From droughts to floods: challenges and opportunities in studying transitions between hydrological extremes
Talk by Eduardo Muñoz Castro, civil engineer and doctoral researcher in hydrology, water resources and climate change.

Megadrought and intense rain: how to anticipate floods
Chile faces a megadrought and ever more intense rainfall. Anticipating the storms takes better monitoring, models and forecasting.

Three students win the ANID National Master's Scholarship
Jocelyn Lugo, José María Araya and Catalina Ferrara, with theses on water resources, climate change and artificial intelligence.

Students study the water supply of Robinson Crusoe Island under climate change
The results show lower water availability, which makes it harder for the island and its residents to adapt to climate change.
