In the thesis, we analyse generation and characteristics of ship-induced waves in various sailing conditions. These waves, classified as the primary and the secondary, depend particularly on the type of vessel, sailing speed, hull geometry and the distance between the sailing line and the measurement point. The maximum wave heights occur along the two cusp locus lines, where the transverse and diverging waves meet. We questioned the validity of the Bhowmik equation for calculation of the wave heights. The equation depends on pre-defined parameters and can only be used by considering numerous assumptions. Knowing the maximum wave height, we can define the energy of every wave in the wave train per unit area and further calculate the total amount of energy produced from the ship waves. To estimate the bank erosion and damage to the water structures we analyse two key parameters: the wave period and the wave length, which depend on water depth. We calculated the wave periods and wave lengths for two typical cargo ships in deep and intermediate-depth water. A phenomenon called “squat” often occurs in navigation channels and in shallow water. It is a combination of ship sinkage and trim over the bow or the stern due to non-uniform pressure distribution and navigation in shallow water. For navigation channels of simple geometric we show a simple procedure for calculating the ship's sinkage.
