Abstract
    The technique of models with elastic similarity has been adapted for the use in hydraulic models. The problems of dynamic behaviour of structures due to flow turbulence and wave attack are often so complicated that only a model investigation with complete reproduction of the elastic and inertial properties of the gates can be successful.
    Reproduction laws for flow models and for elastic models are derived, and the possibilities for combining the two are shown. The use of elastic models combined with free surface flow and wave motion leads to compromises between elasticity, fluid velocities and geometrical conformity in the elastic model. The verification measurements on the 50 m span gate of the Hagestein weir affirm the reliability of the technique, but show also an important influence of details as seals etc. on the elasticity and damping of the structure.
    Other applications of elastic models of hydraulic structures are shown.
