CONAGUA 2023

Image
The argentinian national water congress ,  August 28-30, was very dynamic with a lot of young researches. As part of IHLLA , two posters related to flood modelling and discharge time series forecasting with neural networks were presented. The links to the extended abstracts in spanish and bibliography  are here: Flood Modelling with a diffusion wave approximation over FABDEM between Parish and Cacharí. Discharge forecasting with a LSTM neural network applied to Azul basin DB.  

30 years ago in Saragosse

The XIXth International Congress of History of Science was held, what a gift for a recent graduate to see live two nobel prices in Physics: Nikolái G. Básov and Aleksandr M. Prójorov, from the recently dissolute Soviet Union at that moment. After 30 years what can be told nowadays about scientific development and humanity, a brief chronicle is on the way ... 

How is Europe, so far

Many times I'm asked about Europe, here there is a quick answer with a significant plot: European Commission, Directorate-General for Research and Innovation, Hollanders, H., Es-Sadki, N., Regional Innovation Scoreboard 2023 , Publications Office of the European Union, 2023, https://data.europa.eu/doi/10.2777/70412

Please consider to present your research at the first Argentine-Uruguayan Congress of Computational Mechanics, 6-9 th November, Concordia & Salto cities, there is a session about Hydrodynamics and Transport for water bodies . Spanish, Portuguese and English are official languages. Other sites where we can meet and discuss in the short term:   GNSS-IR short course  and  CONAGUA 2023 .

Fresnel zones, testing GNSS-IR

Image
The ground (or water) reflection footprint of GNSS satellites (drawn as Fresnel ellipses) helps to determine how to use that free signal to measure surface water levels, see this remarkable paper by Karegar et al. , a technique already verified to monitor soil moisture, vegetation water content, and snow depth among others, see the multiple contributions pioneered by Kristine M. Larson . The picture shows preliminary tests at Güemes lake , Azul, Buenos Aires province.

Surveys continue with drone footage

Guada´s team in action nearby Cerro del Águila , even in a dry summer. For a deeper detail or high quality pictures check IHLLA sites and publications.  

First drone flight too

At southern hemisphere, with a good GPS cover of 18 satellites. The  UNICEN university campus  at Azul is found at the rear, and at the front many summer pools !
