Tasuku Ishibashi made a protocol presentation visit to the National Meteorological Service. During it, he was received by the Director of the Agency, Dr. Alejandro de la Torre, and by Dr. Yanina Garcia Skabar, Principal Investigator of the PREVENIR Project. During the visit, Ishibashi also held a meeting with members of the Project where he was told details about it and progress to date.
On December 12, 2023, an end-of-year meeting was held with the project researchers in a hybrid manner. At the meeting, presentations were made to highlight the progress and main results obtained in each of the WPs throughout 2023 as well as outline the next steps to follow
One of the objectives of the project is to improve society's capacity to prepare for sudden urban floods, with special focus on the communities most exposed or vulnerable to the occurrence of these events. In that sense, and understanding that educational institutions play a central role in the construction of citizenship and that the knowledge and knowledge built there then impacts the community of which they are part, PREVENIR seeks to work with the educational community of the basin to offer them tools that allow them to address the problem of hydrometeorological events that generate urban flooding, the management of their information in the event of their occurrence and the possible protection measures that can be adopted against the event.
With this objective, during the month of November 2023, nearly 300 copies of the booklet "Guidance for teachers. Flood risk management" were printed. They are being distributed to Buenos Aires schools located in the area of influence of the Sarandí-Santo Domingo Basin.
The following participated in the preparation of this proposal: PREVENIR technical team, Environmental Education technical team, Ministry of Environment, Climate Change technical team, Ministry of Environment, Undersecretariat of Emergencies technical team, Ministry of Security.
Between October 4 and 5, 2023, the seventh edition of the Symposium on Experimental Methods in Hydraulics, Hydrology and Hydrometeorology (ME3H) was held in the City of Córdoba, a scientific and technical meeting that seeks to provide a forum for discussion and analysis. in the field of experimental methods implemented in hydraulics, hydrology and hydrometeorology, ranging from field studies and surveys to research and measurements developed in the laboratory.
In this new edition - which for the first time includes the areas of hydrology and hydrometeorology - it was proposed to strengthen the integration between the different working groups linked to the theme of the Symposium, fueling the exchange of information and experience, promoting the training of human resources and promoting the creation of new national and international interdisciplinary groups (including representatives of academic, research and management institutions) for the execution of different projects that contemplate the mobility of specialists and scholarship holders.
In addition to the presentation of numerous works within the proposed topics, renowned specialists gave keynote talks during the symposium. Among them, Dr. Luciano Vidal – Investigator of the PREVENIR Project – gave the talk titled “PREVENIR: Forecasting and warning of sudden urban flooding events”.
This Symposium was organized by the Faculty of Exact, Physical and Natural Sciences of the National University of Córdoba, the National Council for Scientific and Technical Research (CONICET) and the Ministry of Public Services of Córdoba Provincial Administration of Water Resources of Córdoba.

During 2023, six professionals from the SMN, INA and CIMA/CONICET carried out stays in Japanese institutions participating in the PREVENIR project to develop joint research activities. Each stay in Japan lasted approximately eight weeks and was carried out at the RIKEN Center for Computational Science institute, Osaka University and the ICHARM institute. These exchanges focused on the activities proposed for working groups WP2, WP3 and WP4.
During the first two weeks of the trip, the annual meeting of the PREVENIR project was held, in which visits were made to different Japanese research and operational work institutions, touring the facilities and participating in conferences given by experts in the areas of meteorology, hydrology and disaster risk reduction. In addition, research meetings of the working groups of the PREVENIR project were held, during which the current status and progress of the activities of the different working groups were presented and the steps to follow for the next year of the project were discussed.
Developments in numerical modeling of the atmosphere, hydrology and data assimilation
Engineer Marina Lagos (INA) visited the International Center for Water Hazard (ICHARM), in the city of Tsukuba where she carried out the implementation of the Rainfall-Runoff-Flood (RRI) hydrological model developed by said institution, for the Sarandí basin -Santo Domingo. On the other hand, he visited the RIKEN Center for Computational Science (R-CCS) in the city of Kobe, where he carried out different tests applying data assimilation techniques for the generation of hydraulic-hydrological forecasts based on ensembles. The hydrological forecasts were fed with ensembles of numerical simulations of the atmosphere that allow different precipitation scenarios to be considered, thereby quantifying the uncertainty in the occurrence of precipitation and its impact on flow estimation.
