Hydroclimatology Research Group


Welcome to the homepage of the Hydroclimatology Research Group at POSTECH. Please follow the NEWS about our research group activities and visit other web pages: Group Members, Research Projects, Publications, Photos, and Archive.

Hydroclimatology@POSTECH is currently looking for highly motivated graduate applicants.

Potential topics are 1) drought mechanisms, risk, and predictability, 2) large-scale land surface modeling with a focus on anthropogenic processes (dam and irrigation), 3) hydrodynamical modeling with underwater drone-based river bathymetry surveys, and 4) socio-hydrology with a focus on the dynamics of social response (potential triggers and growth and decay patterns) during emerging water-related disasters.

Dr. Kam's paper about global public interest in earthquakes was accepted for publication in Humanities and Social Sciences Communications (Springer-Nature Journal). This work focused on understanding how public interest in earthquakes changes during the emergence of 17 significant earthquakes over the globe, using multiple data sets. We found the Western dominance in the dynamics of global public interest in earthquakes. We also found that there are two weeks after the earthquake occurrence to effectively raise donations, charities, and aid resources for earthquake relief and recovery.


Dr. Kam's paper about northwest Russia was accepted for publication in Bulletin of the American Meteorological Society's special issue of "Explaining Extreme Events of 2020 from a climate perspective" (JIF: 8.8 and Rank: 4/94 (Meteorology & Atmospheric Sciences)). This work focused on understanding how anthropogenic influences affect the record-breaking warm and wet winter 2019/20 over northwest Russia, using the Coupled Model Intercomparison Project Phase 6 (CMIP6).


The proposal, "Multi-scale assessment of drought mechanisms and predictability", was funded by the National Research Foundation of Korea. The goal of this project is to better understand global drought mechanisms and predictability across the spatial and temporal scales through the water cycle. We are seeking postdocs and graduate students who are highly self-motivated. Please contact us if you are interested in this project.


Yena Kim (MS/PhD) and Jiam Song (MS/PhD) join our research group. Welcome aboard!


The proposal, "Impact of the land and terrestrial ecosystem in East Asia on global/local carbon cycle", was funded by the National Research Foundation of Korea. The goal of this project is to better understand the role of land and terrestrial ecosystem over East Asia in the global/local carbon cycle.

This project is a sub-project of "Understanding of East Asia Climate-Carbon Interactions" led by Hanyang University (Lead-PI: Prof. Sang-Wook Yeh). The Participant Institutes are Seoul National University, POSTECH, and Pukyong National University. We are so excited to join this multi-disciplinary research team.


We made the first landing of our "DUO" at Daljeon-Li Lake near the POSTECH campus. The Daljeon-Li Lake is an artificial lake for agriculture use. DUO measured the depth and temperature of water and the quality of water during the navigation. It was lots of fun even thought it was scorching hot (over 30 degree C). I am so proud of our group members and appreciate their hard work at the site. Please see a video of DUO's first landing here <click>.

We will use the in-situ data from DUO to construct the map of water quality and quantity of Daljeon-Li Lake and investigate interactions of water quality and water quantity over time and space.


Kwanghun Lee (Graduate Research Intern) joins our research group. Welcome aboard!


We had a two-day workshop and the site demo for unmanned boat, DUO, with two engineers from Dongmoon ENT. Now, we have a bunch of data from measuring water depth and speed, and quality every second.

Thanks to Dongmoon ENT engineers who visited us and gave a tutorial workshop and a test of DUO's first launch. Thanks to our group members who participated the two-day workshops.

We are looking forward to another launch of DUO soon.


A manuscript about dam-related hazard potential was accepted in Water (JIF: 2.54). The first and second authors are Mr. Junho Song and Ms. Madden Sciubba (University of Alabama). This paper used the information of around 70,000 (out of 90,000+) US dams from the 2018 National Inventory of Dam (NID) database to assess their cumulative impact and risk of the at the regional scales of the 12 NOAA Rvier Forecasting Center (RFC).

Good job and congrats, Junho and Madden!


A manuscript about Paleohydrology was accepted in Water (JIF: 2.54). This work was supported by the EPA Gulf of Mexico Program (Lead-PI: Matthew Therrell (University of Alabama) and the NSF Paleo Perspectives on Climate Change (P2C2) program (Lead-PI: Glenn Tootle (University of Alabama)). I joined these two projected as a co-PI at the University of Alabama, Tuscaloosa.


Anqi Liu (PhD) and Eunmi Lee (MSE) join our research group. Welcome aboard!


Dr. Kam's paper about the 2012 US drought was accepted and is now available on-line.

Kam, J., S. Kim, and J. Roundy, 2021, Did a skillful prediction of near-surface temperatures help or hinder forecasting of the 2012 US drought?, Environ. Res. Lett. https://doi.org/10.1088/1748-9326/abe1f6.

This paper was initially concevied by the results from Dr. Kam's ERL paper in 2014. The authors are Sungyoon Kim (a PhD student at the University of Alabama) and Dr. Joshua Roundy (an assistant professor of the University of Kansas).


A remotely operated boat with an Acoustic Doppler Current Profile (ADCP; flow speed and water depth) and an EXO2 environmental sensor (water quality) arrived at our lab.

We named this boat "DUO" since it can measure simultaneously water quantity and water quality data along river streams. In March, we will have a tutorial workshop with engineers from DONGMOON ENT. Co., Ltd. Welcome aboard, Duo!


Dr. Kam's paper about the 2015-19 Western Cape Drought was published in Bulletin of the American Meteorological Society's special issue of "Explaining Extreme Events of 2019 from a climate perspective" (JIF:9.38 and Rank: 2/93 (Meteorology & Atmospheric Sciences)). This work focused on understanding how anthropogenic influences affect the long sustained Western Cape drought over 2015-2019 using the Coupled Model Intercomparison Project Phase 6 (CMIP6).

The co-authors include Drs. Seung-Ki Min (POSTECH), Piotr Wolski (U of Cape Town, South Africa), and Jong-Seong Kug (POSTECH).

Another article from Princeton's contribution to the research fields of Water, drought and flooding. It presents Princeton's environmental excellence over the last half-century. I am very proud of my PhD study about US drought mechanisms and predictability under the guidance of Profs. Eric F Wood and Justin Sheffield (now at University of Southampton, UK).


On the Princeton Homepage, you can find a blog about a retrospective looking at the past half-century of climate modeling at Princeton [link]. This five-minute reading will make you understand the milestones of the half-century history of climate modeling at Princeton. Please check this blog if you are interested.

This long-lasting collaboration between the Princeton Atmospheric and Oceanic Science program and NOAA Geophysical Fluid Dynamics Laboratory is an exemplary collaboration between an academic institution and a government agency's research center to achieve one common goal, "Climate Modeling".

Numerous of graduate students and researchers at Princeton are all the beneficiaries through it. I am very proud of having my postdoc period there under the mentorship of Tom Knutson and Chris Milly.


Dr. Kam has a co-author paper accepted in Science of the Total Environment (JIF:6.5 and Rank: 22/265 (Environmental Science)). This work focused on understanding how people received the risk of flood and drought from the retrospective (past) and prospective (future) views via an integrated (quantitative and qualitative) assessment. The title of the paper is "Retrospective and Prospective Evaluations of Drought and Flood".

The author includes Dr. Wanyun Shao (lead author, Department of Geography at the University of Alabama).
