Professor Murugesu Sivapalan shares how the field of hydrology has evolved over the past few decades, on Season 2, Episode 5 of the Water Data Podcast.

Prof Murugesu Sivapalan is the Chester and Helen Siess Endowed Professor in Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign. Dr Sivapalan is an award-winning academic and was founding chair of the International Association of Hydrological Sciences (IAHS) Decade on Predictions in Ungauged Basins (PUB) initiative. His work on Predictions in Ungauged Basins as well as in socio-hydrology have shaped the discipline of hydrology as we know it today.

Host Veena Srinivasan talks to Dr Sivapalan about his rich career of starting out with hydrological modeling, and early explorations into collecting and analysing hydrological data to infer how complex catchment and river basin systems functioned.

Hydrology is the science of the movement, distribution and management of water. Dr Sivapalan walks us through how the ‘Predictions in Ungauged Basins’ decade pushed people to better understand the physical processes around the hydrological cycle, beyond statistical analyses and calibrated models. He shares how catchments co-evolved with the biology they sustained, and how they shaped each other.

Dr Sivapalan goes on to talk about socio-hydrology, and how human activities also shape river basins and water systems, and vice versa. He explores how it is impossible to understand water systems today without paying close attention to human behaviour and human actions.

Host Veena Srinivasan sits down with Dr. Tom Gleeson, renowned hydrologist and Professor at the University of Victoria, Canada.

Dr. Tom Gleeson shares his journey from a small-town experience with groundwater contamination to becoming a global leader in groundwater research. The conversation explores Tom’s early fieldwork in fractured rock aquifers, the challenges of modeling groundwater systems, and his pivotal role in developing global groundwater sustainability frameworks. Tom and Veena discuss the importance of context in water management and the need for both local and global perspectives.

This is Season 2, Episode 4 of the Water Data Podcast, a talk show on the science, systems, and stories of water hosted by Veena Srinivasan. Veena Srinivasan is an award-winning socio-hydrologist as well as the founder and Executive Director of WELL Labs, a water systems research and innovation centre based in Bengaluru, India.

Dr Gleeson also delves into his recent work on community-based watershed monitoring and the power of citizen science, highlighting innovative projects that blend science, policy, and indigenous data governance. The episode concludes with a thought-provoking discussion on integrating art and emotion into science communication, emphasising that real change comes from engaging both the mind and the heart.

How and why does flooding take place? How are flood risks evolving with climate change and large-scale human alteration of riverscapes and watersheds? Does it even make sense to measure a ‘100-year-flood’ any more?

Stockholm Water Prize 2025 winner Dr Guenter Bloeschl shares a masterclass on the science and management of floods on the third episode of Season 2 of the Water Data Podcast. The Water Data Podcast is a talk show on the science, systems, and stories of water hosted by Veena Srinivasan.

Professor Guenter Bloeschl is a hydrologist, engineer and academic from Austria. Dr Bloeschl is Head of the Institute of Hydraulic Engineering and Water Resources Management, Director of the Centre for Water Resource Systems of the Vienna University of Technology as well as Chair of the Vienna Doctoral Programme on Water Resource Systems.

He is also the 2025 recipient of the Stockholm Water Prize, awarded by the Swedish Academy of Sciences and the Stockholm Water Foundation. One of the highest honours in the water sciences, Dr Bloeschl received it for his extensive work on flood risk reduction, water resource management, flood scaling, and regional process hydrology.

In this episode, Dr Bloeschl talks about the science of flooding, what research shows about the evolving causes and impacts of floods in Europe, and flood mitigation and management lessons for India and the world.
