Abstract: Information, on behaviour of discharging structures and other control released facilities under extreme hydrodynamic loads, are very important in seeking optimal solutions which will assure their safe and reliable operation. That is a reason for presentation of the extensive investigations of the bottom outlet, located on Yugoslav part of the Hydro Plant “Iron Gate I.” The main purpose of the field tests was to obtain the necessary data for judgment of possibility to use the bottom outlets also as reliable flood discharging structures. The paper considers the hydrodynamic characteristics of flow along bottom outlet, as well as behaviour of the control gate for different operating regimes and reservoir water levels higher than designed one. On the basis of test results: dynamic pressures acting on the control gate, bottom outlet and stilling basin walls; vibrations of gate and concrete structure; lowering and lifting force etc., it was possible to conclude that under some definite conditions, the bottom outlets can be used for passing floods up to the maximum water level in reservoir.
