Undesirable vibrations of either structural or technological parts of gated weirs are often observed during the service life of these hydraulic structures. Such vibrations cause inconvenience to the environment due to the induced excessive noise as well as shift the design point of view to fatigue capacity of the appropriate parts. Nowadays, flap gate present the most frequently designed type of gate for weirs in river engineering. Despite their many advantages, such as uniform load of the foundation structure, good regulation of water level, favourable hydraulic properties, when lowered, and most importantly good price to gated head ratio, they suffer from vibration issues. The paper presents results and comparison of in-situ measurements, laboratory experiments and numerical modelling.
