Struct WaterAbsorption 

Source 
pub struct WaterAbsorption {
    pub temperature_c: f64,
    pub salinity_ppt: f64,
    pub depth_m: f64,
}
Expand description

Frequency-dependent absorption model using multiple relaxation mechanisms.

Models absorption in water including classical viscous losses and a magnesium sulfate (MgSO₄) relaxation term.

Reference: Francois & Garrison (1982), simplified.

Fields§

§temperature_c: f64

Temperature [°C]

§salinity_ppt: f64

Salinity [ppt (parts per thousand)]

§depth_m: f64

Depth [m]

Implementations§

Source§

impl WaterAbsorption

Source

pub fn new(temperature_c: f64, salinity_ppt: f64, depth_m: f64) -> Self

Create a new WaterAbsorption model.

Source

pub fn freshwater() -> Self

Freshwater (zero salinity) at 20°C, sea surface.

Source

pub fn seawater() -> Self

Seawater at typical ocean conditions (15°C, 35 ppt, 0 m).

Source

pub fn absorption_db_per_km(&self, freq_khz: f64) -> f64

Absorption coefficient [dB/km] at frequency f [kHz].

Uses the Francois-Garrison formula (simplified).
