Rivulay | Dr. Cyndi Vail Castro

Rivulay is a channel about coupled human-water systems — why our best water solutions keep failing, and the science (socio-hydrology) that explains why. Humans aren't just managing the water cycle. We're inside it.

I'm Dr. Cyndi Vail Castro - licensed civil engineer and socio-hydrological scholar.

I've spent the past 15+ years designing and managing real-world water infrastructure across the globe, while simultaneously researching the human-water systems shaping the biggest water challenges of our time. 

Rivulay explores how water and society co-evolve — and why that relationship defines the future of water risk, infrastructure, and policy.
