What machine learning can and cannot tell us about floods

Floods are shaped by complex and nonlinear interactions between weather patterns, rainfall, soil properties, topography, land cover, and how wet a catchment already is. This complexity is one reason machine learning (ML) is increasingly used in hydrology. ML models can learn patterns from large and complex datasets with many variables.  Early in my PhD, while exploring machine learning models for ...[Read More]

HydroTalks: Prof. Thom Bogaard on Water and Landslides, Early Warning Systems, and IAHS-HELPING Decade

HydroTalks: Prof. Thom Bogaard on Water and Landslides, Early Warning Systems, and IAHS-HELPING Decade

For episode 11 of HydroTalks, we welcomed Prof. Thom Bogaard of Delft Technical University and visiting professor at Kasetsart University, Bangkok. His research explores the intersection of hydrology, geomorphology, ecology, and natural hazards. We discussed his work on understanding how water triggers landslides, improving regional early warning systems, and developing practical solutions that re ...[Read More]

Doing flood frequency hydrology in a non-stationary climate

Doing flood frequency hydrology in a non-stationary climate

A robust estimation of probabilities of extreme floods is the Holy Grail in flood hydrology in view of limited available observations, variability of climate, and complexity of flood generation processes in catchments. Flood frequency hydrology, spearheaded in the past decades by Ralf Merz and Günter Blöschl, offers a powerful toolbox to enhance the reliability of flood probability estimates by co ...[Read More]
