**About the Editors**

#### **Il-Moon Chung**

Dr. Il-Moon Chung is a Groundwater Hydrologist and a Senior Research Fellow at the Korea Institute of Civil Engineering and Building Technology (KICT), South Korea. He received his Ph.D. from the Department of Civil Engineering at Yonsei University in 1998 with "Hydrogeological modeling of underground storage cavern and analysis of solute transport". After working at the SK Engineering & Construction Research Center for 3 years, he has been conducting research on groundwater management in Korea at KICT since 2002. His special interest is "surface water-groundwater integrated hydrological analysis", and he has developed a fully integrated SWAT-MODFLOW model. From 2012 to 2013, he conducted "Groundwater management options in Korea" research with Dr. Marios Sophocleous as a visiting professor at the Kansas Geological Survey. He has over 140 peer reviewed journal papers so far, and is serving as a Senior Editor of KSCE J. of Civil and Environmental Engineering Research (2022) and the Chief Editor of J. of Korea Water Resources Association (2021–2022).

#### **Sun Woo Chang**

Dr. Sun Woo Chang is currently the Research Fellow of Korea Institute of Civil Engineering and Building Technology (KICT), South Korea. Dr. Chang received her B.S. and M.Sc. in Seoul National University in 2001 and 2003, respectively. She majored in saltwater intrusion processes in saturated porous media systems in Department of Civil Engineering of Auburn University for her Ph.D. from 2008 to 2012. Before she joined in KICT, she worked as a researcher at Korea Institute of S&T Evaluation and Planning (KISTEP) from 2003 to 2006, and a post-doctoral researcher at Korea Institute of Geoscience and Mineral Resources (KIGAM) from 2010 to 2013. She has served on various scientific society including Korea Federation of Women's Sciences & Technology Association (KOFWST), Korean Society of Soil and Groundwater Environment (KOSSGE), and the Korean Society of Civil Engineers (KSCE). Recent research focuses on the flow and transport of multiple contaminant species, the dynamics of seawater intrusion (SWI), assessment of the vulnerability of coastal aquifers, and surface water-groundwater interactions.

#### **Yeonsang Hwang**

Prof. Yeonsang Hwang, an Associate Professor at Arkansas State University and a Hydrologist, is most interested in the study of the impact of climate variability on water systems. His early research works have been done through the support of two NOAA RISA (Regional Integrated Sciences and Assessments) programs in Colorado (WWA, Western Water Assessment) and South Carolina (CISA, Integrated Sciences and Assessments) in the area of uncertainties in daily rainfall data, the impact of climate variability in watershed modeling, ensemble forecast of drought indices, and a residual re-sampling technique. RISA teams are organized to develop and deliver water/climate-related information and research results to various stakeholders through an interdisciplinary setup. In recent years, he works on a large-scale comprehensive watershed study on the White River with the U.S. Army Corps of Engineers. As a research member and a water engineer, he worked for LG Engineering and Construction (currently GS E&C) from 1993 to 2001. He was involved in various projects related to water resources, water quality issues, and other general civil engineering problems. With these engineering experiences, he has been registered as a professional engineer in Korea.

#### **Yeonjoo Kim**

Prof. Yeonjoo Kim is currently the associate professor at the Department of Civil and Environmental Engineering, Yonsei University, South Korea. She earned her B.Sc. at Yonsei University in 2001 and her S.M. at MIT in 2003. Prof. Kim completed her Ph.D. at the University of Connecticut in 2006 with a dissertation titled soil moisture-vegetation-precipitation feedback at the seasonal time scale over North America. She worked as a postdoctoral fellow at Harvard University from 2006 to 2009 and was awarded the NASA Postdoctoral Program fellowship in 2009 for working at NASA/GISS. She then moved back to Korea to work as a senior research scientist at the Korea Environment Institute from 2010 until 2015, when she joined Yonsei University as a faculty member. Prof. Kim seeks to understand the interactions between hydrological processes and other physical, biological, and societal processes within the earth system. She developed and utilized various numerical models, including land surface-terrestrial biosphere models and watershed-scale hydrologic models, together with data from ground-based and remotely sensed measurements.
