“…It uses civil construction materials such as sand, mortar, concrete, steel strips, and bars that require a high effort in their application. Some authors (Olgun, 2013;Ma & Zhang, 2022;Hager et al, 2020) describe how these models are built and the difficulties in their implementation. The development of techniques with modern materials that allow the models to be made more quickly and use less labor specialized in civil construction is a worldwide demand and presents itself as one of the obstacles to the advancement of physical modelling in the coming decades.…”

The study of the interaction between hydraulic structures in mobile bed river systems is complex because it involves sediment transport and dynamic changes in the boundary conditions, requiring the use of physical models. This article presents the procedure for the design and construction of a physical model of the reservoir and dam of the Small Hydroelectric Power Plant (SHPP) of Salto Paraopeba. In the design phase, computational modelling of sediment transport was used to reconstitute the primitive geometry of the river, and simulations of the flow regime and the transport capacity along the course of the river were also carried out; both results allowed to delimit the model extension. Considering the choice of scale and the similarity criteria between the model and the prototype, the use of a new alternative material was proposed, composed of crushed tire rubber particles, with a lower specific mass and a larger diameter than the prototype's sediment. In the construction phase, a new constructive method of the physical model was applied using fiberglass, the method presents constructive advantages, such as better representation of the morphology, lower weight, simple installation and uninstallation through modules, and simple and fast repairs, among others.
