Shallow Wave Analysis
The program H2OWAVES calculates wave speed, impedance, and wave flux for shallow ocean waves. The following are assumed:
1. The criteria of λ < D/20 is assumed where λ is the length of the wave. 2. The water assumed to be 0°C, where the density (ρ) is 1,000 kg/m. 3. SI units are used. For gravity, g = 9.80665 m/s^2 is used. Formulas Used Wave Speed (m/s): v = √(g * D) Wave Impedance (Mks): Z = ρ * v Wave Energy Flux (W/m): I = (ρ * g * H)^2/(2 * Z) Maximum Possible Length (m): λ = 20 * D HP Prime Program H2OWAVES Code: EXPORT H2OWAVES() Example Input: Depth: 3.2 m Height: 0.49 m Output: Wave Speed: 5.601899678 m/s Impedance: 5601.899678 Wks Wave Flux: 2060.953478 W/m Source: Ingard, K.U.
