Environ. Eng. Res. 2018; 23(2): 150-158 pISSN 1226-1025 https://doi.org/10.4491/eer.2017.067 eISSN 2005-968X Evaluation of the tributaries by influence index on the mid-lower portion of the Nakdong River basin Shun-Hwa Lee1, Seung-Gyu Jung1, Seoung-Muk Park1, Byung-Dae Lee2† 1Department of Environmental Engineering, Yeungnam University, Gyeongsan 38541, Republic of Korea 2Department of Health Management, Uiduk University, Gyeongju 38004, Republic of Korea ABSTRACT The deteriorating role of Nakdong River due to the Four Major Rivers Project has caused a series of problems, including water pollution, drying streams, aggravation of the hydroecology. Geumho River and Gyeongseong-cheon had a higher concentration index and is believed to impact the water quality of the main stream. The influence index of Geumho River and Nam River between 2015 and 2016, which have a large amount of discharge, was the highest among the tributaries in terms of the load material balance. Showing the highest average concentration and average load in the index assessment, Geumho River is believed to require an intensive management for improving the water quality of the main stream. Furthermore, when the cumulative percentage of the average concentration and average load was compared based on the water quality improvement of the tributaries mixed to Nakdong River, which was set to 60%, Geumho River, Nam River, Topyeong-cheon, and Cha-cheon, which showed the highest ratio in that order, were determined to require a water quality management program as a priority.

Green Korea 2001 in Pursuit of Economic and Environmental Sustainability Ministry of Environment Republic of Korea
Green Korea 2001 In pursuit of economic and environmental sustainability Ministry of Environment Republic of Korea Preface The past century has witnessed humankind benefit from the material progress made possible due to scientific and technological achievements. At the same time, however, we saw our planet come under ever-increasing stress that now challenges its ability to provide for future generations. Human activities are causing climate change; oceans are rising and threatening entire societies. Seemingly everywhere around us we see greater water and air pollution, growing waste, and shrinking green space. If this situation continues, our ways of life and possibly our very survival will not be sustained. It is time for us to re-evaluate the lifestyles of the past century and harness all the wisdom we have, as a nation and as a community, to find ways to achieve a balanced coexistence between human activities and the ecosphere. The Earth is the source of life for all and is where our children and their children will live. It is imperative that we serve as good stewards and bequeath the planet to them in a better state than it is now. Maintaining sustainability is, at its essence, both a survival strategy and an obligation we have towards future generations, as a government, as businesses, and as individuals. The Korean government, in keeping with the demands of the times, has been pursuing environmental policies based on sustainability. On World Environment Day (June 5, 2000), President Kim Dae Jung announced his environmental vision of expanding the meaning of peace to include the concept of genuine harmony and reconciliation between human societies and nature. -

Development of Flood Tracking Technique for Flood Disaster Management in Urban Areas
Sustainable Water Resources Management XI 221 DEVELOPMENT OF FLOOD TRACKING TECHNIQUE FOR FLOOD DISASTER MANAGEMENT IN URBAN AREAS DONG HO KANG1, SUK HO LEE2 & BYUNG SIK KIM1 1Department of Urban and Environmental Disaster Prevention Engineering, Kangwon National University, Republic of Korea 2Risk Management Research Department, UNO Co., Ltd., Republic of Korea ABSTRACT The change in precipitation due to climate change has induced local and torrential rainfalls. As a result, protected lowlands have an increased risk of damage caused by river inundation and subsequent flooding. Thus, it is necessary to have the technology to predict the damage due to flooding in a protected lowland. This study developed a distributed flood and inundation model called Simplified Inundation Model (SIMOD) to simulate a flooding path for identifying how flooding caused by river embankment’s breakage is inundated and spread in a protected lowland. Two methods were applied to simulate a flood path: the multiple flow direction method (MFDM) and the flat-water assumption (FWA) method. Virtual scenarios were set to calculate an inundation range over time in the Seongseoje, located downstream of the Geumho river, and evaluate the model. In addition, the urban inundation analysis was executed using the SIMOD. The results were compared to results from using the commercial inundation analysis two-dimensional flood routing model (FLO-2D) to verify the model’s applicability. The study applied the digital elevation model (DEM) terrain data for conventional flooding analysis and digital surface model (DSM) terrain data to represent urban building groups and road distribution. The 24-hour simulation was done less than 7 minutes using the SIMOD, and the difference in flooded areas was less than 20% compared to FLO-2D.
