The Ibero-American Water Journal | RIBAGUA plays a unique role in helping researchers, engineers, and stakeholders in the region communicate their work in Spanish and Portuguese and focuses on topics of interest to the continent.

Issue 1 of 2023 contains four articles on various topics of importance in Latin America. The first one, from Peru, presents experimental research related to vortices that may occur in water intakes, with important applications in dams. Criteria are provided to classify the types of vortices, and conditions to prevent them are analyzed. In the second article, the practical problems of measuring head losses caused by screens in large dams are discussed. In particular, the case of Salto Grande is introduced, between Argentina and Uruguay (the article comes from the latter country), which contributes significantly to the generation of energy in the Southern Cone. Third, a detailed comparison of data models based on precipitation-runoff processes is described, and the performance of models is exemplified with cases from basins in Uruguay. The work is of utmost importance for all basins of Iberoamerica. Finally, a novel methodology to track the effects of COVID-19 on wastewater from the City of Buenos Aires, Argentina, is explained in the fourth manuscript. It was developed by AySA, Aguas y Saneamiento Argentinos without the assistance of any private company, making the technology available.
