The object of the study is the undulating structures of the water flow arising in the hydraulic flume. Subject of research: the dependence of the parameters of the undulating structures of the water flow, formed by obstacles in the path of the flow. The purpose of this work is to determine the optimal combinations of parameters of obstacles in river channels that excite undulating disturbances of the water flow suitable for freestyle skiing on rough water. Research methods: an experimental method was used on a laboratory model. In the hydraulic flume, various parameters of the water flow were set, and then obstacles of various configurations were placed in its path and the parameters of the changes in the behavior of the flow excited by them were recorded. The master's thesis consists of an introduction, three chapters and a conclusion. It establishes the regularities between the parameters of obstacles on the way of water flows in river beds (canals) and the parameters of the disturbances of water flows generated by them. For this, a special laboratory stand was developed and produced, and with its help three series of experiments were carried out. These patterns make it possible to assess the possibility of artificially creating undulating structures in river beds (canals) and regulating their parameters. The comparison of the flow parameters in the channels of real rivers and canals with flows in the hydraulic flume was carried out using the Froude hydrodynamic similarity criterion. Thanks to this work, in the future, the organization of the training process in the domestic freestyle on rough water can be simplified, training can become much safer, and the number of accidents can decrease.
