A paper submitted, a seed grant received, & workshop and seminars in Beijing and Seoul

May/June 2018

[Paper submission]

A research paper that I led has been recently submitted to Water Resources Research journal. This paper is about introducing two useful theories that can be used to re-frame the modeling of two well-known sociohydrologic phenomena (the levee effect and pendulum swing).

Title: From Place-Based Modeling Toward General Theories of Sociohydrology: Lessons from Social-ecological Systems 

Authors: David J. Yu, Heejun Chang, Taylor Davis, Vicken Hillis, Landon Marston, Woisok Oh, Murugesu Sivapalan, Timothy Waring

Landon Marston, one of the co-authors, is my close collaborator and we have worked together for Purdue’s seed grant program as well as NSF HDBE. It was also an honor to have the paper co-authored by Professor Murugesu Sivapalan (who is the father of socio-hydrology). 

[Seed grant award]

Also, I received a small seed grant Purdue’s Center for the Environment as PI (in collaboration with Dr. BC Min at Purdue CAIT)

[Invited talks and workshop]

Invited to and attended a sociohydrology workshop hosted by Tsinghua Univ. in Beijing, China. Interacted with Professor Murugesu Sivapalan and Gunther Bloeshl. On the way back, I stopped over in S. Korea and gave seminars at the Department of Geography, Seoul National University and the Department of Urban Planning & Engineering, Yonsei University.

A new paper accepted at Water Resources Research

Good news. A paper that I participated as its corresponding author and led by one of my graduate students has been accepted at a top journal in the field of water resources and hydrological sciences: Water Resources Research.

Title: Effects of flood control strategies on flood resilience under socio-hydrological disturbances

Abstract: A community capacity to cope with flood hazards, or community flood resilience, emerges from the interplay of hydrological and social processes. This interplay can be significantly influenced by the flood control strategy adopted by a society, i.e., how a society sets its desired flood protection level and strives to achieve this goal. And this interplay can be further complicated by rising land-sea level differences, seasonal water level fluctuations, and economic change. But not much research has been done on how various forms of flood control strategies affect human-flood interactions under these disturbances and therefore flood resilience in the long run. The current study is an effort to address these issues by developing a conceptual model of human-flood interaction mediated by flood control strategies. Our model extends the existing model of Yu et al. (2017), who investigated the flood resilience of a community-based flood protection system in coastal Bangladesh. The major extensions made in this study are inclusions of various forms of flood control strategies (both adaptive and non-adaptive ones), the challenge of rising land-sea level differences, and various high tide level scenarios generated from modifying the statistical variances and averages. Our results show that adaptive forms of flood control strategies tend to outperform non-adaptive ones for maintaining the model community’s flood protection system. Adaptive strategies that dynamically adjust target flood protection levels through close monitoring of flood damages and social memories of flood risk can help the model community deal with various disturbances.

USDA NIFA seed grant received as a co-PI

A proposal that I participated as a co-PI (along with other researchers in Idaho and Purdue) to USDA NIFA seed grant program has been awarded.

Project Title: Measuring feedbacks between farmer adaptation to irrigation water restrictions, land use change, and water availability in southeast Idaho.

A larger proposal based in this proposal has been submitted to NSF DRMS in January 2018.

Two co-authored papers have been submitted

Two Purdue graduate students who took my courses ( community resilience, dynamics of social-ecological-technical systems) led and recently completed two manuscripts, to which I contributed as a co-author. These two papers were recently submitted to Natural Hazard and International Journal of Sustainable Transportation. Great job, Juyeong and Davis!

Three co-authored papers submitted

Three co-authored papers (of which two are led by my graduate students) have been submitted to a special section “Socio-hydrology: Spatial and Temporal Dynamics of Coupled Human-Water Systems” in Water Resources Research.

Delivered invited talks at JpGU-AGU 2017 meeting and several universities in Korea

A couple weeks ago, I delivered an invited talk at JpGU-AGU 2017 meeting in Chiba, Japan. Title of the talk is “A behavioral approach to understanding human-water interactions under hydrological variability“. Honored to have met and spent time with leading scholars of socio-hydrology and global hydrology such as Murugesu Sivapalan and Taikan Oki. I also had an unexpected reunion with my PhD committee member there, Professor Rachata Muneepeerakul who is now at University of Florida.

After the JpGU-AGU meeting, I traveled to Korea to give invited talks at several Korean universities (Korea University, HongIk University, UNIST, Yonsei). I thank Professors KyoungRok Paik, Chon Jin Hyoung, Jeryang Park, and Yeonjoo Kim for hosting me. I also visited SNU and spent time talking with several professors. I especially thank Professor Dowon Lee. He invited me to spend time at SNU in 2011 when I was a graduate student. Professor Youngryeol Ryu also shared his heart-felt insights on how to manage a lab group. Thank you all for the wonderful time.
