Abstract

The OpenTelemac-Mascaret numerical model was implemented to simulate thermal transport and its interaction with the environment along a 182 km reach of the Uruguay River, between Concepción del Uruguay and Nueva Palmira. The model was calibrated and validated using field data, showing good agreement between simulated and observed temperatures. The results allowed for the characterization of the river’s thermal regime and the evaluation of extreme temperature scenarios, making it a useful tool for predicting thermal alterations and supporting environmental management.
