      Development of an efficient two-phase 3D numerical wave flume 

      Frantzis, C.; Grigoriadis, D. G. E. (Society of Petroleum Engineers, 2017)
      In the present study an efficient two-phase 3D numerical wave flume was developed, tested and validated. The most important advantage over conventional numerical wave flumes is the use of a constant coefficient Poisson ...

      How fast are the two-dimensional gaussian waves? 

      Baxevani, Anastassia; Podgórski, K.; Rychlik, I. (2002)
      For a stationary two-dimensional random field evolving in time, we derive the intensity distributions of appropriately defined velocities of crossing contours. The results are based on a generalization of the Rice formula. ...

      Maxima for Gaussian seas 

      Baxevani, Anastassia; Rychlik, I. (2006)
      The probability distribution of the height of global maximum for a Gaussian random field evolving in time is studied. In particular, the effect of spreading is studied and the role of the wave kinematics is discussed. It ...

      Modelling significant wave height in the North Atlantic 

      Baxevani, Anastassia; Rychlik, I.; Wilson, R. J. (2003)
      The surface of the ocean, and so such quantities as the significant wave height, can be thought of as a random surface in space which develops over time. In this paper, we explore certain types of random fields (in space ...

      Relation between velocities and global maximum for Gaussian seas 

      Baxevani, Anastassia; Rychlik, I. (2004)
      We study the probability distribution of the height of global maximum for a Gaussian random field evolving in time. Particularly, we discuss the role of the wave kinematics. It is observed that taking into account time ...

      Spatial models for variability of significant wave height in world oceans 

      Baxevani, Anastassia; Borgel, C.; Rychlik, I. (2008)
      Significant wave height (Hs) is a measure of the variability of the ocean surface. Benefits from knowing the spatial and temporal characteristics of this field are multiple: It is useful to size offshore structures, to ...