Dr. Paula Maldonado (SMN) and Dr. Juan Ruiz (CIMA/CONICET), carried out a research stay in the data assimilation group of the RIKEN Center for Computational Science (R-CCS), in collaboration with Drs. Takemasa Miyoshi, Arata Amemiya and Shigenori Otsuka. The main objective of this stay is to contribute to the activities of PREVENIR working group 3, whose objective is to develop a data assimilation and numerical weather forecasting system (BDA-NWP) capable of executing in real time using a model high resolution regional atmospheric. Given the current state of the activities of working group 3, the specific objectives of this research stay were to explore the use of a computational domain that includes both basins and its impact on 10-hour forecasts initialized from data assimilation, and address the sensitivity of the BDA-NWP system to horizontal resolution and ensemble size considering a real-time execution context. To carry out these experiments, the Fugaku supercomputer housed in the R-CCS was used.
Developments in nowcasting and precipitation estimation based on remote sensors
Dr. Maite Cancelada (CONICET-SMN) carried out a research stay at Osaka University in collaboration with Professor Tomoo Ushio and Dr. Daichi Kitahara within the framework of the activities of working group 2. The objective was to advance the improvement of the precipitation estimation product based on dual polarization radars. In particular, he focused on continuing the work started by Dr. Kitahara during his stay in Argentina in 2022 in which he generated an algorithm for the estimation of the specific phase differential, a fundamental variable for an optimal estimation of the precipitation rate. The work consisted of validating the estimates made with this new algorithm with observations of accumulated hourly precipitation in a situation of extreme precipitation in the Province of Córdoba. The results were very encouraging for the development of an operational precipitation estimation product with radars in Argentina.
Ms. María Paula Hobouchian (SMN) carried out a work stay at the RIKEN Center for Computational Science and Osaka University to address some challenges related to work package 2. The work plan at RIKEN was supervised by Dr. Shigenori Otsuka and focused on the development of a satellite nowcasting system to improve the nowcasting of heavy rainfall and flash flood events in Argentina. This system integrates the input data from the GSMaP Near Real Time satellite estimation (GSMaP-NRT; Kubota et al., 2020), the nowcasting methodology developed at RIKEN (Otsuka et al., 2016; Otsuka et al., 2019) and the experience at the regional level in Argentina. The work plan at Osaka University was supervised by Professor Tomoo Ushio and Dr. Daichi Kitahara and focused on advancing a rainfall-adjusted satellite precipitation product to improve precipitation estimation in Argentina. The implemented methodology allows correcting existing satellite estimates such as GSMaP-NRT using the network of rain gauges available in real time in the SMN using.
Dr. Aldana Arruti (SMN) spent a stay at the RIKEN Center for Computational Science whose main objective was to adapt the nowcasting techniques developed by Dr. Shigenori Otsuka for meteorological radar data from Argentina. These activities are part of working group 2, which has among its objectives the development of a nowcasting system based on data extrapolation techniques using data assimilation. Different experiments were carried out to study the sensitivity of the parameters of the nowcasting algorithm on study cases associated with intense precipitation in Argentina. On the other hand, different techniques were evaluated to generate an ensemble that allows quantifying the uncertainty of short-term forecasts.

It took place at the National Meteorological Service and was led by María Eugenia Dillon and Carlos Marcelo García. During the day, a series of talks on topics related to remote sensing, precipitation estimation, atmospheric modeling and hydrological modeling were carried out, followed by discussion time to clarify concepts between the different groups. More than 30 people participated in the meeting in person and online, including representatives of all PREVENIR working groups.
During May first days, three workshops were held at Suquía basin along with local governments to test experiences regarding the use of hydrometeorological information monitoring services. At the same time, several meetings were organized with students and teachers from "Escuela Provincial de Corrientes" (City of Córdoba), rural schools like "Ing. Pagliari", "Teniente Sánchez", "Ricardo Rojas" (City "El Durazno") and "Escuela Mariano Moreno" (City "Río Ceballos"). The mail goal was to present PREVENIR to educational communities, while carrying out didactic activities to address the problem of flash floods at the classroom.
A few days ago, Ms. Mutsumi Sato (JICA's PREVENIR Coordinator) and Dr. Yanina García Skabar (PREVENIR's Manager and Director of SMN's Environmental Modeling and Remote Sensing Products) were invited to participate in "Japan Today" program broadcasted by Radio LED. During the show they were able to make a presentation on the main points of the project, its context, the institutions involved and news about activities carried out recently.
Daichi Kitahara is PhD. in engineering, specifically in computing, he is currently oriented to radars. Since April 2022, he has been working at Osaka University (Japan). Regarding PREVENIR, he belongs to the group in charge of developing a quantitative multi-sensor precipitation estimator with high spatio-temporal resolution. It currently estimates precipitation from radar observations. During his stay at SMN, he developed a new processing method for one of the radar variables and discovered that for operational use, it is key to guarantee computational time and stability over a long period of time. Once that is achieved, the accuracy could be improved as much as possible.
