The Suquía River Basin is regulated by the San Roque Dam, which is located in its upper basin. With a basin area of over 1,750 km2 and a mean streamflow of 9.8 m3 s−1, the Suquía is the second river of the Province of Córdoba (Argentina), according to its streamflow. Downstream from the dam, the river, in its middle basin, runs across a mountain area and then through the city of Córdoba. After leaving the city, in its lower basin, it flows for approximately 150 km towards the northeast until its mouth in the Mar Chiquita Lake. Therefore, the Suquía River has an endorheic basin. The San Roque Dam was designed as a multipurpose dam, and its priority uses include flood mitigation, water supply, irrigation and power generation. On its journey through the city of Cordoba, the Suquía River is urbanised with bridges, fords, coastal roads and a flood plain that is used for recreational purposes. Several studies were conducted to estimate extreme basin events. The basin characteristics were determined by both conventional methods and hydrological modelling. The maximum rainfall records arose from the frequency analysis of 21 rainfall stations installed along the basin. From the hydraulic point of view, several studies were conducted to assess the maximum streamflow and levels on its way through the city of Córdoba. An emergency action plan (EAP) has also been developed to cover a potential failure at the San Roque Dam; so, EAP contains maps of different flooding scenarios in the city. Hydrometeorological drought studies were also carried out in the upper basin (San Roque Dam), considering the analysis of precipitation and stream flows series.
