This study presents results of an experimental nature pertaining to a two-dimensional train of free
internal gravity waves generated in a stably stratified pool of water bounded by the four sides of an open tank
and free surface. The drag resistance due to the waves was measured by means of a spring-mass system
connected between the moving mountain model and the winding mechanism of the apparatus. The mountain
model was of particular importance in this study in that it was shaped in such a way that Fourier's transform
could be employed in obtaining solution to the equations of motion. The analysis of the drag coefficient of the
body was based strictly on the geometry of the mountain model. Fourier's analysis was employed to obtain the
displacement of the fluid particle for each velocity variation.
Key words: Density stratification, drag resistance, Fourier's transform, gravity wave, mountain model, stratified atmosphere,
