41. For water waves, this is already the case, as water waves propagate only on the surface of the water. 42. The Boussinesq approximation for water waves takes into account the vertical structure of the horizontal and vertical flow velocity. 43. These tremors have a period which is half of the water wave period and are usually called'secondary microseisms '. 44. The water waves were drawn as overlapping fish scales, the trees look artificial and the figures stood in unnatural poses. 45. The main engineering works performed in 1988 and 1989 featured studies, design, and tests on water wave generation and propagation. 46. He is also the author of the now classic book " Water Waves : The Mathematical Theory with Applications ". 47. Later research and analysis suggested that water waves generated by explosions were different from those generated by tsunamis and landslides. 48. Wave flumes may be used to study the effects of water waves on offshore structures, sediment transport and other transport phenomena. 49. But they make the afterlife seem quite palatable, with these gorgeous babes coming out of the water waving at the camera. 50. Mader applied his expertise in fluid dynamics to research in the numerical modeling of tsunamis ( 1974 ) and other water waves .
