Water Resources Modelling

 On October the 2nd, this is how the surrounding plains of Las Mulitas lagoon at 25th of May village , looked like.     

This is the dike that retains up to 65 Hm3 in such a flat land and keeps safe Azul city when Azul stream raises its levels.         

Principles of Surface Hydrology , with the invaluable drive of professor Erik Zimmermann, recently retired from UNR, and IHLLA colleagues Drs Blanco, Briceño, Holzman, and Ing. Golin. In Spanish, dates 21st-25th April, 2025, promoted by DCAAS-UNCPBA and CADES.    Image: HAND algorithm over FABDEM at Bahía Blanca.

  On March the 7th, the southern cold front brougth the stream close to full discharge capacity, in addition we can observe standing waves in phase with the river bed. But in Bahía Blanca was much worse, to be commented in the next Blog post.

What  a tough year for Argentina, but let me emphasize a few issues for optimism: We´ve been awarded three projects from CFI, FITBA and CIC Buenos Aires public institutions, the first one to design upstream water retention schemes, the second one to include AI on the Azul EWS and the third one to propose drainage and retention soft structures at a plain parcel in direct coordination with the owners, all are measures to gain flood resilience.  Lorena La Macchia MSc thesis dissertation was awarded as the best contribution related to Cartography, Geodesy and Geographic Information in 2024, by the Panamerican Institute for Geography and History . She also received a grant from " Move la America " brasilian program to stay at INPE. The published paper related to Digital Elevation Models in large plains by Ailé Golin et al .                                             ...

Two factors: extreme precipitations (convective cells) and the incapability of the ground/drainage systems to  handle such heavy rainfalls in a short period of time. It´s not the first time, neither the last,  and is still hardly to predict both the focus location and the flash flood evolution. Learning to Live with Risk for each municipality continues as the most reasonable policy, considering that long term climate projections are worse. My condolences for almost one hundred casualties at the moment. Satellite image from RTVE live and ALSOSpace over Valencia. EU-Copernicus Emergency Service Link    for mapping damage extents.
