Studying Ecohydrology across scales


Yin-Phan Tsang

tsang_yin-phanI am an ecological modeler with a great interest in linking hydrology with ecosystems using multidisciplinary approaches. I investigate surface and subsurface water processes and their implication in fluvial ecosystems. I use varied statistical and modeling techniques to combine disparate spatial and ecoinformatics datasets, validated with field measurements, to describe complex interaction patterns between biotic and abiotic processes contributing to ecosystem services. I build ecological predictive models to better address fluvial habitat degradation under anthropogenic and climate change. Knowing the interaction between ecosystems and their adjacent environments is not only a profound knowledge itself and is informative to policy makers and natural resources managers in order to conserve sustainable water resources and to preserve functional aquatic ecosystems. My ultimate goal is to advance our knowledge to achieve a balance between development and sustainable ecosystems.

I am a postdoc in the Department of Natural Resources and Environmental Management at UH. My research here focuses on the impacts of changing climate on Hawaii’s aquatic ecosystems.

My background is in wetland hydrology, biogeochemistry and ecology. My research interests focus on advancing the understanding of hydrological processes (e.g. surface water-groundwater interactions) in wetland environments, and their consequences on ecological functioning, including: the influence of differing hydrological regimes on wetland species, nutrient cycling in stream sediments and riparian zones, and the assessment of anthropogenic pressures (e.g. river engineering, climate change) on wetland health.

During my post-graduate studies and work as a research scientist I have been involved in a number of diverse multidisciplinary water research projects, ranging in scope from large arctic glacial rivers to small temperate streams. My master’s research addressed the importance of river hydrology and flooding for regulating floodplain biogeochemistry. My Ph.D. assessed the significance of enhancing surface-subsurface interactions, i.e. hydrological connectivity via river restoration (embankment removal), on floodplain functioning. I am interested in the use of physically-based hydraulic and hydrological models to simulate wetland processes and anthropogenic disturbances on floodplain ecosystem services (e.g. flood water storage, biodiversity, and water quality), which can provide a quantitative framework to guide the protection and management of water environments.

Hi! I’munnamed Yu-Fen, “your friend”, from the Earth.  I’m currently a Ph.D. student Natural Resources and Environmental Management in the Univeristy of Hawaii in water resources influenced by changes, rainfall-runoff, streamflow and its ecosystem, and maybe sediment transport and fluvial geomorphology.

brendanI am a M.S. student in the Department of Natural Resources and Environmental Management at the University of Hawai’i at Manoa. My research interests encompass stream ecology, hydrology, and water quality. In particular, I am interested in investigating the connections between land-use practices, hydrology, and stream community composition.

Aloha mai kakou! I was born and raised in Honolulu, Hawai‘i and am now a M.S. student at the University of Hawai‘i at Mānoa in the Natural Resources and Environmental Management department. I am currently studying stream restoration efforts on the Winward side of O‘ahu. I have collectively taught and tutored various subjects to different age groups for approximately three years and hope to one day pursue a career in the field of environmental education. Growing up in a place where the conservation of local resources is a pressing issue, one of my goals is to teach future generations about the importance of becoming environmental stewards in Hawai‘i while also serving as ambassadors of the aloha spirit.

I am a M.S. student in the Department of Natural Resources and Environmental Management at the University of Hawai’I at Manoa. My research interests include a focus on watershed analysis using modeling and mapping. I would like to explore ways to use water more efficiently as a resource while minimizing contamination and preserving the environment around it.
