Groundwater has always had an image problem. Throughout my career, I have lost count of how many times we have described groundwater as an “invisible resource” or similar. It is almost a cliché in hydrogeology. We use the phrase because it captures something really fundamental: groundwater is hidden physically, but it has also been hidden from public consciousness. What people cannot see or easily ...[Read More]

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

Thiruni Thirimanne and Archita Bhattacharyya July 9, 2026

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]
