The author once published the tables of some integrals appearing in some problems of surface-waves. In the present paper, the applications of these tables are showed for some periodic motions that is : (i) Calculations of wave elevation and induced pressure by a periodic point source, (ii) Calculation of flap-type wave generater, (iii) Two-dimensional source distribution for the heaving motion. These examples show the Usefulness of application of periodic source distributions for some problems of surface waves.
