The case of application was the La Guardia creek, located in the road that communicates the cities of Barquisimeto-Quíbor, Venezuela. The first phase of the study consisted in the comparison of the models from the conceptual point of view and the management of both. The second phase focused on the case study, and the comparison of the results obtained from the hydraulic analysis. It was observed that the behavior in both models presented great similarity in the flow profile as in the regime. Upstream of the two bridges predominate the subcritical regime, where the highest depths and the lowest velocities are present. The opposite occurs downstream of the two bridges, where the supercritical regime prevails, high speeds and minimum depths. It is concluded that, for rivers with simple geometry and preferably with a single bridge, the Hec-RAS one-dimensional software is presented as the best alternative of use due to the ease of data entry, providing reliable results in a shorter time. While the IBER package is two-dimensional, it represents a better option for modeling rivers with more irregular geometries, when there is a special interest in the hydraulic behavior of the flow through stirrups and stacks, and having two or more bridges with separation reduced. Este trabajo tiene como objetivo realizar un análisis comparativo entre los modelos Hec-RAS e IBER, en la evaluación hidráulica de ríos con estructuras como son los puentes. El caso de aplicación fue la quebrada La Guardia, ubicada en la vía que comunica las ciudades de Barquisimeto-Quíbor, Venezuela. La primera fase del estudio consistió en la comparación de los modelos desde el punto de vista conceptual y del manejo de ambos. La segunda fase se enfocó en el caso de estudio, y la comparación de los resultados obtenidos del análisis hidráulico. Se pudo observar que el comportamiento en ambos modelos presentó gran similitud en cuanto al perfil del flujo como en el régimen. Aguas arriba de los dos puentes predomina el régimen subcrítico, donde se presentan las profundidades más altas y las velocidades más bajas. Lo contrario ocurre aguas abajo de los dos puentes, donde predomina el régimen supercrítico, las velocidades altas y las profundidades mínimas. Se concluye que, para ríos con geometría simple y preferiblemente con un solo puente, el software unidimensional Hec-RAS se presenta como la mejor alternativa de uso debido a la facilidad en la introducción de datos, proporcionando resultados confiables en un menor tiempo. Mientras que el paquete IBER por ser bidimensional, representa una mejor opción para modelaciones de ríos con geometrías de mayor irregularidad, cuando se tiene especial interés en el comportamiento hidráulico del flujo a través de estribos y pilas, y al tener dos o más puentes con separación reducida.
