[2] Consider a linear sinusoidal water wave with wave length 120m and 3-m wave height at 30m water depth. (use sea-water density=1025kg/m³) (a) If the measured dynamic pressure amplitude is 8kPa, what is the corresponding submergence depth of the pressure sensor below MWL (mean water level)? (b) If the ratio of minor semi axis to major semi axis of the elliptical particle trajectory is 0.6, what is the corresponding submergence depth z?
