12) + rnorm(length(t), 0, 0.1)
hs <- calculate_hs_from_elevation(elevation)
