In this thesis the transformation of the solitary wave in two different processes is discussed from theoretical and practical point of view. The processes are the damping due to bottom friction and the overtopping at a seadike. They have the common feature of subtracting an amount of energy of the wave, although the modes of subtraction are quite different. The effect of the bottom friction to the deformation of the finite amplitude long waves on a horizontal bed, is mathematically modelled by associating the empirical friction term of steady flows with the irrotational, Boussinesq's equations. For the waves travelling in one direction only, the modified Korteweg-de Vriea equation (Kdv equation) is derived. In dimensionless variables, this equation is written as: Nt + NNs + Nsss + B A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Engineering Thesis (Ph.D.) - Asian Institute of Technology, 1975 Waves Asian Institute of Technology. http://203.159.5.9/ait-thesis/detail.php?q=B00395 http://203.159.5.9/ait-thesis/detail.php?q=B00395 141197 20260819085035.0
