At Urban Hydrologics, we bring strategic insight, visionary frameworks, and decades of global experience to conversations on climate adaptation, urban hydrology, blue–green infrastructure, and nature-based solutions for cities, watersheds, and island environments.
Founded in 2009, Urban Hydrologics emerged early in the global dialogue around watershed-scale climate adaptation and nature-based solutions, water-sensitive urban design, and blue-green infrastructure (NbS/WSUD/SUDS/ABC-Waters). Since then, our work experiences have explored how hydrology, ecology, planning, engineering, and design can be integrated to shape more resilient and livable communities. Cutting-edge professional experience in the tropical island of Singapore, beginning in 2011, provided the opportunity to contribute to pioneering projects and international collaborations advancing nature-based solutions and watershed resilience in rapidly urbanizing tropical regions.
Over the years, this work has evolved into a distinctive transdisciplinary approach focused on coastal watersheds, tropical cities, and island systems across the pan-tropics. Through lectures, keynotes, and conference presentations, we share lessons from practice, research, and global collaboration, highlighting strategies for climate adaptation, blue-green infrastructure networks, and integrated water management.
Urban Hydrologics presentations combine analytical frameworks, visual storytelling, and real-world case studies to engage audiences ranging from universities and community organizations to government agencies, international conferences, and private sector leaders. Our goal is not only to share knowledge, but to inspire new ways of thinking about water, ecology, and the future of resilient urban landscapes.
We are honored to contribute to global conversations on climate resilience and the stewardship of urban watersheds. Organizations interested in inviting Urban Hydrologics for lectures, keynote talks, or workshops are welcome to reach out.
