The direction of wavespropagation is perpendicular to the fluid flow path. These waves are categorized in standingoscillatory waves type. In the present study, attention is focused on transverse waves formation in arectangular laboratory flume. The flow path obstructions are wooden rods with height of 0.35 mheight and diameter of 0.025 m. They are screwed on the plexiglass plate covered all bottom oflaboratory flume in the staggered and in-line arrangements and with different intervals of rods. Afterestablishment of the flow when the circular cylinders are submerged, no wave oscillations occur, whenthe water level is reduced slowly, 4 types of surface waves are seen across the laboratory flume. Thecurrent study compares the formation of transverse waves in different arrangements of rods. Themaximum wave amplitude observed during experiments was 43% of mean flow depth.}, keywords = {}, title_fa = {تشکیل امواج عمود بر جریان ناشی از موانع استوانه ای در مسیر مجاری روباز}, abstract_fa = {}, keywords_fa = {}, url = {https://jhyd.iha.ir/article_85511.html}, eprint = {https://jhyd.iha.ir/article_85511_36e8b0c98fc90c482ef268f9b658ae51.pdf} }
