... coefficient of the ship in long waves, i.e. wave-ship length ratio above 0.7, is provided by a program using 3-D time-domain Rankine panel method, because the power spectrum density is relatively low in long waves at the actual sea. With the numerical results in long waves and the data of the bulk carrier...

... to wave group and breaking (Longuet-Higgins and Stewart, 1962; Symonds et al., 1982; Schäffer, 1993). Many studies found that the nearshore IG waves were combinations of bound long waves and free long waves (edge wave and leaky wave) (Huntley et al., 1981; Elgar et al., 1992; Okihiro et al., 1992; Herbers...

In conclusion, the numerical analyses based on the 3D Rankine method and CFD are better solution for calculating added resistance in long waves than NMRI formula.

... performance, experimental investigations were carried out on vertical slotted wave barriers. The number of barriers was varied from 1 to 6 and the porosity from 10% to 50%. Wave reflection is measured for a wide range of random waves, specifically focused on long waves. It is found that for relatively long...

Good agreements are obtained and the numerical model is used further to explain the spatial evolution of the skewness for the complete wave focusing process (from...

Further the short time analysis of the wave behavior which was not found even on constant slope beaches helps us to identify the forerunners. INTRODUCTION Our...
