Abstract: | Conclusions The papers presented to the seminar of the Twelfth Congress of the IAHR, on problems relating to the investigation of the hydrodynamic forces which result under the interaction between the flow and the hydromechanical equipment of large dams and other hydraulic structures, differ in their significance and orientation but on the whole they are indicative of definite progress in this field. It is necessary to note: a) the unquestionable value of the data obtained, which deal with the theoretical and experimental investigation of the hydrodynamic loads acting on different types of hydraulic structures [S1, S2, S5, S7, S11]; b) the interesting data from the study of vibrations in structures [S4, S6]; c) the data found for the analysis of the stability of rock-fill dams [S9]; d) the development of certain new construction elements for hydraulic structures [S8, S10]; e) the insufficient knowledge about the problems involved in the modelling of hydraulic phenomena [S3].
