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.

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.
