Directional spread parameter at intermediate water depth

摘要: Abstract The characteristics of directional spread parameters at intermediate water depth are investigated based on a cosine power `2s' spreading model. This is wave measurements carried out using Datawell waverider buoy in 23 m depth. An empirical equation for the frequency dependent parameter presented. Directional function estimated Maximum Entropy Method compared with those obtained A set equations relating corresponding to peak spectrum other like significant height and period obtained. It shows that can be related non-linearity parameter, which allows estimation without reference wind information.
