The study is concerned with the problems of propagation of water waves over abrupt bottom discontinuities, where the depth changes from one uniform depth non-zero to another uniform depth finite or infinite. The change of depth extends over an infinite line in space. In the first part, theoretical values of the reflection and transmission coefficients and the corresponding phase shifts have been obtained for waves moving over a step-shaped bottom parallel to the wave fronts. The problem is considered as a boundary-value problem in potential-flow theory. The second part is devoted to the problem of the determination of characteristics of waves propagating over a rectangular submarine channel with vertical sides. A mathematical formulation of the problem as a three-dimensional boundary-value problem is given. Author
