Coastal Ocean and Sediment Transport Research Group (PI:Zhi-Cheng Huang)
This research group focuses on scientific issues related to environmental fluid mechanics, including ocean wave dynamics, nearshore turbulence and surf-zone dynamics, coastal sediment transport, and hydrodynamics of coral and algal reefs. We use modern observing and analysis techniques combining with theories and numerical simulations to study physical processes of small-scale flow motions in the nature ocean environments. In addition to use modern instrumentation to measure flow velocity, surface displacement, and high-resolution topography, we develop new techniques to measure these quantities. We also concern coastal hazards, such as coastal erosion, coastline change, and coastal flooding, which may be significantly enhanced by the sea level rise induced by global warming and climate change in the future. We anticipate that the knowledge learned from studying the nature coastal processes can shed some light on developing strategies to reduce coastal hazards.

Marine Physical Observation Research Group (MPORG) (PI:Hwa Chien)
The main themes lay on the fundamental studies of the physical processes that associated or involved in the interactions on the interfaces between air-sea and land-sea. In the air-sea prospective, we focus on the effects of surface waves, whitecapping and roughness to the characteristics of oceanic boundary layer. And quantitatively investigate the magnitude of gases, heat and momentum exchange between air and sea accordingly. Concerning the land-sea interface, investigation of the processes of terrestrial sediment transport in estuary and coastal waters is emphasized. Based on the hydrodynamics and associated Costal Status Indexes (CSIs) that monitored in coastal ocean, we investigate variability of coastline in Taiwan.
Satellite Remote Sensing Research Group (PI: I.-F. Pun)
Using multiple advanced satellite and autonomous profiling floats, we attempt to investigate the important processes and mechanisms under the topic of air-sea interaction, with specific focus on typhoons. It is because typhoon is one the most destructive nature disasters on Earth. Each year, 20-30 typhoons form and rapidly intensify over the western North Pacific Ocean. It is in part due to tremendous amount of warm water and vast ocean basin. These typhoons constantly threaten a billion of people living in the coasts of East Asia. The main goal of our group is to improve our understanding on typhoon intensification, upper ocean thermal structure, and the impact of climate change.
Surface Hydrology Research Group (PI:Ming-Hsu Li)
Interactions of hydrological processes between surface water and subsurface water are complicated in association with diverse spatial and temporal scales. A comprehensive hydrological, micrometeorological, and flux monitoring site has been operated at the Lien-Hua-Chih experimental watershed for investigating land processes. Developments and applications of hydrgeochemical models are our another important task. With abilities of observing and simulating surface water and subsurface water, several critical hydro-environmental issues, such as hydro-hazards induced by extreme events, climate change hydrological impacts, land-atmosphere interactions, CO2 geological sequestration, contaminated groundwater, have been our research mission to provide better understanding and robust tools.
Tsunami Science Research Group (PI:Tso-Ren Wu)
Our laboratory specializing in simulation of complex hydrodynamic processes, including the precise simulation of the tsunamis, three-dimensional landslide simulation, the simulation of three-dimensional debris flow, bridge local scour under the severe floods, impact from debris flow with boulders and driftwood, multi-scale storm surge flood simulation, and so on. Our laboratory has been the global leader in three-dimensional hydrodynamic modeling. Through the volume of fluid (VOF) method and MPI parallel computation, the complex simulations on the tsunami and flood can be fast accomplished with structures and real topography. Recently, our lab has completed the development on the scour and debris flow modeling. Outstanding students are more than welcome to join us.

Water Informatics & Smart Ecosystems Research Group (PI:Pei-Yuan Chen)
Water is essential in the ecosystem comprising of natural environment and human society. The research interest of the WISE lab is resolving the interdisciplinary problems that require hydrological know-how and also advancing the ecosystem smartly to meet the sustainable development goals, by facilitating the integration of existing data, information, knowledge, wisdom, and tools connecting them. Moreover, we are devoted to establish the mechanism of effectively delivering the tailored scientific results to the end-users and make these benefits a self-steering organism. The WISE lab is especially experienced in climate change adaptation, urban hydrology, and storm water management.
